Class ParDo.UnboundMulti<OutputT>

java.lang.Object

org.apache.beam.sdk.transforms.ParDo.UnboundMulti<OutputT>

Type Parameters:

OutputT - the type of the main output PCollection elements

Enclosing class:

ParDo

public static class ParDo.UnboundMulti<OutputT>
extends Object

An incomplete multi-output ParDo transform, with unbound input type.

Before being applied, of(org.apache.beam.sdk.transforms.DoFn<InputT, OutputT>) must be invoked to specify the DoFn to invoke, which will also bind the input type of this PTransform.

Method Summary

Modifier and Type	Method and Description
<InputT> ParDo.BoundMulti<InputT,OutputT>	of(DoFn<InputT,OutputT> fn) Returns a new multi-output ParDo PTransform that's like this transform but that will invoke the given DoFn function, and that has its input type bound.
<InputT> ParDo.BoundMulti<InputT,OutputT>	of(DoFn<InputT,OutputT> fn, Class<?> fnClass)
<InputT> ParDo.BoundMulti<InputT,OutputT>	of(DoFnWithContext<InputT,OutputT> fn) Returns a new multi-output ParDo PTransform that's like this transform but which will invoke the given DoFnWithContext function, and which has its input type bound.
ParDo.UnboundMulti<OutputT>	withSideInputs(Iterable<? extends PCollectionView<?>> sideInputs) Returns a new multi-output ParDo transform that's like this transform but with the specified additional side inputs.
ParDo.UnboundMulti<OutputT>	withSideInputs(PCollectionView<?>... sideInputs) Returns a new multi-output ParDo transform that's like this transform but with the specified side inputs.

Method Detail

withSideInputs

public ParDo.UnboundMulti<OutputT> withSideInputs(PCollectionView<?>... sideInputs)

Returns a new multi-output ParDo transform that's like this transform but with the specified side inputs. Does not modify this transform. The resulting transform is still incomplete.

See the discussion of Side Inputs above and on ParDo.withSideInputs(org.apache.beam.sdk.values.PCollectionView<?>...) for more explanation.

withSideInputs

public ParDo.UnboundMulti<OutputT> withSideInputs(Iterable<? extends PCollectionView<?>> sideInputs)

Returns a new multi-output ParDo transform that's like this transform but with the specified additional side inputs. Does not modify this transform. The resulting transform is still incomplete.

See the discussion of Side Inputs above and on ParDo.withSideInputs(org.apache.beam.sdk.values.PCollectionView<?>...) for more explanation.

of

public <InputT> ParDo.BoundMulti<InputT,OutputT> of(DoFn<InputT,OutputT> fn)

Returns a new multi-output ParDo PTransform that's like this transform but that will invoke the given DoFn function, and that has its input type bound. Does not modify this transform. The resulting PTransform is sufficiently specified to be applied, but more properties can still be specified.

of

public <InputT> ParDo.BoundMulti<InputT,OutputT> of(DoFnWithContext<InputT,OutputT> fn)

Returns a new multi-output ParDo PTransform that's like this transform but which will invoke the given DoFnWithContext function, and which has its input type bound. Does not modify this transform. The resulting PTransform is sufficiently specified to be applied, but more properties can still be specified.
