    Description copied from class: Instruction
    
    This method should be used to execute the instruction.
    
    Specified by:
    
    processInstruction in class CPInstruction
    
    Parameters:
    
    ec - execution context
  - hasSingleLineage
```
public boolean hasSingleLineage()
```
    Description copied from interface: LineageTraceable
    
    Obtain meta data on number of outputs and thus, number of lineage items.
    
    Returns:
    
    true iff instruction has a single output
  - getLineageItems
```
public org.apache.commons.lang3.tuple.Pair<String,LineageItem>[] getLineageItems(ExecutionContext ec)
```
    Description copied from interface: LineageTraceable
    
    Obtain lineage trace of an instruction with multiple outputs.
    
    Parameters:
    
    ec - execution context w/ live variables
    
    Returns:
    
    pairs of (output variable name, output lineage item)
