Detailed Description

A base delta class which provides all functionality to add information to the search database. It is, after storing the information in the search database, converted to an annotation_delta. Therefore, no table_undelta class is needed.

Definition at line 43 of file table_delta.h.

Member Typedef Documentation

typedef std::vector<t_line> coco::table_delta::t_ctr

A variable of this type holds the new table entries.

Definition at line 49 of file table_delta.h.

typedef std::pair<std::string,dbt_row> coco::table_delta::t_line

This type specifies one row in one table.

Definition at line 47 of file table_delta.h.

Constructor & Destructor Documentation

coco::table_delta::table_delta ( const std::string & a ) [inline]

Standard Constructor, which sets the action descriptor a

Definition at line 59 of file table_delta.h.

coco::table_delta::table_delta	(	const std::string &	a,
		const t_ctr &	_n,
		const std::vector< annotation > &	_r
	)			`[inline]`

Full Constructor, setting the action descriptor to a, the new table rows to _n, and the annotations that have to be removed to _r.

Definition at line 64 of file table_delta.h.

coco::table_delta::table_delta ( const table_delta & __d ) [inline]

Standard Copy Constructor

Definition at line 69 of file table_delta.h.

coco::table_delta::table_delta	(	const std::string &	a,
		const std::string &	__tn,
		const dbt_row &	__t
	)			`[inline]`

Constructor, setting the action descriptor to a, and adding one row __t to the table __tn.

Definition at line 79 of file table_delta.h.

coco::table_delta::table_delta	(	const std::string &	a,
		const std::string &	__tn,
		const std::vector< dbt_row > &	__t
	)			`[inline]`

Constructor, setting the action descriptor to a, and adding a list of rows __t to the table __tn.

Definition at line 85 of file table_delta.h.

Member Function Documentation

void coco::table_delta::add ( const std::vector< t_line > & _tlv ) [inline]

This method adds a list of table rows.

Definition at line 100 of file table_delta.h.

void coco::table_delta::add	(	const std::string &	_tn,
		const dbt_row &	_r
	)			`[inline]`

This method adds one row _r to the table _tn.

Definition at line 97 of file table_delta.h.

void coco::table_delta::add ( const t_line & _tl ) [inline]

This method adds one table row.

Definition at line 95 of file table_delta.h.

bool coco::table_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. This will never be used, because the point_delta is converted to annotation_delta before the apply is performed.

Reimplemented from coco::delta_base.

Reimplemented in coco::boxes_delta, and coco::point_delta.

Definition at line 35 of file table_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.

void coco::table_delta::convert	(	work_node &	_x,
		delta_base *&	_u
	)			`[virtual]`

This method converts the table delta to an annotation_delta after the information is stored in the search database. The conversion is based on work_node _x, and the generated annotation_delta is returned via _u.

Reimplemented from coco::delta_base.

Definition at line 42 of file table_delta.cc.

virtual void coco::table_delta::create_table	(	work_node &	_x,
		vdbl::standard_table *&	ptb,
		const std::string &	__t
	)			const `[inline, virtual]`

This method creates the table with name __t in the search database for the work_node _x. A pointer ptb to the created table is set. This method must be overloaded by the subclasses.

Reimplemented in coco::boxes_delta, and coco::point_delta.

Definition at line 119 of file table_delta.h.

virtual void coco::table_delta::destroy_copy ( delta_base * __d ) const [inline, virtual]

Clone Destructor

Reimplemented in coco::boxes_delta, and coco::point_delta.

Definition at line 114 of file table_delta.h.

const std::string& coco::delta_base::get_action ( ) const [inline, inherited]

Retrieve the action information (the delta type) for this delta.

Definition at line 184 of file api_deltabase.h.

delta coco::delta_base::make_delta ( const std::string & a ) [inline, inherited]

Construct a delta from this delta_base with the action a.

Definition at line 175 of file api_deltabase.h.

virtual table_delta* coco::table_delta::new_copy ( ) const [inline, virtual]

Clone Operation

Reimplemented from coco::delta_base.

Reimplemented in coco::boxes_delta, and coco::point_delta.

Definition at line 134 of file table_delta.h.

void coco::table_delta::rm ( const std::vector< annotation > & _trv ) [inline]

This method adds the annotations in _trv to the list of removed annotations.

Definition at line 107 of file table_delta.h.

void coco::table_delta::rm ( const annotation & _tr ) [inline]

This method adds the annotation _tr to the list of removed annotations.

Definition at line 104 of file table_delta.h.

virtual void coco::delta_base::unkeep ( ) [inline, virtual, inherited]

Perform this operation when the delta is released (unkept) from a work_node.

Reimplemented in coco::dag_delta.
