All Superinterfaces:

JepComponent, java.io.Serializable

All Known Implementing Classes:

BigDecNumberFactory, DoubleNumberFactory

public interface NumberFactory
extends JepComponent

This interface can be implemented to create numbers of any object type. By implementing this interface and calling the setNumberFactory() method of the Jep class, the constants in an expression will be created with that class.
