## devisor2.foundation.boundary
Class BoundaryNode

    java.lang.Object
      devisor2.foundation.GridItem
          devisor2.foundation.elements.Node
              devisor2.foundation.boundary.BoundaryNode

All Implemented Interfaces:
  java.io.Serializable

public class BoundaryNode
extends Node
implements java.io.Serializable

This class BoundaryNode represents a BoundaryNode of a grid, which is more special than a regular node, because its position is not controlled via the coordinates, but via a parameter value on the boundary segment.

See Also:
  Serialized Form

Field Summary
`Boundary` | `boundary` the boundary the node lies on
`Segment` | `segment` the segment the node lies on
`double` | `t` parameter value of the node on the specific boundary (range: 0 to segmentcount of the specific boundary)

Fields inherited from class devisor2.foundation.elements.Node
`coord, index, marker, npr, number, parents, value`

Fields inherited from class devisor2.foundation.GridItem
`cc, marked, transformed, xmax, xmin, ymax, ymin`

Constructor Summary
`BoundaryNode()` Creates a boundary node with parameter value 0
`BoundaryNode(double tt, Boundary bn)` Creates a boundary node with parameter value tt on boundary bn of the DomainBoundary
`BoundaryNode(double tt, Boundary bn, Segment s)` Creates a boundary node with parameter value tt on boundary bn of the DomainBoundary

Method Summary
`java.lang.Object` | `clone()` returns a copy of this boundary node
`Boundary` | `getBoundary()` returns the boundary of this node
`int` | `getBoundaryNumber()` returns the number of the defining boundary
`double` | `getParaValue()` returns the parameter value of this node
`Segment` | `getSegment()` returns the segment the node lies on
`void` | `setBoundary(Boundary bn)` sets the boundary of this node
`void` | `setParaValue(double tt)` sets the parameter value of this boundary node and updates coordinates accordingly
`void` | `setSegment(Segment s)` sets the segment to the new value
`void` | `swap()` swaps the parameter value of this node
`java.lang.String` | `toString()` prints the node's coordinates to the standard output
`void` | `updateBoundaryNode()` sets the cartesian coordinates of the node according to the parameter value
