Constructor Detail

RowProducer

public RowProducer(ITransform transform,
                   IRowSet rowSet)

Method Detail

putRow

public void putRow(IRowMeta rowMeta,
                   Object[] row)

Puts a row into the underlying row set. This will block until the row is successfully added.

See Also:

putRow(IRowMeta, Object[], true)

putRow

public boolean putRow(IRowMeta rowMeta,
                      Object[] row,
                      boolean block)

Puts a row on to the underlying row set, optionally blocking until the row can be successfully put.

Returns:

true if the row was successfully added to the rowset and false if this buffer was full. If block is true this will always return true.

See Also:

IRowSet.putRow(IRowMeta, Object[])

putRowWait

public boolean putRowWait(IRowMeta rowMeta,
                          Object[] rowData,
                          long time,
                          TimeUnit tu)

See Also:

IRowSet.putRowWait(IRowMeta, Object[], long, TimeUnit)

finished

public void finished()

Signal that we are done producing rows. It will allow the transform to which this producer is attached to know that no more rows are forthcoming.

getRowSet

public IRowSet getRowSet()

Returns:

Returns the rowSet.

setRowSet

public void setRowSet(IRowSet rowSet)

Parameters:

rowSet - The rowSet to set.

getTransform

public ITransform getTransform()

Returns:

Returns the ITransform.

setTransform

public void setTransform(ITransform transform)

Parameters:

transform - The ITransform to set.
