Class CompositeComponentStackManager

java.lang.Object

com.sun.faces.component.CompositeComponentStackManager

public class CompositeComponentStackManager
extends Object

CompositeComponentStackManager is responsible for managing the two different composite component stacks currently used by Mojarra.

The stacks are identified by the CompositeComponentStackManager.StackType enum which has two elements, TreeCreation and Evaluation.

The TreeCreation stack represents the composite components that have been pushed by the TagHandlers responsible for building the tree.

The Evaluation stack is used by the EL in order to properly resolve nested composite component expressions.

Parameters:

compositeComponent - the component to push

stackType - the stack to push to the component to

Returns:

true if the component was pushed, otherwise returns false

push

public boolean push()

Pushes a component derived by the push logic to the Evaluation stack.

Returns:

true if the component was pushed, otherwise returns false

push

public boolean push(CompositeComponentStackManager.StackType stackType)
