ScriptGroup.Builder

public static final class ScriptGroup.Builder
extends Object

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

This class was deprecated in API level 23.
Use ScriptGroup.Builder2 instead.

Helper class to build a ScriptGroup. A ScriptGroup is created in two steps.

First, all kernels to be used by the ScriptGroup should be added.

Second, add connections between kernels. There are two types of connections: kernel to kernel and kernel to field. Kernel to kernel allows a kernel's output to be passed to another kernel as input. Kernel to field allows the output of one kernel to be bound as a script global. Kernel to kernel is higher performance and should be used where possible.

A ScriptGroup must contain a single directed acyclic graph (DAG); it cannot contain cycles. Currently, all kernels used in a ScriptGroup must come from different Script objects. Additionally, all kernels in a ScriptGroup must have at least one input, output, or internal connection.

Once all connections are made, a call to create() will return the ScriptGroup object.

Summary

Public constructors
`ScriptGroup.Builder(RenderScript rs)` Create a Builder for generating a ScriptGroup.

Public methods
`ScriptGroup.Builder`	`addConnection(Type t, Script.KernelID from, Script.FieldID to)` Adds a connection to the group.
`ScriptGroup.Builder`	`addConnection(Type t, Script.KernelID from, Script.KernelID to)` Adds a connection to the group.
`ScriptGroup.Builder`	`addKernel(Script.KernelID k)` Adds a Kernel to the group.
`ScriptGroup`	`create()` Creates the Script group.

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.

Public constructors

ScriptGroup.Builder

Added in API level 17

ScriptGroup.Builder (RenderScript rs)

Create a Builder for generating a ScriptGroup.

Parameters
`rs`	`RenderScript`: The RenderScript context.

Public methods

addConnection

Added in API level 17

ScriptGroup.Builder addConnection (Type t, 
                Script.KernelID from, 
                Script.FieldID to)

Adds a connection to the group.

Parameters
`t`	`Type`: The type of the connection. This is used to determine the kernel launch sizes on the source side of this connection.
`from`	`Script.KernelID`: The source for the connection.
`to`	`Script.FieldID`: The destination of the connection.

Returns

Added in API level 17

ScriptGroup.Builder addConnection (Type t, 
                Script.KernelID from, 
                Script.KernelID to)

Adds a connection to the group.

Parameters
`t`	`Type`: The type of the connection. This is used to determine the kernel launch sizes for both sides of this connection.
`from`	`Script.KernelID`: The source for the connection.
`to`	`Script.KernelID`: The destination of the connection.

Returns
`ScriptGroup.Builder`	Builder Returns this

addKernel

Added in API level 17

ScriptGroup.Builder addKernel (Script.KernelID k)

Adds a Kernel to the group.

Parameters
`k`	`Script.KernelID`: The kernel to add.

Returns
`ScriptGroup.Builder`	Builder Returns this.

create

Added in API level 17

ScriptGroup create ()
