Interface NumberFactory

All Known Implementing Classes:

DoubleNumberFactory

public interface NumberFactory

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.

Object	createNumber(float value) Create a number object with given float value
Object	createNumber(int value) Create a number object with given int value
Object	createNumber(Number value) Creates a number object from a class implementing Number, May actually just return the class.
Object	createNumber(short value) Create a number object with given short value
Object	createNumber(String value) Creates a number object and initializes its value.
Object	getMinusOne() Return an object representing ZERO-ONE.
Object	getOne() Return an object representing ONE the multiplicative identity.
Object	getTwo() Return an object representing ONE+ONE.
Object	getZero() Return an object representing ZERO the additive identity.
