/**
* <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>
