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)
