Class RelativeBendpoint

java.lang.Object
org.eclipse.draw2d.RelativeBendpoint
All Implemented Interfaces:
Bendpoint

public class RelativeBendpoint extends Object implements Bendpoint
RelativeBendpoint is a Bendpoint that calculates its location based on its distance from the start and end points of the Connection, as well as its weight. See setWeight(float) for a description of what behavior different weights will provide.
  • Constructor Details

    • RelativeBendpoint

      public RelativeBendpoint()
      Constructs a new RelativeBendpoint.
      Since:
      2.0
    • RelativeBendpoint

      public RelativeBendpoint(Connection conn)
      Constructs a new RelativeBendpoint and associates it with the given Connection.
      Parameters:
      conn - The Connection this Bendpoint is associated with
      Since:
      2.0
  • Method Details

    • getConnection

      protected Connection getConnection()
      Returns the Connection this Bendpoint is associated with.
      Returns:
      The Connection this Bendpoint is associated with
      Since:
      2.0
    • getLocation

      public Point getLocation()
      Calculates and returns this Bendpoint's new location.
      Specified by:
      getLocation in interface Bendpoint
      Returns:
      This Bendpoint's new location
      Since:
      2.0
    • setConnection

      public void setConnection(Connection conn)
      Sets the Connection this bendpoint should be associated with.
      Parameters:
      conn - The Connection this bendpoint should be associated with
      Since:
      2.0
    • setRelativeDimensions

      public void setRelativeDimensions(Dimension dim1, Dimension dim2)
      Sets the Dimensions representing the X and Y distances this Bendpoint is from the start and end points of the Connection. These Dimensions are generally set once and are used in calculating the Bendpoint's location.
      Parameters:
      dim1 - The X and Y distances this Bendpoint is from the start of the Connection
      dim2 - The X and Y distances this Bendpoint is from the end of the Connection
      Since:
      2.0
    • setWeight

      public void setWeight(float w)
      Sets the weight this Bendpoint should use to calculate its location. The weight should be between 0.0 and 1.0. A weight of 0.0 will cause the Bendpoint to follow the start point, while a weight of 1.0 will cause the Bendpoint to follow the end point. A weight of 0.5 (the default) will cause the Bendpoint to maintain its original aspect ratio between the start and end points.
      Parameters:
      w - The weight
      Since:
      2.0
