All Implemented Interfaces:

Serializable, Cloneable

public class SafeSimpleDateFormat
extends DateFormat

This class implements a Thread-Safe (re-entrant) SimpleDateFormat class. It does this by using a ThreadLocal that holds a Map, instead of the traditional approach to hold the SimpleDateFormat in a ThreadLocal. Each ThreadLocal holds a single HashMap containing SimpleDateFormats, keyed by a String format (e.g. "yyyy/M/d", etc.), for each new SimpleDateFormat instance that was created within the threads execution context.
