 /**

  * using the property "javax.xml.stream.allocator"
  *
  * This base class uses EventFactory to create events as recommended in the JavaDoc of XMLEventAllocator.
  * However, creating new object per each event reduces performance. The implementation of
  * EventReader therefore will set the Allocator to StAXEventAllocator which implements the
  * Allocate methods without creating new objects.
  *
  * The spec for the first Allocate method states that it must NOT modify the state of the Reader
  * while the second MAY. For consistency, both Allocate methods in this implementation will
  * NOT modify the state.
