Constructor Detail

ConstraintEdge

public ConstraintEdge(DetectorNode source,
                      DetectorNode target)

Constructor.

Parameters:

source - the source vertex (earlier Detector)

target - the target vertex (later Detector)

Method Detail

setConstraint

public void setConstraint(DetectorOrderingConstraint constraint)

Set the DetectorOrderingConstraint that created this edge.

Parameters:

constraint - the DetectorOrderingConstraint that created this edge

isSingleSource

public boolean isSingleSource()

Determine whether or not this ConstraintEdge resulted from an ordering constraint having a single detector as its source (ealier detector). Such constraints automatically enable the source (earlier) detector if the target (later) detector is enabled.

Returns:

true if this edge has a single detector as its source (earlier detector)
