Allocation

public class Allocation
extends BaseObj

java.lang.Object
   ↳ android.renderscript.BaseObj
     ↳ android.renderscript.Allocation
Known Direct Subclasses


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

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

Developer Guides

For more information about creating an application that uses RenderScript, read the RenderScript developer guide.

Summary

Nested classes

enum Allocation.MipmapControl

Controls mipmap behavior when using the bitmap creation and update functions. 

interface Allocation.OnBufferAvailableListener

Interface to handle notification when new buffers are available via USAGE_IO_INPUT

Constants

int USAGE_GRAPHICS_CONSTANTS

The Allocation will be used as the source of shader constants by one or more programs.

int USAGE_GRAPHICS_RENDER_TARGET

The Allocation will be used as a target for offscreen rendering This was deprecated in API level 16.

int USAGE_GRAPHICS_TEXTURE

The Allocation will be used as a texture source by one or more graphics programs.

int USAGE_GRAPHICS_VERTEX

The Allocation will be used as a graphics mesh.

int USAGE_IO_INPUT

The Allocation will be used as a Surface consumer.

int USAGE_IO_OUTPUT

The Allocation will be used as a Surface producer.

int USAGE_SCRIPT

The Allocation will be bound to and accessed by scripts.

int USAGE_SHARED

The Allocation's backing store will be inherited from another object (usually a Bitmap); copying to or from the original source Bitmap will cause a synchronization rather than a full copy.

void resize (int dimX)

This method was deprecated in API level 18.
RenderScript objects should be immutable once created. The replacement is to create a new allocation and copy the contents. This function will throw an exception if API 21 or higher is used.

Resize a 1D allocation. The contents of the allocation are preserved. If new elements are allocated objects are created with null contents and the new region is otherwise undefined.

If the new region is smaller the references of any objects outside the new region will be released.

A new type will be created with the new dimension.

Parameters
dimX int: The new size of the allocation.

setAutoPadding

Added in API level 23
void setAutoPadding (boolean useAutoPadding)

Specifies the mapping between the Allocation's cells and an array's elements when data is copied from the Allocation to the array, or vice-versa. Only applies to an Allocation whose Element is a vector of length 3 (such as U8_3(RenderScript) or RGB_888(RenderScript)). Enabling this feature may make copying data from the Allocation to an array or vice-versa less efficient.

Vec3 Element cells are stored in an Allocation as Vec4 Element cells with the same Element.DataType, with the fourth vector component treated as padding. When this feature is enabled, only the data components, i.e. the first 3 vector components of each cell, will be mapped between the array and the Allocation. When disabled, explicit mapping of the padding components is required, as described in the following example.

For example, when copying an integer array to an Allocation of two I32_3(RenderScript) cells using copyFrom(int[]):

When disabled: The array must have at least 8 integers, with the first 4 integers copied to the first cell of the Allocation, and the next 4 integers copied to the second cell. The 4th and 8th integers are mapped as the padding components.

When enabled: The array just needs to have at least 6 integers, with the first 3 integers copied to the the first cell as data components, and the next 3 copied to the second cell. There is no mapping for the padding components.

Similarly, when copying a byte array to an Allocation of two I32_3(RenderScript) cells, using copyFromUnchecked(int[]):

When disabled: The array must have at least 32 bytes, with the first 16 bytes copied to the first cell of the Allocation, and the next 16 bytes copied to the second cell. The 13th-16th and 29th-32nd bytes are mapped as padding components.

When enabled: The array just needs to have at least 24 bytes, with the first 12 bytes copied to the first cell of the Allocation, and the next 12 bytes copied to the second cell. There is no mapping for the padding components.

Similar to copying data to an Allocation from an array, when copying data from an Allocation to an array, the padding components for Vec3 Element cells will not be copied/mapped to the array if AutoPadding is enabled.

Default: Disabled.

Parameters
useAutoPadding boolean: True: enable AutoPadding; False: disable AutoPadding

Protected methods

finalize

Added in API level 11
void finalize ()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. A subclass overrides the finalize method to dispose of system resources or to perform other cleanup.

The general contract of finalize is that it is invoked if and when the JavaTM virtual machine has determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, except as a result of an action taken by the finalization of some other object or class which is ready to be finalized. The finalize method may take any action, including making this object available again to other threads; the usual purpose of finalize, however, is to perform cleanup actions before the object is irrevocably discarded. For example, the finalize method for an object that represents an input/output connection might perform explicit I/O transactions to break the connection before the object is permanently discarded.

The finalize method of class Object performs no special action; it simply returns normally. Subclasses of Object may override this definition.

The Java programming language does not guarantee which thread will invoke the finalize method for any given object. It is guaranteed, however, that the thread that invokes finalize will not be holding any user-visible synchronization locks when finalize is invoked. If an uncaught exception is thrown by the finalize method, the exception is ignored and finalization of that object terminates.

After the finalize method has been invoked for an object, no further action is taken until the Java virtual machine has again determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, including possible actions by other objects or classes which are ready to be finalized, at which point the object may be discarded.

The finalize method is never invoked more than once by a Java virtual machine for any given object.

Any exception thrown by the finalize method causes the finalization of this object to be halted, but is otherwise ignored.

Throws
Throwable
