Class GrowableIntArray

java.lang.Object
  org.jibx.runtime.impl.GrowableIntArray

public class GrowableIntArray
extends java.lang.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.
