ScriptGroup.Closure

Kotlin |Java

public static final class ScriptGroup.Closure
extends BaseObj

java.lang.Object
↳	android.renderscript.BaseObj
	↳	android.renderscript.ScriptGroup.Closure

An opaque class for closures

A closure represents a function call to a kernel or invocable function, combined with arguments and values for global variables. A closure is created using the ScriptGroup.Builder2.addKernel(KernelID, Type, Object) or ScriptGroup.Builder2.addInvoke(InvokeID, Object) method.

Summary

Public methods
`void`	`destroy()` Destroys this Closure and the Allocation for its return value
`ScriptGroup.Future`	`getGlobal(Script.FieldID field)` Returns the future for a global variable
`ScriptGroup.Future`	`getReturn()` Returns the future for the return value

Protected methods
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

Inherited methods

`void`	`destroy()` Frees any native resources associated with this object.
`boolean`	`equals(Object obj)` Compare the current BaseObj with another BaseObj for equality.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`String`	`getName()`
`int`	`hashCode()` Calculates the hash code value for a BaseObj.

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(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(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()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Protected methods

finalize

Added in API level 23

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.

Throws
