public void setDetails(javax.servlet.http.HttpServletRequest req, javax.servlet.http.HttpServletResponse resp, WebDAVHelper davHelper, NodeRef rootNode)Set the request/response details- Parameters:
req- HttpServletRequestresp- HttpServletResponsedavHelper- WebDAVHelperrootNode- NodeRef
-
isReadOnly
protected boolean isReadOnly()
Override and return true if the method is a query method only. The default implementation returns false.- Returns:
- Returns true if the method transaction may be read-only
-
getDepth
public final int getDepth()
Return the property find depth- Returns:
- int
-
execute
public void execute() throws WebDAVServerExceptionExecutes the method, wrapping the call toexecuteImpl()in an appropriate transaction and handling the error conditions.- Throws:
WebDAVServerException
-
executeImpl
protected abstract void executeImpl() throws WebDAVServerException, ExceptionAccess the content repository to satisfy the request and generates the appropriate WebDAV response.- Throws:
WebDAVServerException- a general server exceptionException- any unhandled exception
-
generateResponseImpl
protected void generateResponseImpl() throws ExceptionDoes nothing unless overridden - for reasons of backwards compatibility. Subclasses implementing this method should separate the WebDAV method execution logic from response generation logic. Execution logic should be contained in theexecuteImpl()method and should NOT contain any code that writes to the response. Conversely response generation logic should NOT contain any code relating to the desired effect of the WebDAV method (e.g. setting properties on a node) and should be contained purely within this method.Older methods, until refactored will not override this method, relying only on
executeImpl().- Throws:
Exception
-

Retrieves the request body as an XML document- Returns:
- The body of the request as an XML document or null if there isn't a body

protected void parseDepthHeader() throws WebDAVServerExceptionParses "Depth" request header- Throws:
WebDAVServerException
-
parseIfHeader
protected void parseIfHeader() throws WebDAVServerExceptionParses "If" header of the request. Stores conditions that should be checked. Parses both No-tag-list and Tagged-list formats See "10.4.2 Syntax" paragraph of the WebDAV specification for "If" header format.- Throws:
