    • getSize

      public int getSize()
      Returns the number of components in this list.

      This method is identical to size, which implements the List interface defined in the 1.2 Collections framework. This method exists in conjunction with setSize so that size is identifiable as a JavaBean property.

      Returns:
      the number of components in this list

    • getElementAt

      public Object getElementAt(int index)
      Returns the component at the specified index.
      Note: Although this method is not deprecated, the preferred method to use is get(int), which implements the List interface defined in the 1.2 Collections framework.
      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:

    • copyInto

      public void copyInto(Object[] anArray)
