property must be set:
targetPathName
|
WritePMML(String targetPathName)
Writes a PMML model to the given path

RecordPort#getSourceDataDistribution
and RecordPort#getSourceDataOrdering
. These should be
viewed as a hints to help chose a more efficient algorithm. In such cases, though, operators must
still declare data ordering and data distribution requirements; otherwise there is no guarantee that
data will arrive sorted/distributed as required.

.MergeModel
is a convenient, re-usable model reducer, parameterized with
a merge-handler.
SimpleModelPort
's have no associated metadata and therefore there is
never any output metadata to declare. PMMLPort
's, on the other hand,
do have associated metadata. For all PMMLPorts, implementations must declare
the following:
PMMLPort.setPMMLModelSpec
