void CppAD::local::subgraph::subgraph_info::init_rev	(	const player< Base > *	play,
		const BoolVector &	select_domain
	)

Initialize in_subgraph corresponding to a single dependent variable (and a selected set of independent variables).

Template Parameters

Base	this operation sequence was recording using AD<Base>.

Parameters

play	is the operation sequence corresponding to the ADFun<Base> function (it must correspond to map_user_op_).
select_domain	is a vector with, size equal to the number of independent variables in the recording. It determines the selected independent variables.

in_subgraph_: We use depend_yes (depend_no) for the value n_dep_ (n_dep_ + 1). The important properties are that depend_yes < depend_no and for a valid indpendent variable index i_ind < depend_yes. The input size and elements of in_subgraph_ do not matter. If in_subgraph_[i_op] == depend_yes (depend_no), the result for this operator depends (does not depend) on the selected independent variables. Note that for user function call operators i_op, in_subgraph[i_op] is depend_no except for the first UserOp in the atomic function call sequence. For the first UserOp, it is depend_yes (depend_no) if any of the results for the call sequence depend (do not depend) on the selected independent variables. Except for UserOP, only operators with NumRes(op) > 0 have in_subgraph_ value depend_yes; e.g., comparision operators have in_subgraph_ value depend_no.

process_range_: This vector is to to size n_dep_ and its values are set to false
