# RenderScript.RSMessageHandler

*** ** * ** ***

` public static class RenderScript.RSMessageHandler `   
` extends https://developer.android.com/reference/java/lang/Object ` ` implements https://developer.android.com/reference/java/lang/Runnable `

|---|---|
| [java.lang.Object](https://developer.android.com/reference/java/lang/Object) ||
| ↳ | android.renderscript.RenderScript.RSMessageHandler |

<br />

*** ** * ** ***

The base class from which an application should derive in order to receive RS messages from scripts. When a script calls `rsSendToClient`, the data fields will be filled, and the run method will be called on a separate thread. This will occur some time after `rsSendToClient` completes in the script, as `rsSendToClient` is asynchronous. Message handlers are not guaranteed to have completed when `https://developer.android.com/reference/android/renderscript/RenderScript#finish()` returns.

### Inherited methods

From class ` https://developer.android.com/reference/java/lang/Object ` ` https://developer.android.com/reference/java/lang/Object` ` https://developer.android.com/reference/java/lang/Object#clone()() `

Creates and returns a copy of this object.
` boolean` ` https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)(https://developer.android.com/reference/java/lang/Object obj) `

Indicates whether some other object is "equal to" this one.
` void` ` https://developer.android.com/reference/java/lang/Object#finalize()() `

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
` final https://developer.android.com/reference/java/lang/Class<?>` ` https://developer.android.com/reference/java/lang/Object#getClass()() `

Returns the runtime class of this `Object`.
` int` ` https://developer.android.com/reference/java/lang/Object#hashCode()() `

Returns a hash code value for the object.
` final void` ` https://developer.android.com/reference/java/lang/Object#notify()() `

Wakes up a single thread that is waiting on this object's monitor.
` final void` ` https://developer.android.com/reference/java/lang/Object#notifyAll()() `

Wakes up all threads that are waiting on this object's monitor.
` https://developer.android.com/reference/java/lang/String` ` https://developer.android.com/reference/java/lang/Object#toString()() `

Returns a string representation of the object.
` final void` ` https://developer.android.com/reference/java/lang/Object#wait(long,%20int)(long timeoutMillis, int nanos) `

Causes the current thread to wait until it is awakened, typically by being *notified* or *interrupted*, or until a certain amount of real time has elapsed.
` final void` ` https://developer.android.com/reference/java/lang/Object#wait(long)(long timeoutMillis) `

Causes the current thread to wait until it is awakened, typically by being *notified* or *interrupted*, or until a certain amount of real time has elapsed.
` final void` ` https://developer.android.com/reference/java/lang/Object#wait()() `

Causes the current thread to wait until it is awakened, typically by being *notified* or *interrupted*.
From interface ` https://developer.android.com/reference/java/lang/Runnable ` ` abstract void` ` https://developer.android.com/reference/java/lang/Runnable#run()() `

When an object implementing interface `Runnable` is used to create a thread, starting the thread causes the object's `run` method to be called in that separately executing thread.

## Public methods

### run

Added in [API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public void run ()

The general contract of the method `run` is that it may take any action whatsoever.
