Method Detail

registerHelper

public void registerHelper(java.lang.Class type,
                           ValueHelper helper)

Register a ValueHelper for a particular type. During [de]serialisation Objects flowing in/out of the persistance medium will be passed through this Helper, which will have the opportunity to convert them between Serializable and non-Serializable representations. Helpers will be returned in their registration order, so this is significant (as an Object may implement more than one interface or registered type).

Parameters:

helper -

public boolean deregisterHelper(java.lang.Class type)

findHelper
