Field Detail

EMPTY_MESSAGE

public static final IsolateMessage EMPTY_MESSAGE

Really a global value. Immutable, and eternally referenceable, so giving everyone in the system a pointer to this is okay by me.

Overrides:

toString in class java.lang.Object

isIOMessage

abstract boolean isIOMessage()

Return true if this message contains an IO object suitable for stdio redirection.

pretranslate

void pretranslate()
            throws LinkSerializationException

Set up a message for translation. (Only used by serializables to make sure they're serialized before sending). Used by composite, too.

translate

INTERNAL translation of IsolateMessage XXX thrown exception is odd? (IOException for fd duping errors)
