BoolNotView(BoolVar var)
Create a not view based on var
|
Modifier and Type | Method and Description |
---|---|
void |
_setNot(BoolVar not) |
boolean |
contains(int value)
Checks if a value
v belongs to the domain of this |
ESat |
getBooleanValue() |
int |
getLB()
Retrieves the lower bound of the variable
|
int |
getTypeAndKind()
Return a MASK composed of 2 main information: TYPE and KIND.
|
int |
getUB()
Retrieves the upper bound of the variable
|
int |
getValue()
Retrieves the current value of the variable if instantiated, otherwier the lower bound.
|
boolean |
hasNot() |
boolean |
instantiateTo(int value,
ICause cause)
Instantiates the domain of
this to value . |
boolean |
isInstantiatedTo(int value)
Checks wether
this is instantiated to val |
boolean |
isLit()
Current tree is a literal
|
boolean |
isNot()
Current tree is rooted with NOT logical operator
This is a one way relationship: in case a = not(b)
a.isNot() returns true whereas b.isNot() returns false (unless b = not(c)...)
|
void |
justifyEvent(IntVar var,
ICause cause,
IntEventType mask,
int one,
int two,
int three)
This methods is related to explanations, it binds an event occurring on the observed
variable to the view.
|
IIntDeltaMonitor |
monitorDelta(ICause propagator)
Allow to monitor removed values of
this . |
int |
nextValue(int v)
Returns the first value just after v in
this which is in the domain. |
int |
nextValueOut(int v)
Returns the first value just after v in
this which is out of the domain. |
BoolVar |
not() |
int |
previousValue(int v)
Returns the previous value just before v in
this . |
int |
previousValueOut(int v)
Returns the first value just before v in
this which is out of the domain. |
boolean |
removeAllValuesBut(IntIterableSet values,
ICause cause)
Removes all values from the domain of
this except those in values . |
boolean |
removeInterval(int from,
int to,
ICause cause)
Removes values between [
from, to ] from the domain of this . |
boolean |
removeValue(int value,
ICause cause)
Removes
value from the domain of this . |
boolean |
removeValues(IntIterableSet values,
ICause cause)
Removes the value in
values from the domain of this . |
void |
setNot(boolean isNot)
States whether or not this variable is the negation of another.
|
boolean |
setToFalse(ICause cause) |
boolean |
setToTrue(ICause cause) |
String |
toString() |
int |
transformValue(int value) |
boolean |
updateBounds(int lb,
int ub,
ICause cause)
Updates the lower bound and the upper bound of the domain of
this to, resp. |
boolean |
updateLowerBound(int value,
ICause cause)
Updates the lower bound of the domain of
this to value . |
boolean |
updateUpperBound(int value,
ICause cause)
Updates the upper bound of the domain of
this to value . |
boolean |
why(RuleStore ruleStore,
IntVar modifiedVar,
IEventType evt,
int value)
Add new rules to the rule store
