Direct Known Subclasses:

BidiLink_Left, BidiLink_Neither, BidiLink_Right

abstract class BidirectionalLink

extends Link

A bidirectional connection between two Isolates. In terms of buffering/blocking behavior, acts as a pair of unidirectional Links. Subclasses implement left, right and neither case's send/receive. Neither case overrides isOpen and close, too.

Since:

1.5
