Class PAssert.DefaultConcludeTransform

java.lang.Object

org.apache.beam.sdk.transforms.PTransform<PCollection<SuccessOrFailure>,PCollection<java.lang.Void>>

org.apache.beam.sdk.testing.PAssert.DefaultConcludeTransform

All Implemented Interfaces:

java.io.Serializable, HasDisplayData

Enclosing class:

PAssert

public static class PAssert.DefaultConcludeTransform
extends PTransform<PCollection<SuccessOrFailure>,PCollection<java.lang.Void>>

Default transform to check that a PAssert was successful. This transform relies on two Counter objects from the Metrics API to count the number of successful and failed asserts. Runners that do not support the Metrics API should replace this transform with their own implementation.

expand

public PCollection<java.lang.Void> expand(PCollection<SuccessOrFailure> 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).
