+# Hook
+
+Minimalist, annotation based, hook framework for Java/Android built on top of [AspectJ](https://eclipse.org/aspectj/).
+
+# Basic Usage
+
+```java
+
+public class Math {
+
+    @Hooked("my_hook")
+    public int add(int a,int b) {
+        return a+b;
+    }
+}
+
+public class IncrementHook {
+
+    @Hook("my_hook")
+    int hook(HookedMethod<Integer> method) throws Throwable {
+        return method.proceed() + 1; // add one 
+    }
+}
+
+final Math math = new Math();
+final IncrementHook hook = new IncrementHook();
+
+Hooker.instance().register(hook);
+assertThat(math.add(5, 3), is(9)); // 5 + 3 = 9
+Hooker.instance().unregister(hook);
+assertThat(math.add(5, 3), is(8)); // 5 + 3 = 8    
+
+```
+
+# Advanced Usage
+
+```java
+
+public class Math {
+
+    @Hooked("my_hook")
+    public int add(@Param("a") int a, @Param("b") int b) {
+        System.out.println("    calling add("+a+", "+b+")");
+        return a+b;
+    }
+}
+
+public class Hooks {
+
+	@Before("my_hook")
+    void before(int a, int b) {
+        System.out.println("  @Before(a="+a+", b="+b+")");
+    }
+
+    @Call("my_hook")
+    void call(int a, int b) {
+        System.out.println("@Call(a="+a+", b="+b+")");
+    }
+
+    @After("my_hook")
+    void after(@Param("a") int a, @Param("b") int b, @Target Math math, @Result int result) {
+        System.out.println("  @After(a="+a+", b="+b+", result="+result+")");
+    }
+
+    @Returning("my_hook")
+    void returning(@Param("a") int a, @Param("b") int b, @Result int result) {
+        System.out.println("@Returning(a="+a+", b="+b+", result="+result+")");
+    }
+
+    @Hook("my_hook")
+    int hook(HookedMethod<Integer> method, @Param("a") int a, @Param("b") int b, @Target Math math) throws Throwable {
+        System.out.println("entering @Hook(a="+a+", b="+b+")");
+        int ret = method.proceed(2*a, 2*b) + 1; // double operands and increment result
+        System.out.println("exiting @Hook (return "+ret+")");
+        return ret;
+    }
+}
+
+final Math math = new Math();
+final Hooks hook = new Hooks();
+
+Hooker.instance().register(hook);
+assertThat(math.add(5, 3), is(17));
+Hooker.instance().unregister(hook);
+```
+
+For clarity, here's the output of the snippet above :
+
+```
+@Call(a=5, b=3)
+entering @Hook(a=5, b=3)
+  @Before(a=10, b=6)
+    calling add(10, 6)
+  @After(a=10, b=6, result=16)
+exiting @Hook (return 17)
+@Returning(a=10, b=6, result=17)
+```
