    • Method Detail

      • apply

        public PCollection<KV<K,com.google.cloud.dataflow.sdk.util.WindowedValue<V>>> apply(PCollection<KV<K,V>> input)
        Description copied from class: PTransform
        Applies this PTransform on the given InputT, and returns its Output.

        Composite transforms, which are defined in terms of other transforms, should return the output of one of the composed transforms. Non-composite transforms, which do not apply any transforms internally, should return a new unbound output and register evaluators (via backend-specific registration methods).

        The default implementation throws an exception. A derived class must either implement apply, or else each runner must supply a custom implementation via PipelineRunner.apply(com.google.cloud.dataflow.sdk.transforms.PTransform<InputT, OutputT>, InputT).

        Overrides:
        apply in class PTransform<PCollection<KV<K,V>>,PCollection<KV<K,com.google.cloud.dataflow.sdk.util.WindowedValue<V>>>>
