Detailed Description

The AbstractEventSource class is the base class for all objects that can be tracked using one or more file descriptors

A subclass can register multiple file descriptors to be tracked using updateFdWatch and remove them with removeFdWatch. This is internally forwarded to the

See also: EventDispatcher belonging to the AbstractEventSource.

In case there is activity on the file descriptor the EventDispatcher wakes up and forwards it to onFdReady.

Member Function Documentation

◆ eventDispatcher()

std::weak_ptr< EventDispatcher > zyppng::AbstractEventSource::eventDispatcher ( ) const

Returns the

See also: EventDispatcher that takes care of this event source

Definition at line 35 of file abstracteventsource.cc.

◆ onFdReady()

virtual void zyppng::AbstractEventSource::onFdReady	(	int	fd,
		int	events
	)

pure virtual

Called by the

See also: EventDispatcher when activity was detected on a registered fd. The events are set according to the activity on the file descriptor.

Implemented in zyppng::SocketNotifier.

◆ onSignal()

virtual void zyppng::AbstractEventSource::onSignal ( int signal )

pure virtual

Called when a event source has registered to receive unix signals

Note: this is not supported yet

Implemented in zyppng::SocketNotifier.

◆ updateFdWatch()

void zyppng::AbstractEventSource::updateFdWatch	(	int	fd,
		int	mode
	)

protected

Register or update a file descriptor poll mode.

Parameters

fd	The fd to add or update to the watchlist of the

See also: EventDispatcher

Parameters

mode	The watchmode used in the watchlist

See also: EventTypes

Definition at line 40 of file abstracteventsource.cc.

◆ removeFdWatch()

void zyppng::AbstractEventSource::removeFdWatch ( int fd )

protected

Removes the given fd from the

See also: EventDispatcher watchlist. After calling this no more events will be received by the object it was called on.
