checkPermission

void checkPermission(Permission perm,
                     Object context)

Throws a SecurityException if the specified security context is denied access to the resource specified by the given permission. The context must be a security context returned by a previous call to getSecurityContext and the access control decision is based upon the configured security policy for that security context.

If context is an instance of AccessControlContext then the AccessControlContext.checkPermission method is invoked with the specified permission.

If context is not an instance of AccessControlContext then a SecurityException is thrown.

参数:

perm - the specified permission

context - a system-dependent security context.

抛出:

SecurityException - if the specified security context is not an instance of AccessControlContext (e.g., is null), or is denied access to the resource specified by the given permission.

NullPointerException - if the permission argument is null.
