Detailed Description

Collectable resource.

Instances of this class can be managed by a GC object.

Constructor & Destructor Documentation

GcResource()

gnash::GcResource::GcResource ( GC &  gc )

inline

Create a Garbage-collected resource associated with a GC.

Parameters

gc	The GC to register the resource with.

References gnash::GC::addCollectable().

~GcResource()

virtual gnash::GcResource::~GcResource ( )

inlineprotectedvirtual

Delete this resource.

This is protected to allow subclassing, but ideally it sould be private, so only the GC is allowed to delete us.

Member Function Documentation

clearReachable()

void gnash::GcResource::clearReachable ( ) const

inline

Clear the reachable flag.

Referenced by gnash::GC::~GC().

isReachable()

bool gnash::GcResource::isReachable ( ) const

inline

Return true if this object is marked as reachable.

Referenced by gnash::GC::addCollectable(), and gnash::GC::~GC().

markReachableResources()

virtual void gnash::GcResource::markReachableResources ( ) const

inlineprotectedvirtual

Scan all GC resources reachable by this instance.

This function is invoked everytime this object switches from unreachable to reachable, and is used to recursively mark all contained resources as reachable.

See setReachable(), which is the function to invoke against all reachable methods.

Feel free to assert(_reachable) in your implementation.

The default implementation doesn't mark anything.

Reimplemented in gnash::DisplayObject, gnash::as_object, gnash::Function, and gnash::Global_as.

References _, gnash::log_debug(), and gnash::typeName().

setReachable()

void gnash::GcResource::setReachable ( ) const

inline

Mark this resource as being reachable.

This can trigger further marking of all resources reachable by this object. If the object wasn't reachable before, this call triggers scan of all contained objects too.
