Nested Class Summary

Nested Classes

Modifier and Type	Class and Description
protected class	AVMFileDirContext.AVMFileResource This specialized resource implementation avoids opening the IputStream to the file right away (which would put a lock on the file).
protected class	AVMFileDirContext.AVMFileResourceAttributes This specialized resource attribute implementation does some lazy reading (to speed up simple checks, like checking the last modified date).

protected boolean getUseAVMRemote()

setDocBase

public void setDocBase(String docBase)

Set the document root.

Overrides:

setDocBase in class org.apache.naming.resources.FileDirContext

Parameters:

docBase - The new document root

Throws:

IllegalArgumentException - if the specified value is not supported by this implementation

IllegalArgumentException - if this would create a malformed URL

allocate

public void allocate()

Overrides:

allocate in class org.apache.naming.resources.BaseDirContext

release

public void release()

lookup

public Object lookup(String name)
              throws NamingException

Retrieves the named object.

Specified by:

lookup in interface Context

Overrides:

lookup in class org.apache.naming.resources.FileDirContext

Parameters:

name - the name of the object to look up

Returns:

the object bound to name

Throws:

NamingException - if a naming exception is encountered

unbind

public void unbind(String name)
            throws NamingException

Unbinds the named object. Removes the terminal atomic name in name from the target context--that named by all but the terminal atomic part of name.

This method is idempotent. It succeeds even if the terminal atomic name is not bound in the target context, but throws NameNotFoundException if any of the intermediate contexts do not exist.

Specified by:

unbind in interface Context

Overrides:

unbind in class org.apache.naming.resources.FileDirContext

Parameters:

name - the name to bind; may not be empty

Throws:

NameNotFoundException - if an intermediate context does not exist

NamingException - if a naming exception is encountered

rename

public void rename(String oldName,
          String newName)
            throws NamingException

Binds a new name to the object bound to an old name, and unbinds the old name. Both names are relative to this context. Any attributes associated with the old name become associated with the new name. Intermediate contexts of the old name are not changed.

Specified by:

rename in interface Context

Overrides:

rename in class org.apache.naming.resources.FileDirContext

Parameters:

oldName - the name of the existing binding; may not be empty

newName - the name of the new binding; may not be empty

Throws:

NameAlreadyBoundException - if newName is already bound

NamingException - if a naming exception is encountered

list

public NamingEnumeration<NameClassPair> list(String name)
                                      throws NamingException

Enumerates the names bound in the named context, along with the class names of objects bound to them. The contents of any subcontexts are not included.

If a binding is added to or removed from this context, its effect on an enumeration previously returned is undefined.

Specified by:

list in interface Context

Overrides:

list in class org.apache.naming.resources.FileDirContext

Parameters:

name - the name of the context to list

Returns:

an enumeration of the names and class names of the bindings in this context. Each element of the enumeration is of type NameClassPair.

Throws:

NamingException - if a naming exception is encountered

listBindings

public NamingEnumeration<Binding> listBindings(String name)
                                        throws NamingException

Enumerates the names bound in the named context, along with the objects bound to them. The contents of any subcontexts are not included.

If a binding is added to or removed from this context, its effect on an enumeration previously returned is undefined.

Specified by:

listBindings in interface Context

Overrides:

listBindings in class org.apache.naming.resources.FileDirContext

Parameters:

name - the name of the context to list

Returns:

an enumeration of the bindings in this context. Each element of the enumeration is of type Binding.

Throws:

NamingException - if a naming exception is encountered

listBindings

public NamingEnumeration<Binding> listBindings(String name,
                                      boolean include_background)
                                        throws NamingException

Throws:

NamingException

destroySubcontext

public void destroySubcontext(String name)
                       throws NamingException

Destroys the named context and removes it from the namespace. Any attributes associated with the name are also removed. Intermediate contexts are not destroyed.

This method is idempotent. It succeeds even if the terminal atomic name is not bound in the target context, but throws NameNotFoundException if any of the intermediate contexts do not exist. In a federated naming system, a context from one naming system may be bound to a name in another. One can subsequently look up and perform operations on the foreign context using a composite name. However, an attempt destroy the context using this composite name will fail with NotContextException, because the foreign context is not a "subcontext" of the context in which it is bound. Instead, use unbind() to remove the binding of the foreign context. Destroying the foreign context requires that the destroySubcontext() be performed on a context from the foreign context's "native" naming system.

