  • Method Details

    • withTikaConfigPath

      public TikaIO.ParseFiles withTikaConfigPath(String tikaConfigPath)
      Uses the given Tika Configuration XML file.

    • withTikaConfigPath

      public TikaIO.ParseFiles withTikaConfigPath(ValueProvider<String> tikaConfigPath)
      Like with(tikaConfigPath).

    • withContentTypeHint

      public TikaIO.ParseFiles withContentTypeHint(String contentTypeHint)
      Sets a content type hint to make the file parser detection more efficient. Overrides the content type hint in withInputMetadata(org.apache.tika.metadata.Metadata), if any.

    • withInputMetadata

      public TikaIO.ParseFiles withInputMetadata(org.apache.tika.metadata.Metadata metadata)
      Sets the input metadata for Parser.parse(java.io.InputStream, org.xml.sax.ContentHandler, org.apache.tika.metadata.Metadata, org.apache.tika.parser.ParseContext).

    • expand

      public PCollection<ParseResult> expand(PCollection<FileIO.ReadableFile> 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<FileIO.ReadableFile>,PCollection<ParseResult>>

    • 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<FileIO.ReadableFile>,PCollection<ParseResult>>
      Parameters:
      builder - The builder to populate with display data.
