Examples of org.apache.wicket.util.string.AppendingStringBuffer

org.apache.wicket.util.string.AppendingStringBuffer
This is a copy or combination of java.lang.StringBuffer and java.lang.String It has a special method getValue() which returns the internal char array. Hashcode and equals methods are also implemented. This AppendingStringBuffer is not synchronized. @author Johan Compagner @see java.lang.StringBuffer
