ScriptGroup.Builder2

public static final class ScriptGroup.Builder2
extends Object

java.lang.Object
↳	android.renderscript.ScriptGroup.Builder2

The builder class for creating script groups

A script group is created using closures (see class ScriptGroup.Closure). A closure is a function call to a kernel or invocable function. Each function argument or global variable accessed inside the function is bound to 1) a known value, 2) a script group input (see class ScriptGroup.Input), or 3) a future (see class ScriptGroup.Future). A future is the output of a closure, either the return value of the function or a global variable written by that function.

Closures are created using the addKernel(Script.KernelID, Type, Object...) or addInvoke(Script.InvokeID, Object...) methods. When a closure is created, futures from previously created closures can be used as its inputs. External script group inputs can be used as inputs to individual closures as well. An external script group input is created using the addInput() method. A script group is created by a call to the create(String, ScriptGroup.Future...) method, which accepts an array of futures as the outputs for the script group.

Closures in a script group can be evaluated in any order as long as the following conditions are met: 1) a closure must be evaluated before any other closures that take its futures as inputs; 2) all closures added before an invoke closure must be evaluated before it; and 3) all closures added after an invoke closure must be evaluated after it. As a special case, the order that the closures are added is a legal evaluation order. However, other evaluation orders are possible, including concurrently evaluating independent closures.

Inherited methods

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 millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
