                        throws IOException

Method will be called, when the connection gets connected.

Throws:

IOException

checkConnectFailed

protected final void checkConnectFailed(Throwable failure)

Method will be called in order to check if failure happened before Connection was reported as connected.

canWrite

public boolean canWrite()

Returns:

true if a write to this OutputSink will succeed, otherwise returns false.

canWrite

@Deprecated

Parameters:

handler - the WriteHandler that should be notified when it's possible to write length bytes.

length - the number of bytes or characters that require writing.
