\brief BinaryKernel interface delegates to subclasses via Take()

Overrides:

Call in class BinaryKernel

out_type

@SharedPtr
 @Cast(value={"","std::shared_ptr<arrow::DataType>"})
public DataType out_type()

\brief output type of this kernel (identical to type of values taken)

Overrides:

out_type in class OpKernel

Returns:

the output type

Make

@ByVal
