Interface NumberType

All Superinterfaces:

com.davisor.core.Dupable

All Known Implementing Classes:

RelativeTimestampType, SimpleNumberType

public interface NumberType

extends com.davisor.core.Dupable

NumberType defines a base interface for all data types that manipulatae simple numeric values. As with all the other types, one of the main functions of all classes that implement NumberType is to convert number strings to number objects and back.

This interface defines the following operation sets:

• string to number conversions
• number to string conversions
• number to number conversions

The principal reference implementation for this interface is the SimpleNumberType clas.

Since:

JDK1.2
