withConfiguration

public FileIO.MatchAll withConfiguration(FileIO.MatchConfiguration configuration)

Like FileIO.Match.withConfiguration(org.apache.beam.sdk.io.FileIO.MatchConfiguration).

withEmptyMatchTreatment

public FileIO.MatchAll withEmptyMatchTreatment(EmptyMatchTreatment treatment)

Like FileIO.Match.withEmptyMatchTreatment(org.apache.beam.sdk.io.fs.EmptyMatchTreatment).

public FileIO.MatchAll continuously(org.joda.time.Duration pollInterval,
                                    Watch.Growth.TerminationCondition<java.lang.String,?> terminationCondition,
                                    boolean matchUpdatedFiles)

                                    Watch.Growth.TerminationCondition<java.lang.String,?> terminationCondition)

Like FileIO.Match.continuously(Duration, TerminationCondition).

expand

public PCollection<MatchResult.Metadata> expand(PCollection<java.lang.String> input)

Description copied from class: PTransform

Override this method to specify how this PTransform should be expanded on the given InputT.

NOTE: This method should not be called directly. Instead apply the PTransform should be applied to the InputT using the apply method.

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).

Specified by:

expand in class PTransform<PCollection<java.lang.String>,PCollection<MatchResult.Metadata>>

populateDisplayData

public void populateDisplayData(DisplayData.Builder builder)

Description copied from class: PTransform

Register display data for the given transform or component.

populateDisplayData(DisplayData.Builder) is invoked by Pipeline runners to collect display data via DisplayData.from(HasDisplayData). Implementations may call super.populateDisplayData(builder) in order to register display data in the current namespace, but should otherwise use subcomponent.populateDisplayData(builder) to use the namespace of the subcomponent.

By default, does not register any display data. Implementors may override this method to provide their own display data.

Specified by:

populateDisplayData in interface HasDisplayData

Overrides:

populateDisplayData in class PTransform<PCollection<java.lang.String>,PCollection<MatchResult.Metadata>>

Parameters:

builder - The builder to populate with display data.
