 resolved a given (base, property) pair.

 <p>The <A HREF="../../javax/el/CompositeELResolver.html" title="class in javax.el"><CODE>CompositeELResolver</CODE></A> checks this property to determine

<DD>Associates a context object with this <code>ELContext</code>.

 <p>The <code>ELContext</code> maintains a collection of context objects
 relevant to the evaluation of an expression. These context objects
 are used by <code>ELResolver</code>s.  This method is used to
 add a context object to that collection.</p>

 type specified by the <code>key</code>.  However, this is not
 required and the key is used strictly as a unique identifier.</p>

 <p>The <code>ELContext</code> maintains a reference to the 
 <code>ELResolver</code> that will be consulted to resolve variables

 retrieves the reference to the resolver.</p>

 <p>Once an <code>ELContext</code> is constructed, the reference to the
 <code>ELResolver</code> associated with the context cannot be changed.</p>
