§ dependencies()

template<class OperatorBase>

void TMBad::global::Complete< OperatorBase >::dependencies	(	Args<> &	args,
		Dependencies &	dep
	)

inlinevirtual

Get the indices of variables required by this operator.

Result of this operation (the indices) are appended to the dep argument. Its main purpose is to build the computational graph. Under normal circumstances the information can be autogenerated from the operator inputs. However there is a subtle exception: Operators are allowed to take reference inputs. For instance a matrix multiply only requires addresses of the first element of the two input matrices. Such cases must have special code to provide all input addresses.

Note: This information is somewhat overlapping with that of reverse(ReverseArgs<Replay>& args).
