Parameters:

key - String

processor - FieldProcessor

get

public FieldProcessor get(String key)

Returns the FieldProcessor that was registered witht he specified key.

Parameters:

key - String

Returns:

FieldProcessor

buildField

public Field buildField(String fieldName,
                        FormCreationData data)

Attempts to build a Field. The method first tries to derive a key from the fieldname, then uses this key to look up a FieldProcessor. This FieldProcessor is then used to generate a Field.

Parameters:

fieldName - the name of the field to be created.

data - A data object used by the FieldProcessor to build the Field.

Returns:

a Field or null.

getFieldProcessor

protected FieldProcessor getFieldProcessor(String fieldName)

Returns a FieldProcessor for the given field name.

Parameters:

fieldName - String

Returns:

The FieldProcessor implementation for the field or null if there isn't one regsitered.

useDefaultProcessor

protected boolean useDefaultProcessor(String fieldName)

Determines if the defaultProcessor should be used.

Parameters:

fieldName - String

Returns:

true if the defaultProcessor should be used, otherwise false.

getKey

protected String getKey(String fieldName)

Derives the key used to look up the FieldProcessor from the fieldName.

Parameters:

fieldName - String

Returns:

the key used to look up the FieldProcessor.

setDefaultProcessor

public void setDefaultProcessor(FieldProcessor defaultProcessor)

Sets the default field processor instance.

Parameters:

defaultProcessor - the defaultProcessor to set
