Class BigIntegerGene

java.lang.Object

io.jenetics.ext.BigIntegerGene

All Implemented Interfaces:

BoundedGene<BigInteger, BigIntegerGene>, Gene<BigInteger, BigIntegerGene>, NumericGene<BigInteger, BigIntegerGene>, Factory<BigIntegerGene>, Mean<BigIntegerGene>, Self<BigIntegerGene>, Verifiable, Serializable, Comparable<BigIntegerGene>

public final class BigIntegerGene
extends Object
implements NumericGene<BigInteger, BigIntegerGene>, Mean<BigIntegerGene>, Serializable

Numeric chromosome implementation which holds an arbitrary sized integer number.

This is a value-based class; use of identity-sensitive operations (including reference equality (==), identity hash code, or synchronization) on instances of IntegerGene may have unpredictable results and should be avoided.

3.5

Method Details

allele

public BigInteger allele()

Description copied from interface: Gene

Return the allele of this gene.

Specified by:

allele in interface Gene<BigInteger, BigIntegerGene>

Returns:

the allele of this gene.

min

public BigInteger min()

Description copied from interface: BoundedGene

Return the allowed min value.

Specified by:

min in interface BoundedGene<BigInteger, BigIntegerGene>

Returns:

The allowed min value.

max

public BigInteger max()

Description copied from interface: BoundedGene

Return the allowed max value.

Specified by:

max in interface BoundedGene<BigInteger, BigIntegerGene>

Returns:

The allowed max value.

mean

public BigIntegerGene mean(BigIntegerGene that)

Description copied from interface: Mean

Return the (usually arithmetic) mean value of this and that. For NumericGenes the mean is the arithmetic mean.

Specified by:

mean in interface Mean<BigIntegerGene>

Parameters:

that - the second value for calculating the mean.

Returns:

the mean value of this and that.

newInstance

public BigIntegerGene newInstance(Number number)

Specified by:

newInstance in interface NumericGene<BigInteger, BigIntegerGene>

newInstance

public BigIntegerGene newInstance(BigInteger value)

Description copied from interface: BoundedGene

Create a new gene from the given value and the current bounds.

Specified by:

newInstance in interface BoundedGene<BigInteger, BigIntegerGene>

Specified by:

newInstance in interface Gene<BigInteger, BigIntegerGene>

Parameters:

value - the value of the new gene.

Returns:

a new gene with the given value.

newInstance

public BigIntegerGene newInstance()

Description copied from interface: Gene

Return a new, random gene with the same type and with the same constraints as this gene. For all genes returned by this method holds gene.getClass() == gene.newInstance().getClass(). Implementations of this method have to use the RandomGenerator object which can be fetched from the RandomRegistry.

Specified by:

newInstance in interface Factory<BigIntegerGene>

Specified by:

newInstance in interface Gene<BigInteger, BigIntegerGene>

Returns:

a new instance of type T

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object

of

public static BigIntegerGene of(BigInteger value,
 BigInteger min,
 BigInteger max)

Create a new random BigIntegerGene with the given value and the given range. If the value isn't within the interval [min, max), no exception is thrown. In this case the method BoundedGene.isValid() returns false.

Parameters:

value - the value of the gene.

min - the minimal valid value of this gene (inclusively).

max - the maximal valid value of this gene (exclusively).

Returns:

a new random BigIntegerGene

Throws:

NullPointerException - if one of the arguments is null

of

public static BigIntegerGene of(BigInteger min,
 BigInteger max)

Create a new random BigIntegerGene. It is guaranteed that the value of the BigIntegerGene lies in the interval [min, max).

Parameters:

min - the minimal valid value of this gene (inclusively).

max - the maximal valid value of this gene (exclusively).

Returns:

a new random BigIntegerGene

Throws:

NullPointerException - if one of the arguments is null
