Method Detail

preMarshal

boolean preMarshal(Object object)

This method is called before an object is to be marshalled. In case of unchecked exceptions being thrown, those will be caught and logged, but the marshalling process will not be interrupted.

Parameters:

object - the Object about to be marshalled.

Returns:

false if the object should not be marshalled.

postMarshal

void postMarshal(Object object)

This method is called after an object has been marshalled. If #preMarshal returned false for a given Object, this method will not be called for that Object as marshalling will not take place. In case of unchecked exceptions being thrown, those will be caught and logged, but the marshalling process will not be interrupted.

Parameters:

object - the Object that was marshalled.
