Direct Known Subclasses:

NumericIdProperty

public class NumericProperty<E extends Number>
extends BaseProperty<E>
implements ComparableProperty<E>

Property that represents attributes mapped on numeric types

Numeric type is an any type inherited from Number.

Provides basic math functions like mod(Number), abs() and sqrt(). It is also implements ComparableProperty interface.
