Constructor & Destructor Documentation

coco::dag_delta::dag_delta	(	const std::string &	__a,
		bool	full = false
	)			[inline]

Constructor setting the action identifier to __a and the is_full_delta member to full.

Definition at line 185 of file dag_delta.h.

coco::dag_delta::dag_delta	(	const std::string &	__a,
		model *	__nc,
		bool	full = false
	)			[inline]

Constructor setting the action identifier to __a and the is_full_delta member to full. Furthermore, the new_constraints member is initialized with __nc.

Member Function Documentation

void coco::dag_delta::add_new

(

model &

__m

)

[inline]

This method initializes the new_constraints member.

Definition at line 233 of file dag_delta.h.

void coco::dag_delta::add_new

(

model *

__m

)

[inline]

This method initializes the new_constraints member.

Definition at line 228 of file dag_delta.h.

bool coco::dag_delta::apply	(	work_node &	x,
		undelta_base *&	_u,
		const delta_id &	_did
	)			const [virtual]

Apply the delta with delta_id _d to work node _x, hereby changing the bounds as requested.

save node numbers corresponding to the various new things

Reimplemented from coco::delta_base.

Definition at line 110 of file dag_delta.cc.

bool coco::delta_base::apply3	(	work_node &	_x,
		const work_node &	_y,
		undelta_base *&	_u,
		const delta_id &	_d
	)			const [inline, virtual, inherited]

Apply the delta with delta_id _d to work node _x, constructing in the process work_node _y, without changing _x. In this process the undo information for this delta is stored in _u. This method should be overloaded in the specializations of this class for maximal efficiency, but it need not since a standard procedure is available, which uses the work_node copy constructur and the apply method.

Definition at line 88 of file api_delta.h.

virtual void coco::delta_base::convert	(	work_node &	_x,
		delta_base *&	_d
	)			[inline, virtual, inherited]

Convert this delta to a delta which can be stored in _x, this is e.g. used for all delta version, which are actually stored as annotation changes.

Reimplemented in coco::table_delta.

Member Data Documentation

std::string coco::delta_base::_action [protected, inherited]

The action (type) of this delta

Definition at line 154 of file api_deltabase.h.

bool coco::dag_delta::is_full_delta

If this variable is true, the new_constraints member contains a full model, which is used to replace the model of the work_node when the delta is applied.

Definition at line 181 of file dag_delta.h.

counted_ptr<model> coco::dag_delta::new_constraints

This DAG will be added to the DAG of the work node when applied. The ghost nodes in this DAG are used to overlay the nodes with the same node number in the original DAG.

Definition at line 170 of file dag_delta.h.

std::vector<walker> coco::dag_delta::rm_nodes

This variable holds the nodes which are to be removed from the work node DAG. Actually, the minimal subgraph generated by the nodes is removed, i.e. the subgraph containing all nodes in rm_nodes and all nodes, which are only connected to them.
