<P>
Factory class that Rhino runtime uses to create new <A HREF="../../../org/mozilla/javascript/Context.html" title="class in org.mozilla.javascript"><CODE>Context</CODE></A>
 instances.  A <code>ContextFactory</code> can also notify listeners
 about context creation and release.
 <p>
 When the Rhino runtime needs to create new <A HREF="../../../org/mozilla/javascript/Context.html" title="class in org.mozilla.javascript"><CODE>Context</CODE></A> instance during
 execution of <A HREF="../../../org/mozilla/javascript/Context.html#enter()"><CODE>Context.enter()</CODE></A> or <A HREF="../../../org/mozilla/javascript/Context.html" title="class in org.mozilla.javascript"><CODE>Context</CODE></A>, it will call
 <A HREF="../../../org/mozilla/javascript/ContextFactory.html#makeContext()"><CODE>makeContext()</CODE></A> of the current global ContextFactory.
 See <A HREF="../../../org/mozilla/javascript/ContextFactory.html#getGlobal()"><CODE>getGlobal()</CODE></A> and <A HREF="../../../org/mozilla/javascript/ContextFactory.html#initGlobal(org.mozilla.javascript.ContextFactory)"><CODE>initGlobal(ContextFactory)</CODE></A>.
 <p>
 It is also possible to use explicit ContextFactory instances for Context
 creation. This is useful to have a set of independent Rhino runtime
 instances under single JVM. See <A HREF="../../../org/mozilla/javascript/ContextFactory.html#call(org.mozilla.javascript.ContextAction)"><CODE>call(ContextAction)</CODE></A>.
 <p>
 The following example demonstrates Context customization to terminate
 scripts running more then 10 seconds and to provide better compatibility
 with JavaScript code using MSIE-specific features.
 <pre>
 import org.mozilla.javascript.*;

 class MyFactory extends ContextFactory
 {

     // Custom <A HREF="../../../org/mozilla/javascript/Context.html" title="class in org.mozilla.javascript"><CODE>Context</CODE></A> to store execution time.
     private static class MyContext extends Context
     {
         long startTime;
     }

     static {
         // Initialize GlobalFactory with custom factory
         ContextFactory.initGlobal(new MyFactory());
     }

     // Override <A HREF="../../../org/mozilla/javascript/ContextFactory.html#makeContext()"><CODE>makeContext()</CODE></A>
     protected Context makeContext()
     {
         MyContext cx = new MyContext();
         // Use pure interpreter mode to allow for
         // <A HREF="../../../org/mozilla/javascript/ContextFactory.html#observeInstructionCount(org.mozilla.javascript.Context, int)"><CODE>observeInstructionCount(Context, int)</CODE></A> to work
         cx.setOptimizationLevel(-1);
         // Make Rhino runtime to call observeInstructionCount
         // each 10000 bytecode instructions
         cx.setInstructionObserverThreshold(10000);
         return cx;
     }

     // Override <A HREF="../../../org/mozilla/javascript/ContextFactory.html#hasFeature(org.mozilla.javascript.Context, int)"><CODE>hasFeature(Context, int)</CODE></A>
     public boolean hasFeature(Context cx, int featureIndex)
     {
         // Turn on maximum compatibility with MSIE scripts
         switch (featureIndex) {
             case <A HREF="../../../org/mozilla/javascript/Context.html#FEATURE_NON_ECMA_GET_YEAR"><CODE>Context.FEATURE_NON_ECMA_GET_YEAR</CODE></A>:
                 return true;

<DL>
<DD>Get a context associated with the current thread, creating one if need 
 be. The Context stores the execution state of the JavaScript engine, so 
 it is required that the context be entered before execution may begin. 
 Once a thread has entered a Context, then getCurrentContext() may be 
 called to find the context that is associated with the current thread.
 <p>
 Calling <code>enterContext()</code> will return either the Context 
 currently associated with the thread, or will create a new context and 
 associate it with the current thread. Each call to 
 <code>enterContext()</code> must have a matching call to 
 <A HREF="../../../org/mozilla/javascript/Context.html#exit()"><CODE>Context.exit()</CODE></A>.
 <pre>
      Context cx = contextFactory.enterContext();
      try {
          ...
          cx.evaluateString(...);
      } finally {
          Context.exit();
      }
 </pre>
 Instead of using <tt>enterContext()</tt>, <tt>exit()</tt> pair consider 
 using <A HREF="../../../org/mozilla/javascript/ContextFactory.html#call(org.mozilla.javascript.ContextAction)"><CODE>call(ContextAction)</CODE></A> which guarantees proper association 
 of Context instances with the current thread.
 With this method the above example becomes:
 <pre>
      ContextFactory.call(new ContextAction() {
          public Object run(Context cx) {
              ...
              cx.evaluateString(...);
              return null;
          }
      });
