Direct Known Subclasses:

TestFactorSet

public class FactorSet

extends java.lang.Object

An object of this class represents a set of unique factors, of the form "x to the power of y". The factors contained within a factor set object are kept automatically in order at all times. A new factor may be added to the factor set by calling the "multiply" method, and passing the new factor as an argument. A factor set object of this type, may be used to conveniently accumulate factors produced by any given process.

Constructor Summary

FactorSet() Construct an empty factor set object.

Method Summary

int	length() Determine the number of unique factors contained, within a factor set object.
static void	main(java.lang.String[] args)
protected void	multiply(java.math.BigInteger n) Add a new factor to a factor set object.
protected lima.mathematical.factorisation.Factor[]	toArray() Convert a factor set object into an array of factor objects.
java.lang.String	toString() Generate a textual description of a factor set object.

FactorSet

protected FactorSet()

Construct an empty factor set object.

Method Detail

toString

public java.lang.String toString()

Generate a textual description of a factor set object.

Overrides:

toString in class java.lang.Object

toArray

protected lima.mathematical.factorisation.Factor[] toArray()

Convert a factor set object into an array of factor objects.

length

public int length()

Determine the number of unique factors contained, within a factor set object.

multiply

protected void multiply(java.math.BigInteger n)

Add a new factor to a factor set object. The operation is equivalent to the operation of multiplying the factor set object with the new factor.