Specified by:

destroySubcontext in interface Context

Overrides:

destroySubcontext in class org.apache.naming.resources.FileDirContext

Parameters:

name - the name of the context to be destroyed; may not be empty

Throws:

NameNotFoundException - if an intermediate context does not exist

NotContextException - if the name is bound but does not name a context, or does not name a context of the appropriate type

NamingException

lookupLink

public Object lookupLink(String name)
                  throws NamingException

Retrieves the named object, following links except for the terminal atomic component of the name. If the object bound to name is not a link, returns the object itself.

Specified by:

lookupLink in interface Context

Overrides:

lookupLink in class org.apache.naming.resources.FileDirContext

Parameters:

name - the name of the object to look up

Returns:

the object bound to name, not following the terminal link (if any).

Throws:

NamingException - if a naming exception is encountered

getNameInNamespace

public String getNameInNamespace()
                          throws NamingException

Retrieves the full name of this context within its own namespace.

Many naming services have a notion of a "full name" for objects in their respective namespaces. For example, an LDAP entry has a distinguished name, and a DNS record has a fully qualified name. This method allows the client application to retrieve this name. The string returned by this method is not a JNDI composite name and should not be passed directly to context methods. In naming systems for which the notion of full name does not make sense, OperationNotSupportedException is thrown.

Specified by:

getNameInNamespace in interface Context

Overrides:

getNameInNamespace in class org.apache.naming.resources.FileDirContext

Returns:

this context's name in its own namespace; never null

Throws:

OperationNotSupportedException - if the naming system does not have the notion of a full name

NamingException - if a naming exception is encountered

Specified by:

getAttributes in interface DirContext

Overrides:

getAttributes in class org.apache.naming.resources.FileDirContext

Parameters:

name - the name of the object from which to retrieve attributes

attrIds - the identifiers of the attributes to retrieve. null indicates that all attributes should be retrieved; an empty array indicates that none should be retrieved

Returns:

the requested attributes; never null

Throws:

NamingException - if a naming exception is encountered

public void modifyAttributes(String name,
                    int mod_op,
                    Attributes attrs)
                      throws NamingException

Modifies the attributes associated with a named object. The order of the modifications is not specified. Where possible, the modifications are performed atomically.

Specified by:

modifyAttributes in interface DirContext

Overrides:

modifyAttributes in class org.apache.naming.resources.FileDirContext

Parameters:

name - the name of the object whose attributes will be updated

mod_op - the modification operation, one of: ADD_ATTRIBUTE, REPLACE_ATTRIBUTE, REMOVE_ATTRIBUTE

attrs - the attributes to be used for the modification; may not be null

Each modification specifies a modification operation code and an attribute on which to operate. Where possible, the modifications are performed atomically.

Specified by:

modifyAttributes in interface DirContext

Overrides:

modifyAttributes in class org.apache.naming.resources.FileDirContext

Parameters:

name - the name of the object whose attributes will be updated

mods - an ordered sequence of modifications to be performed; may not be null

Throws:

AttributeModificationException - if the modification cannot be completed successfully

NamingException - if a naming exception is encountered

bind

public void bind(String name,
        Object obj,
        Attributes attrs)
          throws NamingException

Binds a name to an object, along with associated attributes. If attrs is null, the resulting binding will have the attributes associated with obj if obj is a DirContext, and no attributes otherwise. If attrs is non-null, the resulting binding will have attrs as its attributes; any attributes associated with obj are ignored.

Specified by:

bind in interface DirContext

Overrides:

bind in class org.apache.naming.resources.FileDirContext

Parameters:

name - the name to bind; may not be empty

obj - the object to bind; possibly null

attrs - the attributes to associate with the binding

Throws:

NameAlreadyBoundException - if name is already bound

InvalidAttributesException - if some "mandatory" attributes of the binding are not supplied

NamingException - if a naming exception is encountered

rebind

public void rebind(String name,
          Object obj,
          Attributes attrs)
            throws NamingException

Binds a name to an object, along with associated attributes, overwriting any existing binding. If attrs is null and obj is a DirContext, the attributes from obj are used. If attrs is null and obj is not a DirContext, any existing attributes associated with the object already bound in the directory remain unchanged. If attrs is non-null, any existing attributes associated with the object already bound in the directory are removed and attrs is associated with the named object. If obj is a DirContext and attrs is non-null, the attributes of obj are ignored.

Specified by:

rebind in interface DirContext

Overrides:

rebind in class org.apache.naming.resources.FileDirContext

Parameters:

name - the name to bind; may not be empty

                            throws NamingException

Creates and binds a new context, along with associated attributes. This method creates a new subcontext with the given name, binds it in the target context (that named by all but terminal atomic component of the name), and associates the supplied attributes with the newly created object. All intermediate and target contexts must already exist. If attrs is null, this method is equivalent to Context.createSubcontext().

