Constructor Detail- 
NaryOppublic NaryOp(String name, Types.DataType dataType, Types.ValueType valueType, Types.OpOpN op, Hop... inputs) NaryOp constructor.- Parameters:
- name- the target name, typically set by the DMLTranslator when constructing Hops. (For example, 'parsertemp1'.)
- dataType- the target data type (SCALAR for printf)
- valueType- the target value type (STRING for printf)
- op- the operation type (such as PRINTF)
- inputs- a variable number of input Hops

Method Detail- 
checkAritypublic void checkArity() MultipleOp may have any number of inputs.- Specified by:
- checkArityin class- Hop
 
 - 
getOppublic Types.OpOpN getOp() 
 - 
getOpStringpublic String getOpString() - Specified by:
- getOpStringin 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.
 
 - 
constructLopspublic Lop constructLops() Construct the corresponding Lops for this Hop- Specified by:
- constructLopsin class- Hop
 
 - 
allowsAllExecTypespublic boolean allowsAllExecTypes() - Specified by:
- allowsAllExecTypesin class- Hop
 
 - 
computeMemEstimatepublic void computeMemEstimate(MemoTable memo) Description copied from class:HopComputes the estimate of memory required to store the input/output of this hop in memory. This is the default implementation (orchestration of hop-specific implementation) that should suffice for most hops. If a hop requires more control, this method should be overwritten with awareness of (1) output estimates, and (2) propagation of worst-case matrix characteristics (dimensions, sparsity). TODO remove memo table and, on constructor refresh, inference in refresh, single compute mem, maybe general computeMemEstimate, flags to indicate if estimate or not.- Overrides:
- computeMemEstimatein class- Hop
- Parameters:
- memo- memory table
 
 - 
refreshSizeInformationpublic void refreshSizeInformation() Description copied from class:HopUpdate the output size information for this hop.- Specified by:
- refreshSizeInformationin class- Hop
 
 - 
clonepublic Object clone() throws CloneNotSupportedException - Specified by:
- clonein class- Hop
- Throws:
- CloneNotSupportedException
