Method Detail

withCoder

public Create.TimestampedValues<T> withCoder(Coder<T> coder)

Returns a Create.TimestampedValues PTransform like this one that uses the given Coder<T> to decode each of the objects into a value of type T.

By default, Create.TimestampedValues can automatically determine the Coder to use if all elements have the same non-parameterized run-time class, and a default coder is registered for that class. See CoderRegistry for details on how defaults are determined.

Note that for with no elements, the VoidCoder is used.

apply

public PCollection<T> apply(PInput 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).
