**This class was deprecated in API level 31.** Renderscript has been deprecated in API level 31. Please refer to the[migration guide](https://developer.android.com/guide/topics/renderscript/migration-guide)for the proposed alternatives. BaseObj is the base class for all RenderScript objects owned by a RS context. It is responsible for lifetime management and resource tracking. This class should not be used by a user application. ## Summary | ### Public methods || |-----------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | ` void` | ` `[destroy](https://developer.android.com/reference/android/renderscript/BaseObj#destroy())`() ` Frees any native resources associated with this object. | | ` boolean` | ` `[equals](https://developer.android.com/reference/android/renderscript/BaseObj#equals(java.lang.Object))`(`[Object](https://developer.android.com/reference/java/lang/Object)` obj) ` Compare the current BaseObj with another BaseObj for equality. | | ` `[String](https://developer.android.com/reference/java/lang/String) | ` `[getName](https://developer.android.com/reference/android/renderscript/BaseObj#getName())`() ` | | ` int` | ` `[hashCode](https://developer.android.com/reference/android/renderscript/BaseObj#hashCode())`() ` Calculates the hash code value for a BaseObj. | | ` void` | ` `[setName](https://developer.android.com/reference/android/renderscript/BaseObj#setName(java.lang.String))`(`[String](https://developer.android.com/reference/java/lang/String)` name) ` setName assigns a name to an object. | | ### Protected methods || |---------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | ` void` | ` `[finalize](https://developer.android.com/reference/android/renderscript/BaseObj#finalize())`() ` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. | | ### Inherited methods | |-----------------------|---| | From class` `[java.lang.Object](https://developer.android.com/reference/java/lang/Object)` ` |--------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | ` `[Object](https://developer.android.com/reference/java/lang/Object) | ` `[clone](https://developer.android.com/reference/java/lang/Object#clone())`() ` Creates and returns a copy of this object. | | ` boolean` | ` `[equals](https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object))`(`[Object](https://developer.android.com/reference/java/lang/Object)` obj) ` Indicates whether some other object is "equal to" this one. | | ` void` | ` `[finalize](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 `[Class](https://developer.android.com/reference/java/lang/Class)`` | ` `[getClass](https://developer.android.com/reference/java/lang/Object#getClass())`() ` Returns the runtime class of this`Object`. | | ` int` | ` `[hashCode](https://developer.android.com/reference/java/lang/Object#hashCode())`() ` Returns a hash code value for the object. | | ` final void` | ` `[notify](https://developer.android.com/reference/java/lang/Object#notify())`() ` Wakes up a single thread that is waiting on this object's monitor. | | ` final void` | ` `[notifyAll](https://developer.android.com/reference/java/lang/Object#notifyAll())`() ` Wakes up all threads that are waiting on this object's monitor. | | ` `[String](https://developer.android.com/reference/java/lang/String) | ` `[toString](https://developer.android.com/reference/java/lang/Object#toString())`() ` Returns a string representation of the object. | | ` final void` | ` `[wait](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` | ` `[wait](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` | ` `[wait](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*. | || ## Public methods ### destroy Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void destroy () ``` Frees any native resources associated with this object. The primary use is to force immediate cleanup of resources when it is believed the GC will not respond quickly enough.
### equals Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public boolean equals (Object obj) ``` Compare the current BaseObj with another BaseObj for equality.
| Parameters || |-------|-----------------------------------------------------| | `obj` | `Object`: The object to check equality with.
| | Returns || |-----------|----------------| | `boolean` | boolean
| ### getName Added in[API level 14](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) Deprecated in[API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public String getName () ```

| Returns || |--------------------------------------------------------------------|----------------------------------------| | [String](https://developer.android.com/reference/java/lang/String) | name of the renderscript object
| ### hashCode Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public int hashCode () ``` Calculates the hash code value for a BaseObj.
| Returns || |-------|------------| | `int` | int
| ### setName Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void setName (String name) ``` setName assigns a name to an object. This object can later be looked up by this name.
| Parameters || |--------|----------------------------------------------------| | `name` | `String`: The name to assign to the object.
| ## Protected methods ### finalize Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` protected void finalize () ``` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. A subclass overrides the`finalize`method to dispose of system resources or to perform other cleanup. The general contract of`finalize`is that it is invoked if and when the Java virtual machine has determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, except as a result of an action taken by the finalization of some other object or class which is ready to be finalized. The`finalize`method may take any action, including making this object available again to other threads; the usual purpose of`finalize`, however, is to perform cleanup actions before the object is irrevocably discarded. For example, the finalize method for an object that represents an input/output connection might perform explicit I/O transactions to break the connection before the object is permanently discarded. The`finalize`method of class`Object`performs no special action; it simply returns normally. Subclasses of`Object`may override this definition. The Java programming language does not guarantee which thread will invoke the`finalize`method for any given object. It is guaranteed, however, that the thread that invokes finalize will not be holding any user-visible synchronization locks when finalize is invoked. If an uncaught exception is thrown by the finalize method, the exception is ignored and finalization of that object terminates. After the`finalize`method has been invoked for an object, no further action is taken until the Java virtual machine has again determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, including possible actions by other objects or classes which are ready to be finalized, at which point the object may be discarded. The`finalize`method is never invoked more than once by a Java virtual machine for any given object. Any exception thrown by the`finalize`method causes the finalization of this object to be halted, but is otherwise ignored.
