## com.singularsys.jep
Interface NumberFactory

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.

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