EffectContext

extends Object

java.lang.Object
↳	android.media.effect.EffectContext

Class Overview

An EffectContext keeps all necessary state information to run Effects within a Open GL ES 2.0 context.

Every EffectContext is bound to one GL context. The application is responsible for creating this EGL context, and making it current before applying any effect. If your EGL context is destroyed, the EffectContext becomes invalid and any effects bound to this context can no longer be used. If you switch to another EGL context, you must create a new EffectContext. Each Effect is bound to a single EffectContext, and can only be executed in that context.

Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Public Methods

public static EffectContext createWithCurrentGlContext ()

Added in API level 14

Creates a context within the current GL context.

Binds the EffectContext to the current OpenGL context. All subsequent calls to the EffectContext must be made in the GL context that was active during creation. When you have finished using a context, you must call release(). to dispose of all resources associated with this context.

public EffectFactory getFactory ()

Added in API level 14

Returns the EffectFactory for this context.

The EffectFactory returned from this method allows instantiating new effects within this context.

Returns

The EffectFactory instance for this context.

public void release ()

Added in API level 14

Releases the context.

Releases all the resources and effects associated with the EffectContext. This renders the context and all the effects bound to this context invalid. You must no longer use the context or any of its bound effects after calling release().

Note that this method must be called with the proper EGL context made current, as the EffectContext and its effects may release internal GL resources.
