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.
