| <FONT color="green">030</FONT> /**<a name="line.30"></a> |
| <FONT color="green">031</FONT> * A <code>WildcardPermission</code> is a very flexible permission construct supporting multiple levels of<a name="line.31"></a> |
| <FONT color="green">032</FONT> * permission matching. However, most people will probably follow some standard conventions as explained below.<a name="line.32"></a> |
| <FONT color="green">033</FONT> * <p/><a name="line.33"></a> |
| <FONT color="green">034</FONT> * <h3>Simple Usage</h3><a name="line.34"></a> |
| <FONT color="green">035</FONT> * <p/><a name="line.35"></a> |
| <FONT color="green">036</FONT> * In the simplest form, <code>WildcardPermission</code> can be used as a simple permission string. You could grant a<a name="line.36"></a> |
| <FONT color="green">037</FONT> * user an &quot;editNewsletter&quot; permission and then check to see if the user has the editNewsletter<a name="line.37"></a> |
| <FONT color="green">038</FONT> * permission by calling<a name="line.38"></a> |
| <FONT color="green">039</FONT> * <p/><a name="line.39"></a> |
| <FONT color="green">040</FONT> * <code>subject.isPermitted(&quot;editNewsletter&quot;)</code><a name="line.40"></a> |
| <FONT color="green">041</FONT> * <p/><a name="line.41"></a> |
| <FONT color="green">042</FONT> * This is (mostly) equivalent to<a name="line.42"></a> |
| <FONT color="green">043</FONT> * <p/><a name="line.43"></a> |
| <FONT color="green">044</FONT> * <code>subject.isPermitted( new WildcardPermission(&quot;editNewsletter&quot;) )</code><a name="line.44"></a> |
| <FONT color="green">045</FONT> * <p/><a name="line.45"></a> |
| <FONT color="green">046</FONT> * but more on that later.<a name="line.46"></a> |
| <FONT color="green">047</FONT> * <p/><a name="line.47"></a> |
| <FONT color="green">048</FONT> * The simple permission string may work for simple applications, but it requires you to have permissions like<a name="line.48"></a> |
| <FONT color="green">049</FONT> * <code>&quot;viewNewsletter&quot;</code>, <code>&quot;deleteNewsletter&quot;</code>,<a name="line.49"></a> |
| <FONT color="green">050</FONT> * <code>&quot;createNewsletter&quot;</code>, etc. You can also grant a user <code>&quot;*&quot;</code> permissions<a name="line.50"></a> |
| <FONT color="green">051</FONT> * using the wildcard character (giving this class its name), which means they have <em>all</em> permissions. But<a name="line.51"></a> |
| <FONT color="green">052</FONT> * using this approach there's no way to just say a user has &quot;all newsletter permissions&quot;.<a name="line.52"></a> |
| <FONT color="green">053</FONT> * <p/><a name="line.53"></a> |
| <FONT color="green">054</FONT> * For this reason, <code>WildcardPermission</code> supports multiple <em>levels</em> of permissioning.<a name="line.54"></a> |
| <FONT color="green">055</FONT> * <p/><a name="line.55"></a> |
| <FONT color="green">056</FONT> * <h3>Multiple Levels</h3><a name="line.56"></a> |
| <FONT color="green">057</FONT> * <p/><a name="line.57"></a> |
| <FONT color="green">058</FONT> * WildcardPermission</code> also supports the concept of multiple <em>levels</em>. For example, you could<a name="line.58"></a> |
| <FONT color="green">059</FONT> * restructure the previous simple example by granting a user the permission <code>&quot;newsletter:edit&quot;</code>.<a name="line.59"></a> |
| <FONT color="green">060</FONT> * The colon in this example is a special character used by the <code>WildcardPermission</code> that delimits the<a name="line.60"></a> |
| <FONT color="green">061</FONT> * next token in the permission.<a name="line.61"></a> |
| <FONT color="green">062</FONT> * <p/><a name="line.62"></a> |
| <FONT color="green">063</FONT> * In this example, the first token is the <em>domain</em> that is being operated on<a name="line.63"></a> |
| <FONT color="green">064</FONT> * and the second token is the <em>action</em> being performed. Each level can contain multiple values. So you<a name="line.64"></a> |
| <FONT color="green">065</FONT> * could simply grant a user the permission <code>&quot;newsletter:view,edit,create&quot;</code> which gives them<a name="line.65"></a> |
| <FONT color="green">066</FONT> * access to perform <code>view</code>, <code>edit</code>, and <code>create</code> actions in the <code>newsletter</code><a name="line.66"></a> |
