Detailed Description

A PxBaseTask implementation with immediate execution and simple dependencies.

A PxLightCpuTask bypasses the PxTaskManager launch dependencies and will be submitted directly to your scene's CpuDispatcher. When the run() function completes, it will decrement the reference count of the specified continuation task.

You must use a full-blown PxTask if you want your task to be resolved by another PxTask, or you need more than a single dependency to be resolved when your task completes, or your task will not run on the CpuDispatcher.

PxLightCpuTask::PxLightCpuTask ( )

inline

virtual PxLightCpuTask::~PxLightCpuTask ( )

References NULL.

Member Function Documentation

PX_INLINE void PxLightCpuTask::addReference ( )

inlinevirtual

Manually increment this task's reference count. The task will not be allowed to run until removeReference() is called.

Implements PxBaseTask.

PX_INLINE PxBaseTask* PxLightCpuTask::getContinuation ( ) const

inline

Retrieves continuation task.

PX_INLINE PxI32 PxLightCpuTask::getReference ( ) const

inlinevirtual

Return the ref-count for this task.

Implements PxBaseTask.

PX_INLINE void PxLightCpuTask::release ( )

inlinevirtual

called by CpuDispatcher after run method has completed

Decrements the continuation task's reference count, if specified.

Implements PxBaseTask.

PX_INLINE void PxLightCpuTask::removeReference ( )

inlinevirtual

Manually decrement this task's reference count. If the reference count reaches zero, the task will be dispatched.

Implements PxBaseTask.

PX_INLINE void PxLightCpuTask::setContinuation ( PxTaskManager &  tm, PxBaseTask *  c  )

inline

Initialize this task and specify the task that will have its ref count decremented on completion.

Submission is deferred until the task's mRefCount is decremented to zero. Note that we only use the PxTaskManager to query the appropriate dispatcher.

Parameters

[in]	tm	The PxTaskManager this task is managed by
[in]	c	The task to be executed when this task has finished running

References PX_ASSERT.

PX_INLINE void PxLightCpuTask::setContinuation ( PxBaseTask *  c )

inline

Initialize this task and specify the task that will have its ref count decremented on completion.

This overload of setContinuation() queries the PxTaskManager from the continuation task, which cannot be NULL.

Parameters

[in]

c

The task to be executed after this task has finished running

References PxBaseTask::addReference(), and PX_ASSERT.
