Object getFieldChange(String fieldName)

Get the current persisted value of the field.

Parameters:

fieldName - the name of the field to access

Returns:

the value stored for the field, or null if no value is currently stored

hasFieldChange

boolean hasFieldChange(String fieldName)

Checks to see if there is a value stored for the indicated field.

persistFieldChange

void persistFieldChange(String fieldName,
                        Object newValue)

Posts a change to a persistent field. If the component is still loading, then this change is ignored. Otherwise, it is propagated, via the page to the PersistentFieldManager.

postRenderCleanup

void postRenderCleanup()

Allows the resources to cleanup any render-time only data.

queueRender

void queueRender(RenderQueue queue)

Invoked to make the receiver queue itself to be rendered.

getParameterAccess

ParameterAccess getParameterAccess(String parameterName)

Gets access object for the parameter.
