Method Details

getOutput

public CPOperand getOutput(int i)

getOutputs

public List<CPOperand> getOutputs()

getOutputNames

public String[] getOutputNames()

parseInstruction

public static MultiReturnParameterizedBuiltinCPInstruction parseInstruction(String str)

processInstruction

public void processInstruction(ExecutionContext ec)

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)

getMetaReturn

public boolean getMetaReturn()
