Class Operable<T extends Comparable<T>>

java.lang.Object

de.tsl2.nano.util.operation.Operable<T>

All Implemented Interfaces:

IOperable<T>

Direct Known Subclasses:

OperableUnit

public class Operable<T extends Comparable<T>>
extends Object
implements IOperable<T>

Standard operand providing operations through IOperable. it wraps the Comparable interface to become readable/usable. in other words: wraps any java-bean to be a comparable number.

if null-converter was given , only a constraint selection of operations are available.