| <FONT color="green">067</FONT> * <em>domain</em>. Then you could check to see if the user has the <code>&quot;newsletter:create&quot;</code><a name="line.67"></a> |
| <FONT color="green">068</FONT> * permission by calling<a name="line.68"></a> |
| <FONT color="green">069</FONT> * <p/><a name="line.69"></a> |
| <FONT color="green">070</FONT> * <code>subject.isPermitted(&quot;newsletter:create&quot;)</code><a name="line.70"></a> |
| <FONT color="green">071</FONT> * <p/><a name="line.71"></a> |
| <FONT color="green">072</FONT> * (which would return true).<a name="line.72"></a> |
| <FONT color="green">073</FONT> * <p/><a name="line.73"></a> |
| <FONT color="green">074</FONT> * In addition to granting multiple permissions via a single string, you can grant all permission for a particular<a name="line.74"></a> |
| <FONT color="green">075</FONT> * level. So if you wanted to grant a user all actions in the <code>newsletter</code> domain, you could simply give<a name="line.75"></a> |
| <FONT color="green">076</FONT> * them <code>&quot;newsletter:*&quot;</code>. Now, any permission check for <code>&quot;newsletter:XXX&quot;</code><a name="line.76"></a> |
| <FONT color="green">077</FONT> * will return <code>true</code>. It is also possible to use the wildcard token at the domain level (or both): so you<a name="line.77"></a> |
| <FONT color="green">078</FONT> * could grant a user the <code>&quot;view&quot;</code> action across all domains <code>&quot;*:view&quot;</code>.<a name="line.78"></a> |
| <FONT color="green">079</FONT> * <p/><a name="line.79"></a> |
| <FONT color="green">080</FONT> * <h3>Instance-level Access Control</h3><a name="line.80"></a> |
| <FONT color="green">081</FONT> * <p/><a name="line.81"></a> |
| <FONT color="green">082</FONT> * Another common usage of the <code>WildcardPermission</code> is to model instance-level Access Control Lists.<a name="line.82"></a> |
| <FONT color="green">083</FONT> * In this scenario you use three tokens - the first is the <em>domain</em>, the second is the <em>action</em>, and<a name="line.83"></a> |
| <FONT color="green">084</FONT> * the third is the <em>instance</em> you are acting on.<a name="line.84"></a> |
| <FONT color="green">085</FONT> * <p/><a name="line.85"></a> |
| <FONT color="green">086</FONT> * So for example you could grant a user <code>&quot;newsletter:edit:12,13,18&quot;</code>. In this example, assume<a name="line.86"></a> |
| <FONT color="green">087</FONT> * that the third token is the system's ID of the newsletter. That would allow the user to edit newsletters<a name="line.87"></a> |
| <FONT color="green">088</FONT> * <code>12</code>, <code>13</code>, and <code>18</code>. This is an extremely powerful way to express permissions,<a name="line.88"></a> |
| <FONT color="green">089</FONT> * since you can now say things like <code>&quot;newsletter:*:13&quot;</code> (grant a user all actions for newsletter<a name="line.89"></a> |
| <FONT color="green">090</FONT> * <code>13</code>), <code>&quot;newsletter:view,create,edit:*&quot;</code> (allow the user to<a name="line.90"></a> |
| <FONT color="green">091</FONT> * <code>view</code>, <code>create</code>, or <code>edit</code> <em>any</em> newsletter), or<a name="line.91"></a> |
| <FONT color="green">092</FONT> * <code>&quot;newsletter:*:*</code> (allow the user to perform <em>any</em> action on <em>any</em> newsletter).<a name="line.92"></a> |
| <FONT color="green">093</FONT> * <p/><a name="line.93"></a> |
| <FONT color="green">094</FONT> * To perform checks against these instance-level permissions, the application should include the instance ID in the<a name="line.94"></a> |
| <FONT color="green">095</FONT> * permission check like so:<a name="line.95"></a> |
| <FONT color="green">096</FONT> * <p/><a name="line.96"></a> |
| <FONT color="green">097</FONT> * <code>subject.isPermitted( &quot;newsletter:edit:13&quot; )</code><a name="line.97"></a> |
| <FONT color="green">098</FONT> * <p/><a name="line.98"></a> |
| <FONT color="green">099</FONT> * There is no limit to the number of tokens that can be used, so it is up to your imagination in terms of ways that<a name="line.99"></a> |
| <FONT color="green">100</FONT> * this could be used in your application. However, the Shiro team likes to standardize some common usages shown<a name="line.100"></a> |
| <FONT color="green">101</FONT> * above to help people get started and provide consistency in the Shiro community.<a name="line.101"></a> |
