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
andEvaluation
.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.
