Class ThreadSafeSimpleDateFormat

  • public class ThreadSafeSimpleDateFormat
extends java.lang.Object
    Wrapper around java.text.SimpleDateFormat that can be called by multiple threads concurrently.

    SimpleDateFormat has a high overhead in creating and is not thread safe. To make best use of resources, the ThreadSafeSimpleDateFormat provides a dynamically sizing pool of instances, each of which will only be called by a single thread at a time.

    The pool has a maximum capacity, to limit overhead. If all instances in the pool are in use and another is required, it shall block until one becomes available.
