Type

public class Type
extends BaseObj

java.lang.Object
   ↳ android.support.v8.renderscript.BaseObj
     ↳ android.support.v8.renderscript.Type


A Type describes the Element and dimensions used for an Allocation or a parallel operation. Types are created through Type.Builder.

A Type always includes an Element and an X dimension. A Type may be multidimensional, up to three dimensions. A nonzero value in the Y or Z dimensions indicates that the dimension is present. Note that a Type with only a given X dimension and a Type with the same X dimension but Y = 1 are not equivalent.

A Type also supports inclusion of level of detail (LOD) or cube map faces. LOD and cube map faces are booleans to indicate present or not present.

A Type also supports YUV format information to support an Allocation in a YUV format. The YUV formats supported are YV12 and NV21.
