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.support.v8.renderscript.Type}.

* *

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.support.v8.renderscript.Sampler}. A developer must synchronize * across these different usages using * {@link android.support.v8.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. * *

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.
