Method Detail

bindExpression

protected void bindExpression()

expressionIsLiteral

protected abstract void expressionIsLiteral()

Sub-classes of this abstract class must convert the el expression into a literal m_valueExpression is not guaranteed to be non-null, so it must be checked before being used. If m_valueExpression is null, the value must be extracted from the string m_elExpression and coerced into the proper type from there.

hasElExpression

protected boolean hasElExpression()

executeAction

public static GenericActionResult executeAction(GenericAction action)

executeAction

public static GenericActionResult executeAction(GenericAction action,
                                                boolean enabled)

executeAction

public GenericActionResult executeAction()

valueChanged

public void valueChanged(ValueExpression sourceExpression)

Specified by:

valueChanged in interface ValueChangeListener

Parameters:

sourceExpression - - the ValueExpression instance this listener was registered with
