Remarks

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 android.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 android.renderscript.Sampler. A developer must synchronize across these different usages using 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 #syncAll syncAll(Allocation.USAGE_SCRIPT) prior to launching the second kernel to ensure correctness.

An Allocation can be populated with the #copyFrom routines. For more complex Element types, the #copyFromUnchecked methods can be used to copy from byte arrays or similar constructs.
