<DL>
<DD>Converts an array of bytes into an instance of class Class,
 with an optional CodeSource. Before the
 class can be used it must be resolved.
 <p>
 If a non-null CodeSource is supplied and a Policy provider is installed,
 Policy.getPermissions() is invoked in order to associate a
 ProtectionDomain with the class being defined.

<PRE>
protected <A HREF="../../java/security/PermissionCollection.html">PermissionCollection</A> <B>getPermissions</B>(<A HREF="../../java/security/CodeSource.html">CodeSource</A>&nbsp;codesource)</PRE>
<DL>
<DD>Returns the permissions for the given CodeSource object.
 The default implementation of this method invokes the
 java.security.Policy.getPermissions method to get the permissions
 granted by the policy to the specified CodeSource.
 <p>
 This method is invoked by the defineClass method which takes
 a CodeSource as an argument when it is constructing the
 ProtectionDomain for the class being defined.
 <p>
 The constructed ProtectionDomain is cached by the SecureClassLoader.
 The contents of the cache persist for the lifetime of the
 SecureClassLoader instance. This persistence inhibits Policy.refresh()
 from influencing the protection domains already in the cache for a 
 given CodeSource.
