Class ParDo.UnboundMulti<O>

java.lang.Object

com.google.cloud.dataflow.sdk.transforms.ParDo.UnboundMulti<O>

Type Parameters:

O - the type of the main output PCollection elements

Enclosing class:

ParDo

public static class ParDo.UnboundMulti<O>
extends java.lang.Object

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

Before being applied, of(com.google.cloud.dataflow.sdk.transforms.DoFn<I, O>) must be invoked to specify the DoFn to invoke, which will also bind the input type of this PTransform.

Method Summary

Methods

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

Method Detail

named

public ParDo.UnboundMulti<O> named(java.lang.String name)

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

See the discussion of Naming above for more explanation.

withSideInputs

public ParDo.UnboundMulti<O> 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(com.google.cloud.dataflow.sdk.values.PCollectionView<?, ?>...) for more explanation.

withSideInputs

public ParDo.UnboundMulti<O> withSideInputs(java.lang.Iterable<? extends 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(com.google.cloud.dataflow.sdk.values.PCollectionView<?, ?>...) for more explanation.

of

public <I> ParDo.BoundMulti<I,O> of(DoFn<I,O> fn)

Returns a new multi-output ParDo PTransform that's like this transform but which will invoke the given DoFn 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.
