Constructor Detail

SynchronousViewLifecycleProcessor

public SynchronousViewLifecycleProcessor(ViewLifecycle lifecycle)

Creates a new synchronous processor for a lifecycle.

Parameters:

lifecycle - The lifecycle to process.

Method Detail

offerPendingPhase

public void offerPendingPhase(ViewLifecyclePhase pendingPhase)

Queues a lifecycle phase to be processed within the lifecycle associated with this processor.

A phase submitted using this method will be added to the end of the queue, to be processed after all other phases currently in the queue have been submitted.

Parameters:

pendingPhase - The phase to be processed within the lifecycle associated with this processor.

pushPendingPhase

public void pushPendingPhase(ViewLifecyclePhase phase)

Pushes lifecycle phases to be processed within the lifecycle associated with this processor.

A phase submitted using this method will be added to the front of the queue, to be processed by the next available processor.

Parameters:

phase - The phase to be processed within the lifecycle associated with this processor.

performPhase

public void performPhase(ViewLifecyclePhase initialPhase)

Performs a lifecycle phase according to this processor's semantics, blocking until the phase has been completely processed. Once the initial phase has been completely processed, this method will return.

Parameters:

initialPhase - The initial lifecycle phase

getActivePhase

public ViewLifecyclePhase getActivePhase()

Gets the phase actively being processing on the current thread.

Returns:

lifecycle phase active on the current thread

getRenderingContext

public LifecycleRenderingContext getRenderingContext()

Gets a thread-local rending context for invoking FreeMarker operations on the current thread.

Returns:

rending context for invoking FreeMarker operations on the current thread

getExpressionEvaluator

public ExpressionEvaluator getExpressionEvaluator()

Returns an instance of ExpressionEvaluator that can be used for evaluating expressions contained on the view.

A ExpressionEvaluator must be initialized with a model for expression evaluation. One instance is constructed for the view lifecycle and made available to all components/helpers through this method

Returns:

instance of ExpressionEvaluator
