<pre>public interface <a href="../../../../src-html/org/apache/shiro/authz/Authorizer.html#line.48">Authorizer</a></pre>
<div class="block">An <tt>Authorizer</tt> performs authorization (access control) operations for any given Subject
(aka 'application user').
<p>Each method requires a subject principal to perform the action for the corresponding Subject/user.
<p>This principal argument is usually an object representing a user database primary key or a String username or
something similar that uniquely identifies an application user. The runtime value of the this principal
is application-specific and provided by the application's configured Realms.
<p>Note that there are many *Permission methods in this interface overloaded to accept String arguments instead of
<a href="../../../../org/apache/shiro/authz/Permission.html" title="interface in org.apache.shiro.authz"><code>Permission</code></a> instances. They are a convenience allowing the caller to use a String representation of
a <a href="../../../../org/apache/shiro/authz/Permission.html" title="interface in org.apache.shiro.authz"><code>Permission</code></a> if desired. Most implementations of this interface will simply convert these
String values to <a href="../../../../org/apache/shiro/authz/Permission.html" title="interface in org.apache.shiro.authz"><code>Permission</code></a> instances and then just call the corresponding type-safe method.
(Shiro's default implementations do String-to-Permission conversion for these methods using
<a href="../../../../org/apache/shiro/authz/permission/PermissionResolver.html" title="interface in org.apache.shiro.authz.permission"><code>PermissionResolver</code></a>s.)
<p>These overloaded *Permission methods <em>do</em> forego type-safety for the benefit of convenience and simplicity,
so you should choose which ones to use based on your preferences and needs.</div>
