Method Detail

register

public void register(java.lang.String key,
                     FieldProcessor processor)
Registers a FieldProcessor with this registry using the specified key.

Parameters:
key -
processor -

get

public FieldProcessor get(java.lang.String key)
Returns the FieldProcessor that was registered witht he specified key.

Parameters:
key -
Returns:

buildField

public Field buildField(java.lang.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(java.lang.String fieldName)
Returns a FieldProcessor for the given field name.

Parameters:
fieldName -
Returns:
The FieldProcessor implementation for the field or null if there isn't one regsitered.

useDefaultProcessor

protected boolean useDefaultProcessor(java.lang.String fieldName)
Determines if the defaultProcessor should be used.

Parameters:
fieldName -
Returns:
true if the defaultProcessor should be used, otherwise false.

getKey

protected java.lang.String getKey(java.lang.String fieldName)
Derives the key used to look up the FieldProcessor from the fieldName.

Parameters:
fieldName -
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
