| Methods Summary |
|---|
| public static void | commitContentPrefixList()Make changes to the content prefix-list persistent.
This method throws a SecurityException if the calling thread
does not have access to system properties.
if (pm != null && mCommitContentPrefixList != null) {
runMethod(mCommitContentPrefixList, null);
}
|
| public static void | commitProtocolPrefixList()Make changes to the protocol package-prefix list persistent.
This method throws a SecurityException if the calling thread
does not have access to system properties.
if (pm != null && mCommitProtocolPrefixList != null) {
runMethod(mCommitProtocolPrefixList, null);
}
|
| public static java.util.Vector | getContentPrefixList()Get the current value of the content package-prefix list.
Any changes made to this list take effect immediately.
// Default value
contentPrefixList = new Vector();
contentPrefixList.addElement("javax");
contentPrefixList.addElement("com.sun");
if (pm != null && mGetContentPrefixList != null) {
return (Vector) runMethod(mGetContentPrefixList, null);
} else
return contentPrefixList;

| static java.lang.reflect.Method | getDeclaredMethod(java.lang.Class c, java.lang.String name, java.lang.Class[] params)netscape browser throws SecurityException when you call
Class.getDeclaredMethod or Class.getDeclaredMethods
There is a privilege called UniversalMemberAccess which should
allow this call. But Netscape has disabled this privilege; they
mention this in in their security faq. So, we call getMethod and
using getDeclaringClass method, check to see if it the subclass
overrided it or not.
Note: this code is used in all cases, not just netscape
Method m = c.getMethod(name, params);
if (m.getDeclaringClass() == c) {
return m;
} else {
return null;
