Class VariableNameGenerator

java.lang.Object
  org.sadun.util.codegen.VariableNameGenerator

public class VariableNameGenerator

extends java.lang.Object

A class to generate variable names depending on types.

Given a method name and a Java type, the generateNext() method produces valid (i.e. compilable) sequences of variable names, depending on the passed type, until either a different method name is passed or the reset() method is invoked.

For example, the invocations:

  generateNext("myMethod", t1);
  generateNext("myMethod", t2);
  generateNext("myMethod", t3);
 

where t1=String, t2=int, t3=String will produce string1, i1, string2.

This generator supports both JDK1.3 and JDK1.4 keywords.
