getPipeline

public Pipeline getPipeline()

Description copied from interface: POutput

Returns the owning Pipeline of this POutput.

Specified by:

getPipeline in interface POutput

expand

public java.util.Map<TupleTag<?>,PValue> expand()

Description copied from interface: POutput

Expands this POutput into a list of its component output PValues.

• A PValue expands to itself.
• A tuple or list of PValues (such as PCollectionTuple or PCollectionList) expands to its component PValue PValues.

Not intended to be invoked directly by user code.

Specified by:

expand in interface POutput

finishSpecifyingOutput

public void finishSpecifyingOutput(java.lang.String transformName,
                                   PInput input,
                                   PTransform<?,?> transform)

Description copied from interface: POutput

As part of applying the producing PTransform, finalizes this output to make it ready for being used as an input and for running.

This includes ensuring that all PCollections have Coders specified or defaulted.

Automatically invoked whenever this POutput is output, after POutput.finishSpecifyingOutput(String, PInput, PTransform) has been called on each component PValue returned by POutput.expand().

Specified by:

finishSpecifyingOutput in interface POutput

getResults

public PCollection<Row> getResults()

Returns a PCollection containing the Rows that have been parsed.

getFailedToParseLines

public PCollection<Row> getFailedToParseLines()

Returns a PCollection containing the Rows that didn't parse.

If JsonToRow.JsonToRowWithErrFn.withExtendedErrorInfo() was set then the schema will also include the error message.
