public abstract class AbstractIntegerTransformer<T extends java.lang.Number>
extends NumberTransformerBase<T>

A base class for number transformers that operate on integer numbers.

This base class already implements the creation of the NumberFormat object used for parsing the entered numbers. Concrete sub classes specialize on specific integer types like java.lang.Integer or java.lang.Long.
