Detailed Description

Recording actions for integer variables.

Definition at line 4377 of file int.hh.

Constructor & Destructor Documentation

◆ IntAction() [1/3]

Gecode::IntAction::IntAction ( void )
inline

Construct as not yet initialized.

The only member functions that can be used on a constructed but not yet initialized action storage is init or the assignment operator.

Definition at line 37 of file action.hpp.

◆ IntAction() [2/3]

Gecode::IntAction::IntAction ( const IntAction & a)
inline

Copy constructor.

Definition at line 40 of file action.hpp.

◆ IntAction() [3/3]

Gecode::IntAction::IntAction ( Home home,
const IntVarArgs & x,
double d = 1.0,
IntBranchMerit bm = nullptr )

Initialize for integer variables x with decay factor d.

If the branch merit function bm is different from nullptr, the action for each variable is initialized with the merit returned by bm.

Definition at line 38 of file action.cpp.

Member Function Documentation

◆ operator=()

IntAction & Gecode::IntAction::operator= ( const IntAction & a)
inline

Assignment operator.

Definition at line 44 of file action.hpp.

◆ init()

void Gecode::IntAction::init ( Home home,
const IntVarArgs & x,
double d = 1.0,
IntBranchMerit bm = nullptr )

Initialize for integer variables x with decay factor d.

If the branch merit function bm is different from nullptr, the action for each variable is initialized with the merit returned by bm.

This member function can only be used once and only if the action storage has been constructed with the default constructor.
