All Implemented Interfaces:
VariableResolver.DataSource
Enclosing class:
VariableResolver

public static class VariableResolver.BooleanDataSource
extends java.lang.Object
implements VariableResolver.DataSource

This VariableResolver.DataSource converts the given key to a Boolean. This is needed because JSF does not do this for you. When you call UIComponent.getAttributes().put(key, value), value is expected to be the correct type. Often Boolean types are needed. This VariableResolver.DataSource provides a means to supply a Boolean value.
