Method Detail

getRegistrationKeys

public Object[] getRegistrationKeys()

Returns an array of Objects, each one implementing hashCode and equals, which is the group of keys by which the implementor can be obtained from the Registrar. For a "marshaller" that knows how to marshal a particular Object, the Class (or classes) of the Object might be used as a key (or keys), or a String (or Strings) representing the name of the type (or types) handled by the marshaller could be used as the key (or keys). For a message handler, an Integer (or Integers) representing the message type (or types) could be used as the key (or keys).

Returns:

An array of Objects that represent the kinds of things the implementor can handle.
