Detailed Description

template<int n, typename Symmetry>
class operations_research::math_opt::AttrDiff< n, Symmetry >

Tracks modifications to an Attribute with a key size of n (e.g., variable lower bound has a key size of 1).

Member Typedef Documentation

Key

template<int n, typename Symmetry>

using operations_research::math_opt::AttrDiff< n, Symmetry >::Key = AttrKey<n, Symmetry>

Constructor & Destructor Documentation

AttrDiff()

template<int n, typename Symmetry>

operations_research::math_opt::AttrDiff< n, Symmetry >::AttrDiff ( )

default

On creation, the attribute is not modified for any key.

Member Function Documentation

Advance()

template<int n, typename Symmetry>

void operations_research::math_opt::AttrDiff< n, Symmetry >::Advance ( )

inline

Clear all tracked modifications.

Definition at line 36 of file attr_diff.h.

Erase()

template<int n, typename Symmetry>

void operations_research::math_opt::AttrDiff< n, Symmetry >::Erase ( const Key key )

inline

Stop tracking modifications for this attribute key. (Typically invoked when an element in the key was deleted from the model.)

Definition at line 50 of file attr_diff.h.

has_modified_keys()

template<int n, typename Symmetry>

bool operations_research::math_opt::AttrDiff< n, Symmetry >::has_modified_keys ( ) const

inline

Definition at line 46 of file attr_diff.h.

modified_keys()

template<int n, typename Symmetry>

const AttrKeyHashSet< Key > & operations_research::math_opt::AttrDiff< n, Symmetry >::modified_keys ( ) const

inline

Returns the attribute keys that have been modified for this attribute (the elements where set_modified() was called without a subsequent call to Advance()).

Definition at line 44 of file attr_diff.h.

SetModified()

template<int n, typename Symmetry>

void operations_research::math_opt::AttrDiff< n, Symmetry >::SetModified ( const Key key )

inline

Mark the attribute as modified for key.
