All Implemented Interfaces:

public class QuaternaryOp
extends MultiThreadedHop

Note: this hop should be called AggQuaternaryOp in consistency with AggUnaryOp and AggBinaryOp; however, since there does not exist a real QuaternaryOp yet - we can leave it as is for now.

Method Details

getOp

public Types.OpOp4 getOp()

isGPUEnabled

public boolean isGPUEnabled()

Description copied from class: Hop

In memory-based optimizer mode (see OptimizerUtils.isMemoryBasedOptLevel()), the exectype is determined by checking this method as well as memory budget of this Hop. Please see findExecTypeByMemEstimate for more detail. This method is necessary because not all operator are supported efficiently on GPU (for example: operations on frames and scalar as well as operations such as table).

Specified by:

isGPUEnabled in class Hop

Returns:

true if the Hop is eligible for GPU Exectype.

isMultiThreadedOpType

public boolean isMultiThreadedOpType()

Specified by:

isMultiThreadedOpType in class MultiThreadedHop

constructLops

public Lop constructLops()

Specified by:

constructLops in class Hop

getOpString

public String getOpString()

Specified by:

getOpString in class Hop

allowsAllExecTypes

public boolean allowsAllExecTypes()

Specified by:

allowsAllExecTypes in class Hop

refreshSizeInformation

public void refreshSizeInformation()

Description copied from class: Hop

Update the output size information for this hop.

Specified by:

refreshSizeInformation in class Hop

clone

public Object clone()
             throws CloneNotSupportedException

Specified by:

clone in class Hop

Throws:

CloneNotSupportedException

compare

public boolean compare(Hop that)

Specified by:

compare in class Hop
