                        BinRelation rela)

Method Detail

clone

public java.lang.Object clone()

Description copied from interface: Constraint

returns a copy of the constraint. This copy is a new object, may be a recursive copy in case of composite constraints. The original and the copy share the same variables & plugins

Specified by:

clone in interface Constraint

Overrides:

clone in class AbstractConstraint

Returns:

reviseV1

public void reviseV1()
              throws ContradictionException

Throws:

ContradictionException

reviseV0

public void reviseV0()
              throws ContradictionException

Throws:

ContradictionException

propagate

public void propagate()
               throws ContradictionException

Description copied from class: AbstractBinIntConstraint

Propagates on the constraint awake events.

Specified by:

propagate in interface Propagator

Overrides:

propagate in class AbstractBinIntConstraint

Throws:

ContradictionException

awakeOnRem

public void awakeOnRem(int idx,
                       int x)
                throws ContradictionException

Description copied from class: AbstractIntConstraint

Default propagation on one value removal: propagation on domain revision.

Specified by:

awakeOnRem in interface IntVarEventListener

Overrides:

awakeOnRem in class AbstractIntConstraint

Throws:

ContradictionException

awakeOnInf

public void awakeOnInf(int idx)
                throws ContradictionException

Propagation when a minimal bound of a variable was modified.

Specified by:

awakeOnInf in interface IntVarEventListener

Overrides:

awakeOnInf in class AbstractIntConstraint

Parameters:

idx - The index of the variable.

Throws:

ContradictionException

awakeOnSup

public void awakeOnSup(int idx)
                throws ContradictionException

Description copied from class: AbstractIntConstraint

Default propagation on improved upper bound: propagation on domain revision.

Specified by:

awakeOnSup in interface IntVarEventListener

Overrides:

awakeOnSup in class AbstractIntConstraint

Throws:

ContradictionException

awakeOnInst

public void awakeOnInst(int idx)
                 throws ContradictionException

Propagation when a variable is instantiated.

Specified by:

awakeOnInst in interface IntVarEventListener

Overrides:

awakeOnInst in class AbstractIntConstraint

Parameters:

idx - The index of the variable.

Throws:

ContradictionException

opposite

public AbstractConstraint opposite()

Description copied from interface: Constraint

computes the constraint modelling the counter-opposite condition of this

Specified by:

opposite in interface Constraint

Overrides:

opposite in class AbstractConstraint

Returns:

a new constraint (modelling the opposite condition)
