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

 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.

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

Member Typedef Documentation

◆ 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.

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.
