An Element represents one item within an Allocation. An Element is roughly equivalent to a C
type in a RenderScript kernel. Elements may be basic or complex. Some basic
elements are
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 ScriptField_structname class that is reflected from
a particular script.
Basic Elements are comprised of a Element.DataType and a Element.DataKind. The DataType encodes C type
information of an Element, while the DataKind encodes how that Element should
be interpreted by a Sampler. Note that Allocation objects with DataKind Element.DataKind.USER cannot be used as input for a
Sampler. In general, Allocation objects that are intended for use with a
Sampler should use bitmap-derived Elements such
as RGBA_8888(RenderScript) or A_8(RenderScript).
For more information about creating an application that uses RenderScript, read the RenderScript developer guide.
classElement.Builder
Builder class for producing complex elements with matching field and name pairs.

| Parameters | |
|---|---|
index |
int: index of the sub-element to return |
| Returns | |
|---|---|
Element |
sub-element in this element at given index |
public int getSubElementArraySize (int index)
For complex elements, some sub-elements could be statically sized arrays. This function will return the array size for sub-element at index
| Parameters | |
|---|---|
index |
int: index of the sub-element |
| Returns | |
|---|---|
int |
array size of sub-element in this element at given index |
public int getSubElementCount ()
Elements could be simple, such as an int or a float, or a structure with multiple sub elements, such as a collection of floats, float2, float4. This function returns zero for simple elements or the number of sub-elements otherwise.
| Returns | |
|---|---|
int |
number of sub-elements in this element |
public String getSubElementName (int index)
For complex elements, this function will return the sub-element name at index
| Parameters | |
|---|---|
index |
int: index of the sub-element |
| Returns | |
|---|---|
String |
sub-element in this element at given index |
public int getSubElementOffsetBytes (int index)
This function specifies the location of a sub-element within the element
| Parameters | |
|---|---|
index |
int: index of the sub-element |
| Returns | |
|---|---|
int |
offset in bytes of sub-element in this element at given index |
public int getVectorSize ()
Returns the number of vector components. 2 for float2, 4 for float4, etc.
| Returns | |
|---|---|
int |
element vector size |
public boolean isCompatible (Element e)
Check if the current Element is compatible with another Element. Primitive Elements are compatible if they share the same underlying size and type (i.e. U8 is compatible with A_8). User-defined Elements must be equal in order to be compatible. This requires strict name equivalence for all sub-Elements (in addition to structural equivalence).
| Parameters | |
|---|---|
e |
Element: The Element to check compatibility with. |
| Returns | |
|---|---|
boolean |
boolean true if the Elements are compatible, otherwise false. |
