Public Types inherited from CYIAssetHardware
enum	RETENTION_POLICY { RETAIN = 0, UNLOAD }
	The YI_HW_ASSET_RETENTION_POLICY enum specifies the retention policy of static hardware assets from the CPU memory once they are loaded onto the GPU. It is globally configurable, where new CYIAssetHardware will be making use of it and the can also change directly per assets. Be aware that on some platform, it is best to leave the assets retained on the CPU side when the platform lifecycle has the ability to destroy the graphic context while the app still runs, giving You.i Engine the ability to re-load every assets back onto GPU memory really fast. A good example of such platform would be Android. More...

Member Function Documentation

virtual std::shared_ptr<IYIGPUObject> CYIAssetTexture::CreateGPUObject ( ) const

overrideprotectedvirtual

Each sub-type must implement this function and returns an IYIGPUObject representing the hardware type.

Implements CYIAssetTextureBase.

virtual std::pair<uint32_t, uint32_t> CYIAssetTexture::GetApproximateSize ( ) const

overridevirtual

Calculates and returns the approximate number of bytes currently used by this asset. The first item of the returned pair object represents the memory currently taken in the CPU main memory, and the second item of the returned pair object represents the memory currently taken in the GPU memory.

Note: This function only returns an approximate memory consumption as the exact memory consumption changes depending on the used C++ libraries and on the specific GPU infrastructure and drivers used by the system.

Reimplemented from CYIAsset.

const std::shared_ptr<CYIBitmap>& CYIAssetTexture::GetBitmap ( )

Returns the underlying bitmap associated with this texture asset. If the asset will be loaded if it is not currently loaded.

See also: CYIAsset::IsLoaded; CYIAsset::Load

virtual int32_t CYIAssetTexture::GetHeight ( ) const

overridevirtual

Returns the height of the underlying bitmap, in pixels. If the bitmap has not been set the height of the CYIAssetTextureBase will be returned, this is the cached height of the last bitmpa set on this texture asset.

See also: CYIBitmap::GetHeight

Reimplemented from CYIAssetTextureBase.

virtual int32_t CYIAssetTexture::GetWidth ( ) const

overridevirtual

Returns the width of the underlying bitmap, in pixels. If the bitmap is not available the width of the base CYIAssetTextureBase will be returned, this is the cached width of the last bitmap set on this texture asset.

See also: CYIBitmap::GetWidth

Reimplemented from CYIAssetTextureBase.

virtual void CYIAssetTexture::OnUnload ( )

overrideprotectedvirtual

Implements CYIAssetTextureBase.

void CYIAssetTexture::SetBitmap ( const std::shared_ptr< CYIBitmap > & pBitmap )

Sets a new bitmap on this texture asset using a shared pointer, pBitmap.

void CYIAssetTexture::SetBitmap ( std::unique_ptr< CYIBitmap > pBitmap )

Sets a new bitmap on this texture asset using a raw pointer, pBitmap.