Specified by:

createSubcontext in interface DirContext

Overrides:

createSubcontext in class org.apache.naming.resources.FileDirContext

The range of support for schemas is directory-specific.

Specified by:

getSchema in interface DirContext

Overrides:

getSchema in class org.apache.naming.resources.FileDirContext

Parameters:

Searches in the named context or object for entries that satisfy the given search filter. Performs the search as specified by the search controls.

Specified by:

search in interface DirContext

Overrides:

search in class org.apache.naming.resources.BaseDirContext

Parameters:

name - the name of the context or object to search

filter - the filter expression to use for the search; may not be null

cons - the search controls that control the search. If null, the default search controls are used (equivalent to (new SearchControls())).

Returns:

an enumeration of SearchResults of the objects that satisfy the filter; never null

Throws:

InvalidSearchFilterException - if the search filter specified is not supported or understood by the underlying directory

InvalidSearchControlsException - if the search controls contain invalid settings

NamingException - if a naming exception is encountered

search

public NamingEnumeration<SearchResult> search(Name name,
                                     Attributes matchingAttributes)
                                       throws NamingException

Searches in a single context for objects that contain a specified set of attributes. This method returns all the attributes of such objects. It is equivalent to supplying null as the atributesToReturn parameter to the method search(Name, Attributes, String[]).

Specified by:

search in interface DirContext

Overrides:

search in class org.apache.naming.resources.BaseDirContext

Parameters:

name - the name of the context to search

matchingAttributes - the attributes to search for. If empty or null, all objects in the target context are returned.

Returns:

a non-null enumeration of SearchResult objects. Each SearchResult contains the attributes identified by attributesToReturn and the name of the corresponding object, named relative to the context named by name.

Throws:

NamingException - if a naming exception is encountered

search

public NamingEnumeration<SearchResult> search(Name name,
                                     Attributes matchingAttributes,
                                     String[] attributesToReturn)
                                       throws NamingException

Searches in a single context for objects that contain a specified set of attributes, and retrieves selected attributes. The search is performed using the default SearchControls settings.

Specified by:

search in interface DirContext

Overrides:

search in class org.apache.naming.resources.BaseDirContext

Parameters:

name - the name of the context to search

matchingAttributes - the attributes to search for. If empty or null, all objects in the target context are returned.

attributesToReturn - the attributes to return. null indicates that all attributes are to be returned; an empty array indicates that none are to be returned.

Returns:

a non-null enumeration of SearchResult objects. Each SearchResult contains the attributes identified by attributesToReturn and the name of the corresponding object, named relative to the context named by name.

Throws:

NamingException - if a naming exception is encountered

listBindings

public NamingEnumeration<Binding> listBindings(Name name)
                                        throws NamingException

Enumerates the names bound in the named context, along with the objects bound to them. The contents of any subcontexts are not included.

If a binding is added to or removed from this context, its effect on an enumeration previously returned is undefined.

Specified by:

listBindings in interface Context

Overrides:

listBindings in class org.apache.naming.resources.BaseDirContext

Parameters:

name - the name of the context to list

Returns:

an enumeration of the bindings in this context. Each element of the enumeration is of type Binding.

Throws:

NamingException - if a naming exception is encountered

list

public NamingEnumeration<NameClassPair> list(Name name)
                                      throws NamingException

Enumerates the names bound in the named context, along with the class names of objects bound to them. The contents of any subcontexts are not included.

If a binding is added to or removed from this context, its effect on an enumeration previously returned is undefined.

Specified by:

list in interface Context

Overrides:

list in class org.apache.naming.resources.BaseDirContext

Parameters:

name - the name of the context to list

Returns:

an enumeration of the names and class names of the bindings in this context. Each element of the enumeration is of type NameClassPair.

Throws:

NamingException - if a naming exception is encountered

avm_list

protected ArrayList<org.apache.naming.NamingEntry> avm_list(AVMNodeDescriptor avm_node,
                                                boolean include_background)

List the resources which are members of a collection (not a part of BaseDirContext).

Returns:

Vector containg NamingEntry objects

file

protected File file(String name)

Return a File object representing the specified normalized context-relative path if it exists and is readable. Otherwise, return null.

Overrides:

file in class org.apache.naming.resources.FileDirContext

Parameters:

name - Normalized context-relative path (with leading '/')
