| /** |
| * <p> |
| * Memory allocation class for renderscript. An allocation combines a |
| * {@link android.renderscript.Type} with the memory to provide storage for user data and objects. |
| * This implies that all memory in Renderscript is typed. |
| * </p> |
| * |
| * <p>Allocations are the primary way data moves into and out of scripts. Memory is user |
| * synchronized and it's possible for allocations to exist in multiple memory spaces |
| * concurrently. Currently those spaces are:</p> |
| * <ul> |
| * <li>Script: accessable by RS scripts.</li> |
| * <li>Graphics Texture: accessable as a graphics texture.</li> |
| * <li>Graphics Vertex: accessable as graphical vertex data.</li> |
| * <li>Graphics Constants: Accessable as constants in user shaders</li> |
| * </ul> |
| * </p> |
| * <p> |
| * For example, when creating a allocation for a texture, the user can |
| * specify its memory spaces as both script and textures. This means that it can both |
| * be used as script binding and as a GPU texture for rendering. To maintain |
| * synchronization if a script modifies an allocation used by other targets it must |
| * call a synchronizing function to push the updates to the memory, otherwise the results |
| * are undefined. |
| * </p> |
| * <p>By default, Android system side updates are always applied to the script accessable |
| * memory. If this is not present, they are then applied to the various HW |
| * memory types. A {@link android.renderscript.Allocation#syncAll syncAll()} |
| * call is necessary after the script data is updated to |
| * keep the other memory spaces in sync.</p> |
| * |
| * <p>Allocation data is uploaded in one of two primary ways. For simple |
| * arrays there are copyFrom() functions that take an array from the control code and |
| * copy it to the slave memory store. Both type checked and unchecked copies are provided. |
| * The unchecked variants exist to allow apps to copy over arrays of structures from a |
| * control language that does not support structures.</p> |
