Gecode::Int::IntVarImp::RangeList Class Reference

Lists of ranges (intervals). More...

#include <var-imp.hpp>

List of all members.

Protected Attributes

int _min
 Minimum of range.
int _max
 Maximum of range.

Constructors



 RangeList (void)
 Default constructor (noop).
 RangeList (int min, int max)
 Initialize with minimum min and maximum max.
 RangeList (int min, int max, RangeList *p, RangeList *n)
 Initialize with minimum min and maximum max and predecessor p and successor n.

Access



int min (void) const
 Return minimum.

void prev (RangeList *o, RangeList *n)
 Set previous element from o to n.
void fix (RangeList *n)
 Restore simple link to next element (so that it becomes a true free list).

Memory management

 Free memory for this element.
static void * operator new (size_t s, Space &home)
 Allocate memory from space.
static void * operator new (size_t s, void *p)
 Placement new.
static void operator delete (void *)
 No-op (for exceptions).
static void operator delete (void *, Space &)
 No-op (use dispose instead).
static void operator delete (void *, void *)
 No-op (use dispose instead).

Detailed Description

Lists of ranges (intervals).

Range lists are doubly-linked storing the pointer to both the next and the previous element in a single pointer. That means that the next element is only available when the previous element is supplied as additional information. The same holds true for access to the previous element.
