Constructor Detail

Dummy

public Dummy(TransformMeta transformMeta,
             DummyMeta meta,
             DummyData data,
             int copyNr,
             PipelineMeta pipelineMeta,

Method Detail

processRow

public boolean processRow()
                   throws HopException

Description copied from interface: ITransform

Perform the equivalent of processing one row. Typically this means reading a row from input (getRow()) and passing a row to output (putRow)).

Specified by:

processRow in interface ITransform

Overrides:

processRow in class BaseTransform<DummyMeta,DummyData>

Returns:

false if no more rows can be processed or an error occurred.

Throws:

HopException
