Detailed Description

template<typename Resource, typename Dependency>
class ezDependencyTracker< Resource, Dependency >

A thread-safe dependency tracking system for managing resource invalidation.

This template class tracks dependencies between resources and their dependencies to allow invalidating resources when their dependencies are destroyed. When a dependency is destroyed, all resources that depend on it are automatically identified and an invalidation event is broadcast for each affected resource.

Template Parameters

Resource	The type of resource being tracked (e.g. bind groups)
Dependency	The base type of the dependencies (e.g., ezGALResource)

Member Function Documentation

AddResource()

template<typename Resource , typename Dependency >

void ezDependencyTracker< Resource, Dependency >::AddResource	(	Resource *	pResource,
		const ezSet< const Dependency * > &	dependencies
	)

Adds a resource and its dependencies to the tracking system.

This method registers a resource along with all of its dependencies. The resource will be automatically invalidated if any of its dependencies are destroyed. Each resource can only be added once - attempting to add the same resource again will trigger an assertion in debug builds.

Parameters

pResource	Pointer to the resource to track
dependencies	Set of dependencies that this resource depends on

DependencyDestroyed()

template<typename Resource , typename Dependency >

void ezDependencyTracker< Resource, Dependency >::DependencyDestroyed

(

Dependency *

pDependency

)

Notifies the tracker that a dependency has been destroyed.

This method should be called when a dependency object is about to be destroyed. It will identify all resources that depend on this dependency, remove the dependency relationships, and broadcast invalidation events for each affected resource.

Parameters

pDependency

Pointer to the dependency that is being destroyed

RemoveResource()

template<typename Resource , typename Dependency >

void ezDependencyTracker< Resource, Dependency >::RemoveResource

(

Resource *

pResource

)

Removes a resource from the tracking system.

This method removes the resource and all of its dependency relationships from the tracker. The resource will no longer receive invalidation events even if its former dependencies are destroyed.

Parameters

pResource

Pointer to the resource to remove from tracking
