Class Overview

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.

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

Adds a connection to the group.

Parameters
t The type of the connection. This is used to determine the kernel launch sizes on the source side of this connection.
from The source for the connection.
to The destination of the connection.
Returns

public ScriptGroup.Builder addKernel (Script.KernelID k)

Adds a Kernel to the group.

Parameters
k The kernel to add.
Returns
ScriptGroup.Builder Builder Returns this.

public ScriptGroup create ()

Creates the Script group.

Returns
ScriptGroup ScriptGroup The new ScriptGroup
