Method Detail

_jistPostInit

public void _jistPostInit()

Post-constructor call. Since constructors can not be blocking (JiST/Java limitation), we rewrite a regular socket constructor to two calls. This is the second one, and it can be blocking, because it is a regular method.

bind

public void bind(java.net.SocketAddress addr)

close
