Method Detail

execute

public FederatedResponse execute(ExecutionContext ec,
                                 Data... data)

Description copied from class: FederatedUDF

Execute the user-defined function on a set of data objects (e.g., matrix objects, frame objects, or scalars), which are looked up by specified input IDs and passed in the same order. Output data objects (potentially many) can be directly added to the passed execution context and its variable map.

Specified by:

execute in class FederatedUDF

Parameters:

ec - execution context

data - one or many data objects

Returns:

federated response, with none or many output objects

getOutputIds

public List<Long> getOutputIds()

Overrides:

getOutputIds in class FederatedUDF

getLineageItem

public org.apache.commons.lang3.tuple.Pair<String,LineageItem> getLineageItem(ExecutionContext ec)

Description copied from interface: LineageTraceable

Obtain lineage trace of an instruction with a single output.

Parameters:

ec - execution context w/ live variables

Returns:

pair of (output variable name, output lineage item)
