34+ * This class is for various network permissions.
35+ * A NetPermission contains a name (also referred to as a "target name") but
36+ * no actions list; you either have the named permission
37+ * or you don't.
38+ * <P>
39+ * The target name is the name of the network permission (see below). The naming
40+ * convention follows the hierarchical property naming convention.
41+ * Also, an asterisk
42+ * may appear at the end of the name, following a ".", or by itself, to
43+ * signify a wildcard match. For example: "foo.*" or "*" is valid,
44+ * "*foo" or "a*b" is not valid.
45+ * <P>
46+ * The following table lists all the possible NetPermission target names,
47+ * and for each provides a description of what the permission allows
48+ * and a discussion of the risks of granting code the permission.
