All Implemented Interfaces:

TypeConverter

public class NumberTypeConverter

extends BaseTypeConverter

This class is the main number converter. It is able to convert strings to primitive types or sub-classes of java.lang.Number. Primitive types are handled by conversion to the equivalent wrapper class. In most cases the valueOf method is used on the appropriate wrapper class in order to convert the string value. Since this class sub-classes BaseTypeConverter it is able to convert to and from arrays. See the parent for more information.
