Class EnablerConverter

java.lang.Object

net.sf.jguiraffe.gui.builder.enablers.EnablerConverter

All Implemented Interfaces:

org.apache.commons.beanutils.Converter

public class EnablerConverter
extends Object
implements org.apache.commons.beanutils.Converter

A specialized converter implementation for ElementEnabler objects.

This converter class is a thin wrapper around the EnablerBuilder class. In its convert(Class, Object) method it expects a string representation of an ElementEnabler which is compatible with the specifications understood by the builder. It passes this string to the builder and uses it to create the enabler. The resulting ElementEnabler is returned.

Implementation note: This class is stateless; therefore an instance can be shared between multiple components and invoked concurrently.
