Constructor Detail

HyperSetUnionArc

public HyperSetUnionArc(SetNode[] sources,
                        SetNode target)

Constructor

Parameters:

sources - Source nodes in equation

target - Target node in equation

Method Detail

toString

public java.lang.String toString()

Returns string representation of arc

propagate

public final void propagate()
                     throws jopt.csp.variable.PropagationFailureException

Description copied from interface: Arc

Attempts to reduce values in target node domain based on values in all source nodes

Throws:

jopt.csp.variable.PropagationFailureException - If domain of target node becomes empty

propagate

public final void propagate(Node src)
                     throws jopt.csp.variable.PropagationFailureException

Description copied from interface: Arc

Attempts to reduce values in target node domain based on values in given source node

Parameters:

src - Source node that caused propagation to occur

Throws:

jopt.csp.variable.PropagationFailureException - If domain of target node becomes empty
