Detailed Description
A native type that requires periodic updates from the core (movie_root).
Objects with this type of relay can be registered with movie_root, and recieve a callback on every advance. This type of Relay holds a reference to its parent as_object (owner). If a reference to this ActiveRelay is held by another object, it must be marked reachable so that its owner is not deleted by the GC. The function setReachable() is called on every GC run. It calls markReachableResources() and marks its owner.

Member Function Documentation
§ clean()
|
virtual |
Remove the ActiveRelay from movie_root's callback set.
This must be called before the Relay is destroyed!
Reimplemented from gnash::Relay.
References gnash::getRoot(), and gnash::movie_root::removeAdvanceCallback().
§ markReachableResources()
|
inlineprotectedvirtual |
Mark any reachable resources other than the owner.
Override this function if the subclass holds references to GC resources other than the owner.
Reimplemented in gnash::NetStream_as, and gnash::NetConnection_as.
Referenced by setReachable().
§ owner()
|
inline |
Return the as_object that this Relay is attached to.
Referenced by gnash::NetConnection_as::connect(), gnash::BufferedAudioStreamer::fetchWrapper(), gnash::NetStream_as::get_video(), gnash::NetConnection_as::getStream(), gnash::NetConnection_as::markReachableResources(), gnash::NetStream_as::markReachableResources(), gnash::NetConnection_as::notifyStatus(), gnash::NetStream_as::play(), gnash::movie_root::pushAction(), gnash::registerNetStreamNative(), gnash::NetStream_as::setAudioController(), gnash::NetConnection_as::setURI(), gnash::NetConnection_as::update(), gnash::NetStream_as::update(), and gnash::NetConnection_as::validateURL().
§ setReachable()
|
virtual |
Mark any other reachable resources, and finally mark our owner.
Do not override this function.
Reimplemented from gnash::Relay.
References markReachableResources(), and gnash::GcResource::setReachable().
Referenced by gnash::Video::markOwnResources(), gnash::NetStream_as::markReachableResources(), and gnash::movie_root::markReachableResources().
§ update()
|
pure virtual |
ActiveRelay objects must have an update() method.
The method will be called at the heart-beat frequency.
Implemented in gnash::NetStream_as, and gnash::NetConnection_as.
