Class SegmentInfo

java.lang.Object
  y.layout.router.polyline.AbstractSegmentInfo
      y.layout.router.polyline.SegmentInfo

public class SegmentInfo
extends AbstractSegmentInfo

A SegmentInfo holds information about the possible location of an orthogonal edge segment. Most notably, it stores the direction of the segment and the interval that restricts the location of the segment.

Constructor Detail

SegmentInfo

public SegmentInfo(Edge edge,
                   int segmentIndex,
                   Direction direction,
                   Interval locationRange,
                   Interval minExtension,
                   Interval maxExtension,
                   java.util.List cellSegmentInfos)

Creates a new instance of SegmentInfo with the given information.

Parameters:

edge - the edge to which the segment of this info belongs

segmentIndex - the index of the segment to which this info belongs

direction - the direction to which the segment of this info points

locationRange - the range within which the common location of this segment has to lie

minExtension - the minimum interval in extension direction this segment is known to intersect

maxExtension - the maximum interval in extension direction this segment will span

cellSegmentInfos - the list of CellSegmentInfo objects upon which this segment info is built

SegmentInfo

public SegmentInfo(Edge edge,
                   int segmentIndex,
                   LineSegment segment)

Creates a new instance of SegmentInfo using a LineSegment to describe the edge segment.

This constructor is meant to be used for fixed orthogonal edge segments already knowing their extension and location.

Parameters:

edge - the edge to which the segment of this info belongs

segmentIndex - the index of the segment to which this info belongs

segment - a line segment describing the edge segment

Method Detail

getEdge

public Edge getEdge()

Returns the edge to which the segment of this info belongs.

Returns:

the edge to which the segment of this info belongs

cellSegmentInfoCount

public int cellSegmentInfoCount()

Returns the number of CellSegmentInfo of this segment info.

Returns:

the number of CellSegmentInfo of this segment info

getCellSegmentInfo

public CellSegmentInfo getCellSegmentInfo(int index)

Returns the CellSegmentInfo at the given index of this segment info.

Parameters:

index - the index of the CellSegmentInfo to return

Returns:

the CellSegmentInfo at the given index of this segment info

setSegmentGroup

public void setSegmentGroup(SegmentGroup segmentGroup)

Specifies the segment group for this segment info and its associated CellSegmentInfos. The location ranges are adjusted to use the SegmentGroup.getCommonLocationRange().

Overrides:

setSegmentGroup in class AbstractSegmentInfo

Parameters:

segmentGroup - the segment group to which this segment info shall belong

setAtStrongPortConstraint

public void setAtStrongPortConstraint(boolean atStrongPortConstraint)

Specifies whether or not this edge segment has the restriction of a strong PortConstraint.

Parameters:

atStrongPortConstraint - true if this edge segment has the restriction of a strong PortConstraint, false otherwise
