Member Function Documentation

processOnGPU()

bool Beatmup::TextureHandleFactory::processOnGPU ( GraphicPipeline &  gpu, TaskThread &  thread  )

inlineprivatevirtual

Executes the task on GPU.

Parameters

gpu	graphic pipeline instance
thread	associated task execution context

Returns

true if the execution is finished correctly, false otherwise

Reimplemented from Beatmup::AbstractTask.

Definition at line 42 of file external_bitmap.cpp.

                                                             {
            glGenTextures(1, &textureHandle);
            return true;
        }

process()

bool Beatmup::TextureHandleFactory::process ( TaskThread &  thread )

inlineprivatevirtual

Executes the task on CPU within a given thread.

Generally called by multiple threads.

Parameters

thread

associated task execution context

Returns

true if the execution is finished correctly, false otherwise

Implements Beatmup::AbstractTask.

        }

getUsedDevices()

TaskDeviceRequirement Beatmup::TextureHandleFactory::getUsedDevices ( ) const

inlineprivatevirtual

Communicates devices (CPU and/or GPU) the task is run on.

Reimplemented from Beatmup::AbstractTask.
