Member Function Documentation

AddMessageHandler()

void XrdCl::InQueue::AddMessageHandler	(	MsgHandler *	handler,
		time_t	expires,
		bool &	rmMsg
	)

Add a listener that should be notified about incoming messages

Parameters

handler	message handler
expires	time when the message handler expires
rmMsg	will be set to true if a left over message matching the request has been removed from the queue

DiscardMessage()

bool XrdCl::InQueue::DiscardMessage ( Message &  msg, uint16_t &  sid  ) const

private

Discard messages that don't meet basic criteria and extract the message sid

Parameters

msg	message object
sid	extracted message sid used later for matching with the handler

Returns

true if message discarded, otherwise false

GetHandlerForMessage()

MsgHandler * XrdCl::InQueue::GetHandlerForMessage	(	std::shared_ptr< Message > &	msg,
		time_t &	expires,
		uint16_t &	action
	)

Get a message handler interested in receiving message whose header is stored in msg

Parameters

msg	message header
expires	handle's expiration timestamp
action	the action declared by the handler

Returns

handler or 0 if none is interested

ReAddMessageHandler()

void XrdCl::InQueue::ReAddMessageHandler	(	MsgHandler *	handler,
		time_t	expires
	)

Re-insert the handler without scanning the cached messages.

RemoveMessageHandler()

void XrdCl::InQueue::RemoveMessageHandler

(

MsgHandler *

handler

)

Remove a listener.

ReportStreamEvent()

void XrdCl::InQueue::ReportStreamEvent	(	MsgHandler::StreamEvent	event,
		XRootDStatus	status
	)

Report an event to the handlers.

ReportTimeout()

void XrdCl::InQueue::ReportTimeout

(

time_t

now = 0

)

Timeout handlers.
