Writing Advanced Applications
Appendix C: Security Manager Methods

[<<BACK] [CONTENTS] [NEXT>>]


This table shows which permissions are checked for by the
default implementations of the java.lang.SecurityManager
methods. Each of the check methods calls the
SecurityManager.checkPermission method with the indicated
permission, except for the checkConnect and checkRead
methods that take a context argument.
The checkConnect and checkRead
methods expect the context to be an AccessControlContext
and they call the context's checkPermission method
with the specified permission.
