Constructor Detail

Primitive

public Primitive(int type,
                 java.lang.String name)

Constructs the primitive of the type and name

Primitive

public Primitive(java.lang.String type,
                 java.lang.String name)

Constructs the primitive of the type and name

Method Detail

convertFrom

public static Primitive convertFrom(GeometricObject o,
                                    int index)

Constructs a primitive from a given object with index in the name. Example: if index is 4 and the object is a line the primitive will be "line l4".

toString

public java.lang.String toString()

String description of the primitive (like "line l2") - includes both type and name

Overrides:

toString in class java.lang.Object

equals

public boolean equals(java.lang.Object p)

The two primitives are the same if their name and type are the same. For use in hashtable representing the constraint graph.

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

The hashcode of a primitive is a hash code of it's string description. For use in hashtable representing the constraint graph

Overrides:

hashCode in class java.lang.Object

name

public java.lang.String name()

Name of the primitive (like "l2" in "line l2")

type

public int type()

Type of the primitive (like "line" in "line l2")

clone

public java.lang.Object clone()

Clone the primitive

Overrides:

clone in class java.lang.Object
