+ * across these different usages using

+ * 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

+ * {@link #syncAll syncAll(Allocation.USAGE_SCRIPT)} prior to launching the
+ * second kernel to ensure correctness.

+ *
+ * <p> Similarly, when copying a byte array to an Allocation of two {@link
+ * Element#I32_3} cells, using {@link #copyFromUnchecked(int[])}:
+ * <p> 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.
+ *
+ * <p> 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.
+ *
+ * <p> Similar to copying data to an Allocation from an array, when copying data from an

+ * (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
+ * androidx.renderscript.Element.DataType} and a {@link
+ * androidx.renderscript.Element.DataKind}. The DataType encodes C
+ * type information of an Element, while the DataKind encodes how that Element
