Class Overview

Program is a base class for all the objects that modify various stages of the graphics pipeline

Summary

Nested Classes
class Program.BaseProgramBuilder  
enum Program.TextureType TextureType specifies what textures are attached to Program objects  
Public Methods
void bindConstants(Allocation a, int slot)
Binds a constant buffer to be used as uniform inputs to the program
void bindSampler(Sampler vs, int slot)
Binds an object that describes how a texture at the corresponding location is sampled
void bindTexture(Allocation va, int slot)
Binds a texture to be used in the program
synchronized void destroy()
destroy disconnects the object from the native object effectively rendering this java object dead.
void setName(String name)
setName assigns a name to an object.
Protected Methods
void finalize()
Called before the object's memory is reclaimed by the VM.

Inherited Methods

Public Methods

public void bindConstants (Allocation a, int slot)

Since: API Level 11

Binds a constant buffer to be used as uniform inputs to the program

Parameters
a allocation containing uniform data
slot index within the program's list of constant buffer allocations

public void bindSampler (Sampler vs, int slot)

Since: API Level 11

Binds an object that describes how a texture at the corresponding location is sampled

Parameters
vs sampler for a corresponding texture
slot index within the program's list of textures to use the sampler on
Throws
IllegalArgumentException

public void bindTexture (Allocation va, int slot)

Since: API Level 11

Binds a texture to be used in the program

Parameters
va allocation containing texture data
slot index within the program's list of textures
Throws
IllegalArgumentException

public synchronized void destroy ()

Since: API Level 11

destroy disconnects the object from the native object effectively rendering this java object dead. The primary use is to force immediate cleanup of resources when it is believed the GC will not respond quickly enough.

public void setName (String name)

Since: API Level 11

setName assigns a name to an object. This object can later be looked up by this name. This name will also be retained if the object is written to an A3D file.

Parameters
name The name to assign to the object.

Protected Methods

protected void finalize ()

Since: API Level 11

Called before the object's memory is reclaimed by the VM. This can only happen once the garbage collector has detected that the object is no longer reachable by any thread of the running application.

The method can be used to free system resources or perform other cleanup before the object is garbage collected. The default implementation of the method is empty, which is also expected by the VM, but subclasses can override finalize() as required. Uncaught exceptions which are thrown during the execution of this method cause it to terminate immediately but are otherwise ignored.

Note that the VM does guarantee that finalize() is called at most once for any object, but it doesn't guarantee when (if at all) finalize() will be called. For example, object B's finalize() can delay the execution of object A's finalize() method and therefore it can delay the reclamation of A's memory. To be safe, use a ReferenceQueue, because it provides more control over the way the VM deals with references during garbage collection.

Throwable
