Constructor & Destructor Documentation

◆ SoDeviceContextSharedGroup() [1/2]

SoDeviceContextSharedGroup::SoDeviceContextSharedGroup ( )

Creates a new SharedGroup.

◆ SoDeviceContextSharedGroup() [2/2]

SoDeviceContextSharedGroup::SoDeviceContextSharedGroup ( int id )

Creates a new SharedGroup with specific id.

Member Function Documentation

◆ add()

void SoDeviceContextSharedGroup::add ( SoDeviceContext * ctx )

Adds a device context to the group.

◆ contains() [1/2]

bool SoDeviceContextSharedGroup::contains ( const SoDeviceContext * ctx ) const

Returns TRUE if the passed context is part of the shared group.

◆ contains() [2/2]

bool SoDeviceContextSharedGroup::contains ( SoBaseContextCache * object ) const

Returns TRUE if the specified object is already in the list of notified objects.

To add or remove an object, from this list, the ref(object) and unref(object) methods can be used.

◆ dispose()

virtual void SoDeviceContextSharedGroup::dispose ( )

virtual

Force all attached objects to release the context, by calling their respective release function, and force deletion of the contained context.

◆ getContexts()

const SoDeviceContextSet & SoDeviceContextSharedGroup::getContexts ( ) const

Gets the list of contexts managed by this shared group.

◆ getId()

int SoDeviceContextSharedGroup::getId ( ) const

Gets the id of this shared group.

◆ getPrimaryContext()

SoDeviceContext * SoDeviceContextSharedGroup::getPrimaryContext ( ) const

Returns the first context found in the shared group.

◆ ref()

void SoDeviceContextSharedGroup::ref ( SoBaseContextCache * object = NULL )

Increment reference count.

Object is the ContextObject that should be triggered when this context is deleted.

◆ remove()

void SoDeviceContextSharedGroup::remove ( SoDeviceContext * ctx )

Removes a device context from the group.

◆ setId()

void SoDeviceContextSharedGroup::setId ( int id )

Sets a specific id for this shared group.

◆ unref()

void SoDeviceContextSharedGroup::unref ( SoBaseContextCache * object = NULL )

Decrement reference count.

Object is the ContextObject that was referenced originally.

If this call causes the reference count to go from 1 to 0 then the context is automatically deleted and all ContextObject that previously called ref(SoContextObject*) will be triggered for deletion (potentially asynchronously).
