CGAL 4.14 - Combinatorial Maps
CellAttribute Concept Reference

Definition

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

Has Models:
CGAL::Cell_attribute<Map,Info_,Tag,OnMerge,OnSplit>
GenericMap
GenericMapItems

Types

typedef unspecified_type Dart_handle
Dart handle type.

typedef unspecified_type Dart_const_handle
Dart const handle type.

typedef unspecified_type Info
Type of the information contained in the attribute. More...

typedef unspecified_type Supports_cell_dart
Equals to Tag_true to enable the storage of a Dart_handle of the associated cell, Tag_false otherwise.

typedef unspecified_type On_merge
Functor called before merging two attributes. More...

typedef unspecified_type On_split
Functor called after an attribute was split in two. More...

Creation

CellAttribute ()

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

Access Member Functions

Dart_handle dart ()
Returns one dart of the cell associated to this attribute. More...

Dart_const_handle dart () const
Returns one dart of the cell associated to this attribute, when it is const. More...

void set_dart (Dart_handle ahandle)
Sets the dart of the cell associated to this attribute to ahandle, if Supports_cell_dart is equal to Tag_true. More...

Infoinfo ()
Returns the information of this attribute. More...

const Infoinfo () const
Returns the information of this attribute, when it is const. More...

◆ 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

Functor called before merging two attributes.

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

◆ 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.

◆ dart() [1/2]

 Dart_handle CellAttribute::dart ( )

Returns one dart of the cell associated to this attribute.

NULL if Supports_cell_dart is equal to Tag_false.

◆ dart() [2/2]

 Dart_const_handle CellAttribute::dart ( ) const

Returns one dart of the cell associated to this attribute, when it is const.

NULL if Supports_cell_dart is equal to Tag_false.

◆ 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_handle ahandle )

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

Otherwise, this method does nothing.

Precondition
ahandle belongs to the cell associated to this attribute.
