Member Typedef Documentation

typedef unspecified_type CellAttribute::Info

Type of the information contained in the attribute.

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

typedef unspecified_type CellAttribute::On_merge

Functor called before merging two attributes.

Must be a model of the Binary Function concept having two references to a model of CellAttribute as type of both arguments and void as return type.

typedef unspecified_type CellAttribute::On_split

Functor called after an attribute was split in two.

Must be a model of the Binary Function concept having two references to a model of CellAttribute as type of both arguments and void as return type.

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_handle CellAttribute::dart

(

)

Returns one dart of the cell associated to this attribute.

NULL if Supports_cell_dart is equal to Tag_false.

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& CellAttribute::info

(

)

Returns the information of this attribute.

Defined only if Info is different from void.

const Info& CellAttribute::info

(

)

const

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

Defined only if Info is different from void.

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.
