Class AppliedPTransform<InputT extends PInput,OutputT extends POutput,TransformT extends PTransform<? super InputT,OutputT>>

java.lang.Object

org.apache.beam.sdk.runners.AppliedPTransform<InputT,OutputT,TransformT>

Type Parameters:

InputT - transform input type

OutputT - transform output type

TransformT - transform type

@Internal
public abstract class AppliedPTransform<InputT extends PInput,OutputT extends POutput,TransformT extends PTransform<? super InputT,OutputT>>
extends java.lang.Object

For internal use only; no backwards-compatibility guarantees.

Inputs and outputs are stored in their expanded forms, as the condensed form of a composite PInput or POutput is a language-specific concept, and AppliedPTransform represents a possibly cross-language transform for which no appropriate composite type exists in the Java SDK.
