abstract
</H1>
<P>
<SPAN CLASS="textbf">OOP concept:</SPAN> Abstract describes something
that is declared but not fully defined. For example, an abstract
method is a method that is declared as a part of a class, but has no
implementation. It cannot be called, it is only meant to be
inherited by derived classes.
<BR>
<P>
<SPAN CLASS="textbf">SIDL keyword:</SPAN> Abstract is an optional modifier for both
<TT><I CLASS="slanted">class</I></TT>es and <TT><I CLASS="slanted">method</I></TT>s. An abstract method is a method
that has no implementation, it's a way of declaring a method that
every subclass must implement for itself. An abstract class has one
or more abstract methods, and therefore cannot be instantiated.
