| Aspect declarations are supported by the | |
| <tt>org.aspectj.lang.annotation.Aspect</tt> | |
| annotation. | |
| The declaration: | |
| </p><pre class="programlisting"> | |
| @Aspect | |
| public class Foo {} | |
| </pre><p>Is equivalent to:</p><pre class="programlisting"> | |
| public aspect Foo {} | |
| </pre><p>To specify an aspect an aspect instantiation model (the default is | |
| singleton), provide the perclause as the | |
| <tt>@Aspect</tt> | |
| value. | |
| For example: | |
| </p><pre class="programlisting"> | |
| @Aspect("perthis(execution(* abc..*(..)))") | |
| public class Foo {} | |
| </pre><p>is equivalent to...</p><pre class="programlisting"> | |
| public aspect Foo perthis(execution(* abc..*(..))) {} | |
