bool Gecode::Float::FloatVarImp::in ( const FloatVal &  n  )  const [inline]

Test whether n is contained in domain.

Definition at line 108 of file float.hpp.

ModEvent Gecode::Float::FloatVarImp::eq ( Space &  home,
FloatNum  n 
) [inline]

Restrict domain values to be equal to n.

Definition at line 185 of file float.hpp.

ModEvent Gecode::Float::FloatVarImp::eq ( Space &  home,
const FloatVal &  n 
) [inline]

Restrict domain values to be equal to n.

Definition at line 195 of file float.hpp.

ModEvent Gecode::Float::FloatVarImp::lq ( Space &  home,
FloatNum  n 
) [inline]

Restrict domain values to be less or equal than n.

Definition at line 159 of file float.hpp.

ModEvent Gecode::Float::FloatVarImp::lq ( Space &  home,
const FloatVal &  n 
) [inline]

Restrict domain values to be less or equal than n.

Definition at line 171 of file float.hpp.

void Gecode::Float::FloatVarImp::subscribe ( Space &  home,
Propagator &  p,
PropCond  pc,
bool  schedule = true 
)

Subscribe propagator p with propagation condition pc to variable.

In case schedule is false, the propagator is just subscribed but not scheduled for execution (this must be used when creating subscriptions during propagation).

Definition at line 50 of file float.cpp.

Subscribe advisor a to variable.

The advisor a is only subscribed if assigned is false.

If fail is true, the advisor a is also run when a variable operation triggers failure. This feature is undocumented.

Definition at line 61 of file float.cpp.
