public final class LongGene
extends Object
implements NumericGene<Long,LongGene>, Mean<LongGene>, Comparable<LongGene>, Serializable

NumericGene implementation which holds a 64-bit integer number.

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

Since:

1.6

Version:

6.1

Implementation Note:

This class is immutable and thread-safe.
