toXml

public final java.lang.String toXml(java.lang.String extraOffset)

Dump state of this object into a XML ASCII string.

registerProgressListener

public I_ProgressListener registerProgressListener(I_ProgressListener listener)

forcePingFailure

protected boolean forcePingFailure()

Specified by:

forcePingFailure in class DispatchConnection

Returns:

true if the implementation has to throw an exception in case the ping is invoked when there is an ongoing write or read operation on the same connection. Normally it shall give false on the callback and true on the client side. The client side shall give true because otherwise if such a situation arizes it will never go in polling and no reconnect will be triggered.
