An element represents one cell of a memory allocation. 24 * Element is the basic data type of Renderscript. An element can be of two forms: Basic elements or Complex forms. 25 * Examples of basic elements are:</p> 26 * <ul> 27 * <li>Single float value</li> 28 * <li>4 element float vector</li> 29 * <li>single RGB-565 color</li> 30 * <li>single unsigned int 16</li> 31 * </ul> 32 * <p>Complex elements contain a list of sub-elements and names that 33 * represents a structure of data. The fields can be accessed by name 34 * from a script or shader. The memory layout is defined and ordered. Data 35 * alignment is determined by the most basic primitive type. i.e. a float4 36 * vector will be aligned to sizeof(float) and not sizeof(float4). The 37 * ordering of elements in memory will be the order in which they were added 38 * with each component aligned as necessary. No re-ordering will be done.</p> 39 * 40 * <p>The primary source of elements are from scripts. A script that exports a 41 * bind point for a data structure generates a Renderscript element to represent the 42 * data exported by the script. The other common source of elements is from bitmap formats.</p> 43 **/ 44public class Element extends BaseObj { 45 int mSize; 46 Element[] mElements; 47 String[] mElementNames; 48 int[] mArraySizes; 49 int[] mOffsetInBytes; 50 51 int[] mVisibleElementMap; 52 53 DataType mType; 54 DataKind mKind; 55 boolean mNormalized; 56 int mVectorSize; 57 58 private void updateVisibleSubElements() { 59 if (mElements == null) { 60 return; 61 } 62 63 int noPaddingFieldCount = 0; 64 int fieldCount = mElementNames.length; 65 // Find out how many elements are not padding 66 for (int ct = 0; ct < fieldCount; ct ++) { 67 if (mElementNames[ct].charAt(0) != '#') { 68 noPaddingFieldCount ++; 69 } 70 } 71 mVisibleElementMap = new int[noPaddingFieldCount]; 72 73 // Make a map that points us at non-padding elements 74 for (int ct = 0, ctNoPadding = 0; ct < fieldCount; ct ++) { 75 if (mElementNames[ct].charAt(0) != '#') { 76 mVisibleElementMap[ctNoPadding ++] = ct; 77 } 78 } 79 } 80 81 /** 82 * @hide 83 * @return element size in bytes 84 */ 85 public int getSizeBytes() {return mSize;} 86 87 88 /** 89 * DataType represents the basic type information for a basic element.
