public class Part
extends Edge
Generic "part" class.

For a conceptual overview, refer to the description of the base class, Edge, in the kernel package, and to the class PartFactory in this package.

Version:

Author:

Variable Index

o dimensions
The number of dimensions of this part.
o params
A generic part may contain arbitrary parameters, none of which has any meaning to the part itself.
o trans
The "shape" of the generic part is given by a transformation.

Constructor Index

o Part()
o Part(ParamSet, int)

Method Index

o clone()
This is supposed to make a deep copy of the Edge.
o cloneInto(Part)
o equals(Object)
o findTrans(PointSequence, TransFinder, boolean)
This implementation always returns null, indicating that a generic part cannot be used as an hyperedge per se.
o getDimensions()
o getParams()
o initTransformation()
o transform(Transformation)
Transforms the edge with the given transformation.

Variables

o dimensions 
  protected int dimensions
The number of dimensions of this part.

Currently only 2- and 3-dimensional parts are supported by this class.

o trans 
  protected MatrixTrans trans
The "shape" of the generic part is given by a transformation.

o params 
  protected ParamSet params
A generic part may contain arbitrary parameters, none of which has any meaning to the part itself. If a generic part is used directly, the parameters may be used to apply specific higher level semantics to the part.

Constructors

o Part 
  public Part(ParamSet params,
              int dimensions)
o Part 
  protected Part()

Methods

o initTransformation 
  protected void initTransformation()
o getDimensions 
  public int getDimensions()
o getParams 
  public ParamSet getParams()
o transform 
  public void transform(Transformation t)
Transforms the edge with the given transformation.

Overrides:
transform in class Edge
o findTrans 
  public Transformation findTrans(PointSequence s,
                                  TransFinder finder,
                                  boolean inverse)
This implementation always returns null, indicating that a generic part cannot be used as an hyperedge per se.

Of course, derived classes can implement replacement behaviour.

Overrides:
findTrans in class Edge
o equals 
  public boolean equals(Object obj)
Overrides:
equals in class Object
o cloneInto 
  protected void cloneInto(Part into)
o clone 
  public Object clone()
This is supposed to make a deep copy of the Edge.

Overrides:
clone in class Edge
