Package Summary Overview Summary

### class:DefaultListModel [NONE]
- Type Parameters: `E` - the type of the elements of this model All Implemented Interfaces: Serializable, ListModel<E>
      public class DefaultListModel<E>
      extends AbstractListModel<E>
This class loosely implements the `java.util.Vector` API, in that it implements the 1.1.x version of `java.util.Vector`, has no collection class support, and notifies the `ListDataListener`s when changes occur. Presently it delegates to a `Vector`, in a future release it will be a real Collection implementation. Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the `java.beans` package. Please see `XMLEncoder`. Since: 1.2

### method:getSize() [NONE]
- #### getSize
      public int getSize()

Parameters: `index` - an index into this list Returns: the component at the specified index Throws: `ArrayIndexOutOfBoundsException` - if the `index` is negative or greater than the current size of this list See Also: `get(int)`

### method:copyInto(java.lang.Object[]) [NONE]
- #### copyInto
      public void copyInto(Object[] anArray)
