public class FieldValue_Extensible
extends FieldValue_Object

FieldValue_Extensible provides an implementation of the FieldValue interface for the Extensible interface. Clasess which implement the Extensible interface allow for named fields to be added dynamically to their instances. These fields are managed in a hashtable. The FieldValue_Extensible implementation uses this hashtable as an optional place to locate fields after we have failed to find the desired field in the usual way.

createAccessor

public FieldValueAccessor createAccessor(java.lang.Object target,

Description copied from class: FieldValue_Object

Creates and returns a new FieldValueAccessor (by default, a ReflectionFieldValueAccessor) for the given target and fieldName. No caching is done by this method. This method is designed to be overridden by subclasses of FieldValue_Object which want to define their own specialized accessors. Note that the target is passed rather than its class so that accessors can be created at a finer granularity than class. Certain meta-data driven classes require this flexibility.

Overrides:

createAccessor in class FieldValue_Object

Parameters:

target - the object for which the accessor will be created

fieldName - the name of the field for which the accessor will be created

type - the type of accessor will be created (either FieldValue.Setter or FieldValue.Getter)

Returns:

a new FieldValueAccessor (ReflectionFieldValueAccessor by default)
