Constructor Detail

StateManagerImpl

public StateManagerImpl(javax.faces.application.StateManager delegate)

Constructor for the StateManagerWrapper implmentation.

Parameters:

delegate - first delegate in the implementation chain.

Method Detail

writeState

public final void writeState(javax.faces.context.FacesContext context,
                             Object state)
                      throws IOException

Writes the given state into the current response.

This implementation of the writeState method buffers the current response before bypassing the responsiveness of writing the response state. This allows to the method to cache the current state date into the request attribute map so it can be restored in the future.

Overrides:

writeState in class javax.faces.application.StateManagerWrapper

Parameters:

context - current FacesContext instance.

state - current view state.

Throws:

IOException - when some output errors happen when encding the state.

getWrapped

protected final javax.faces.application.StateManager getWrapped()

Obtains the first delegate in the implementation chain.

Specified by:

getWrapped in class javax.faces.application.StateManagerWrapper

Returns:

first delegate in the chain.
