SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
Interface implemented by double precision floating point variables. The domain associated with this type of variable can be modified unlike CspDoubleExpr objects.
Method Summary | |
double |
getMax()
Returns the maximum value of this variable's domain |
double |
getMin()
Returns the minimum value of this variable's domain |
double |
getNextHigher(double val)
Returns the next higher value in this variable's domain or current value if none exists |
double |
getNextLower(double val)
Returns the next lower value in this variable's domain or current value if none exists |
boolean |
isInDomain(double val)
Returns true if the specified value is in this variable's domain |
void |
removeAll(DoubleSet set)
Attempts to reduce this variable's domain by removing a set of values |
void |
removeRange(double start,
double end)
Attempts to reduce this variable's domain by removing a range of values |
void |
removeValue(double val)
Attempts to remove a single value from this variable's domain |
void |
setMax(double val)
Attempts to reduce this variable's domain to be less than the specified maximum value. |
void |
setMin(double val)
Attempts to reduce this variable's domain to be greater than the specified minimum value. |
void |
setRange(double start,
double end)
Attempts to reduce this variable's domain to within a range of values |
void |
setValue(double val)
Attempts to reduce this variable's domain to a single value. |
