| * <p> This class provides the primary method through which data is passed to | |
| * and from RenderScript kernels. An Allocation provides the backing store for | |
| * a given {@link android.renderscript.Type}. </p> | |
| * | |
| * <p>An Allocation also contains a set of usage flags that denote how the | |
| * Allocation could be used. For example, an Allocation may have usage flags | |
| * specifying that it can be used from a script as well as input to a {@link | |
| * android.renderscript.Sampler}. A developer must synchronize across these | |
| * different usages using {@link android.renderscript.Allocation#syncAll} in | |
| * order to ensure that different users of the Allocation have a consistent view | |
| * of memory. For example, in the case where an Allocation is used as the output | |
| * of one kernel and as Sampler input in a later kernel, a developer must call | |
| * {@link #syncAll syncAll(Allocation.USAGE_SCRIPT)} prior to launching the | |
| * second kernel to ensure correctness. | |
| * | |
| * <p>An Allocation can be populated with the {@link #copyFrom} routines. For | |
| * more complex Element types, the {@link #copyFromUnchecked} methods can be | |
| * used to copy from byte arrays or similar constructs.</p> | |
