Class GrowableIntArray

  • public class GrowableIntArray
extends Object
    Growable int array with type specific access methods. This implementation is unsynchronized in order to provide the best possible performance for typical usage scenarios, so explicit synchronization must be implemented by a wrapper class or directly by the application in cases where instances are modified in a multithreaded environment.
