34 * <p>A SubjectDelegationPermission contains a name (also referred
35 * to as a "target name") but no actions list; you either have the
36 * named permission or you don't.</p>
37 *
38 * <p>The target name is the name of the authorization principal
39 * classname followed by a period and the authorization principal
40 * name, that is
41 * <code>"<em>PrincipalClassName</em>.<em>PrincipalName</em>"</code>.</p>
42 *
43 * <p>An asterisk may appear by itself, or if immediately preceded
44 * by a "." may appear at the end of the target name, to signify a
45 * wildcard match.</p>
46 *
47 * <p>For example, "*", "javax.management.remote.JMXPrincipal.*" and
48 * "javax.management.remote.JMXPrincipal.delegate" are valid target
49 * names. The first one denotes any principal name from any principal
50 * class, the second one denotes any principal name of the concrete
51 * principal class <code>javax.management.remote.JMXPrincipal</code>
52 * and the third one denotes a concrete principal name
53 * <code>delegate</code> of the concrete principal class
54 * <code>javax.management.remote.JMXPrincipal</code>.</p>
