Class groupRelation

java.lang.Object
  cayleytable.groupRelation

public class groupRelation
extends java.lang.Object

Class used to store the relationships between generators of groups being created in the groupCreator.createDefineRelationGroup method.

Author:

Field Summary

(package private) java.lang.String	left String Object that stores the LHS of the relationship equation
(package private) java.lang.String	right String Object that stores the RHS of the relationship equation

Constructor Summary

groupRelation(int generator, int genSize)
Creates a new instance of groupRelation containing a generator raised to some power being equal to the identity element or an empty RHS.

groupRelation(int gen1, int gen2, java.lang.String rgt, java.util.ArrayList generatorList)
Creates a new instance of groupRelation containing a "pseudo" commutative defined relationship of the group.

groupRelation(java.lang.String relationship, java.util.ArrayList generatorList)
Creates a new instance of groupRelation containing a relationship defined completely by the user through the user interface.

Method Summary

java.lang.String	getLeft() Returns LHS of the groupRelation.
java.lang.String	getRight() Returns RHS of the groupRelation.

Constructor Detail

groupRelation

public groupRelation(int generator,
                     int genSize)

Creates a new instance of groupRelation containing a generator raised to some power being equal to the identity element or an empty RHS.

Parameters:

generator - Generator for which the groupRelation is being created

genSize - Order of generator for which relation is being generated.

groupRelation

public groupRelation(java.lang.String relationship,
                     java.util.ArrayList generatorList)

Creates a new instance of groupRelation containing a relationship defined completely by the user through the user interface.

Parameters:

relationship - String object that represents the relationship being created.

generatorList - ArrayList of String objects that are the order of each of the generators of the group for use in determining the inverse of a generator.

groupRelation

public groupRelation(int gen1,
                     int gen2,
                     java.lang.String rgt,
                     java.util.ArrayList generatorList)

Creates a new instance of groupRelation containing a "pseudo" commutative defined relationship of the group.

Parameters:

gen1 - Integer representing the first generator in the "pseudo" commutative defined relationship

gen2 - Integer representing the second generator in the "pseudo" commutative defined relationship

rgt - String object containing the RHS of the "pseudo" commutative defined relationship

generatorList - ArrayList of String objects that are the order of each of the generators of the group for use in determining the inverse of a generator.

Method Detail

getLeft

public java.lang.String getLeft()

Returns LHS of the groupRelation.

Returns:

String object containing LHS of relation equation.

getRight

public java.lang.String getRight()

Returns RHS of the groupRelation.

Returns:

String object containing RHS of relation equation.
