IOException

validateHierarchy

protected abstract void validateHierarchy()

Validate the component hierarchy. This should only be called when project stage is Development.

Throws:

process

protected abstract void process(FacesContext context,
                                PhaseId phaseId)

Process the component according to the rules of the given phase ID.

Parameters:

context - The faces context to work with.

phaseId - The current phase ID.

processSuper

protected void processSuper(FacesContext context,
                            PhaseId phaseId)

Helper method to delegate the processing further to the UIComponentBase superclass which will handle all children.

Parameters:

context - The faces context to work with.

phaseId - The current phase ID.
