Method Detail- 
checkAritypublic void checkArity() Description copied from class:HopCheck whether this Hop has a correct number of inputs. (Some Hops can have a variable number of inputs, such as DataOp, DataGenOp, ParameterizedBuiltinOp, ReorgOp, TernaryOp, QuaternaryOp, MultipleOp, DnnOp, and SpoofFusedOp.) Parameterized Hops (such as DataOp) can check that the number of parameters matches the number of inputs.- Specified by:
- checkArityin class- Hop
 
 - 
isGPUEnabledpublic boolean isGPUEnabled() Description copied from class:HopIn 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:
- isGPUEnabledin class- Hop
- Returns:
- true if the Hop is eligible for GPU Exectype.

 - 
refreshSizeInformationpublic void refreshSizeInformation() Description copied from class:HopUpdate the output size information for this hop.- Specified by:
- refreshSizeInformationin class- Hop
