Exception

needsImmediateDisconnection

protected abstract boolean needsImmediateDisconnection()

Returns true if the connection has to be closed immediately rather than sending a GOAWAY frame and waiting for the remaining streams. This method should return true when:

• ClientFactory is being closed.
• Server is being stopped.
• Received a GOAWAY frame with non-OK error code.
