| * <p>An Element represents one item within an {@link |
| * android.renderscript.Allocation}. An Element is roughly equivalent to a C |
| * type in a RenderScript kernel. Elements may be basic or complex. Some basic |
| * elements are</p> <ul> <li>A single float value (equivalent to a float in a |
| * kernel)</li> <li>A four-element float vector (equivalent to a float4 in a |
| * kernel)</li> <li>An unsigned 32-bit integer (equivalent to an unsigned int in |
| * a kernel)</li> <li>A single signed 8-bit integer (equivalent to a char in a |
| * kernel)</li> </ul> <p>A complex element is roughly equivalent to a C struct |
| * and contains a number of basic or complex Elements. From Java code, a complex |
| * element contains a list of sub-elements and names that represents a |
| * particular data structure. Structs used in RS scripts are available to Java |
| * code by using the {@code ScriptField_structname} class that is reflected from |
| * a particular script.</p> |
| * |
| * <p>Basic Elements are comprised of a {@link |
| * android.renderscript.Element.DataType} and a {@link |
| * android.renderscript.Element.DataKind}. The DataType encodes C type |
| * information of an Element, while the DataKind encodes how that Element should |
| * be interpreted by a {@link android.renderscript.Sampler}. Note that {@link |
| * android.renderscript.Allocation} objects with DataKind {@link |
| * android.renderscript.Element.DataKind#USER} cannot be used as input for a |
| * {@link android.renderscript.Sampler}. In general, {@link |
| * android.renderscript.Allocation} objects that are intended for use with a |
| * {@link android.renderscript.Sampler} should use bitmap-derived Elements such |
| * as {@link android.renderscript.Element#RGBA_8888} or {@link |
| * android.renderscript#Element.A_8}.</p> |
