Constructor & Destructor Documentation

Gecode::IntSet::IntSet ( void   )  [inline]

Initialize as empty set.

Definition at line 47 of file int-set-1.hpp.

Gecode::IntSet::IntSet ( int  n,
int  m 
) [inline]

Initialize as range with minimum n and maximum m.

Note that the set is empty if n is larger than m

Definition at line 93 of file int-set-1.hpp.

Gecode::IntSet::IntSet ( const int  r[],
int  n 
) [inline]

Initialize with n integers from array r.

Definition at line 88 of file int-set-1.hpp.

Gecode::IntSet::IntSet ( const int  r[][2],
int  n 
) [inline]

Initialize with n ranges from array r.

For position i in the array r, the minimum is r[i][0] and the maximum is r[i][1].

Definition at line 83 of file int-set-1.hpp.
