_released

Constructor Summary

FacesContextImplBase(ExternalContext externalContext, ReleaseableExternalContext defaultExternalContext)
Base constructor.

Method Summary

protected void	assertNotReleased() has to be thrown in many of the methods if the method is called after the instance has been released!
Application	getApplication()
Map<Object,Object>	getAttributes() Returns a mutable map of attributes associated with this faces context when FacesContext.release is called the map must be cleared! Note this map is not associated with the request map the request map still is accessible via the FacesContext.getExternalContext.getRequestMap method! Also the scope is different to the request map, this map has the scope of the context, and is cleared once the release method on the context is called! Also the map does not cause any events according to the spec!

FacesContextImplBase

public FacesContextImplBase(ExternalContext externalContext,
                            ReleaseableExternalContext defaultExternalContext)

Base constructor. Calls FacesContext.setCurrentInstance(this);

Method Detail

release

public void release()

Releases the instance fields on FacesContextImplBase. Must be called by sub-classes, when overriding it!

Specified by:

release in class FacesContext

getExternalContext

public final ExternalContext getExternalContext()

Specified by:

getExternalContext in class FacesContext

getApplication

public final Application getApplication()

Specified by:

getApplication in class FacesContext

getExceptionHandler

public final ExceptionHandler getExceptionHandler()

Overrides:

getExceptionHandler in class FacesContext

setExceptionHandler

public final void setExceptionHandler(ExceptionHandler exceptionHandler)

Overrides:

setExceptionHandler in class FacesContext

isProcessingEvents

public final boolean isProcessingEvents()

Overrides:

isProcessingEvents in class FacesContext

setProcessingEvents

public final void setProcessingEvents(boolean processingEvents)

Overrides:

setProcessingEvents in class FacesContext

getELContext

public final javax.el.ELContext getELContext()

Overrides:

getELContext in class FacesContext

getAttributes

public final Map<Object,Object> getAttributes()

Returns a mutable map of attributes associated with this faces context when FacesContext.release is called the map must be cleared! Note this map is not associated with the request map the request map still is accessible via the FacesContext.getExternalContext.getRequestMap method! Also the scope is different to the request map, this map has the scope of the context, and is cleared once the release method on the context is called! Also the map does not cause any events according to the spec!

Overrides:

getAttributes in class FacesContext

Throws:

IllegalStateException - if the current context already is released!

Since:

JSF 2.0

Specified by:

setViewRoot in class FacesContext

getRenderKit

public final RenderKit getRenderKit()

Specified by:

getRenderKit in class FacesContext

assertNotReleased

protected final void assertNotReleased()

has to be thrown in many of the methods if the method is called after the instance has been released!
