Builder

class Builder
kotlin.Any
   ↳ android.renderscript.ScriptGroup.Builder

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.
