CellAttribute Concept Reference

Definition

The concept CellAttribute represents a non void attribute associated with a cell of a generic map. It can keep a descriptor to one dart of its associated cell, and can contain any information.

Has models

Types
typedef unspecified_type	Dart_descriptor
	Dart descriptor type.
typedef unspecified_type	Dart_const_descriptor
	Dart const descriptor type.
typedef unspecified_type	Info
	Type of the information contained in the attribute.
typedef unspecified_type	Supports_cell_dart
	Equals to Tag_true to enable the storage of a Dart_descriptor of the associated cell, Tag_false otherwise.
typedef unspecified_type	On_merge
	Functor called before merging two attributes.
typedef unspecified_type	On_split
	Functor called after an attribute was split in two.

Creation
	CellAttribute ()
	Cell_attribute (const Info &info)
	Constructor initializing the information of this attribute by the copy constructor Info(info).

Access Member Functions
Dart_descriptor	dart ()
	Returns one dart of the cell associated to this attribute, if Supports_cell_dart is equal to Tag_true.
Dart_const_descriptor	dart () const
	Returns one dart of the cell associated to this attribute, when it is const, if Supports_cell_dart is equal to Tag_true.
void	set_dart (Dart_descriptor d)
	Sets the dart of the cell associated to this attribute to ah, if Supports_cell_dart is equal to Tag_true.
Info &	info ()
	Returns the information of this attribute.
const Info &	info () const
	Returns the information of this attribute, when it is const.

Member Typedef Documentation

Info

typedef unspecified_type CellAttribute::Info

Type of the information contained in the attribute.

If void, the cell attribute does not have any information.

On_merge

typedef unspecified_type CellAttribute::On_merge

Functor called before merging two attributes.

It must be a binary functor taking as argument two references to a model of CellAttribute.

On_split

typedef unspecified_type CellAttribute::On_split

Functor called after an attribute was split in two.

It must be a binary functor taking as argument two references to a model of CellAttribute.

Member Function Documentation

Cell_attribute()

CellAttribute::Cell_attribute

(

const Info &

info

)

Constructor initializing the information of this attribute by the copy constructor Info(info).

Defined only if Info is different from void.

info() [1/2]

Info & CellAttribute::info

(

)

Returns the information of this attribute.

Defined only if Info is different from void.

info() [2/2]

const Info & CellAttribute::info

(

)

const

Returns the information of this attribute, when it is const.

Defined only if Info is different from void.

set_dart()

void CellAttribute::set_dart

(

Dart_descriptor

d

)

Sets the dart of the cell associated to this attribute to ah, if Supports_cell_dart is equal to Tag_true.

Otherwise, this method does nothing.

Precondition

d belongs to the cell associated to this attribute.
