| Binding member functions can be done similarly. A bound member function |
| takes in a pointer or reference to an object as the first argument. For |
| instance, given: |
| </p> |
| <pre class="programlisting"><span class="keyword">struct</span> <span class="identifier">xyz</span> |
| <span class="special">{</span> |
| <span class="keyword">void</span> <span class="identifier">foo</span><span class="special">(</span><span class="keyword">int</span><span class="special">)</span> <span class="keyword">const</span><span class="special">;</span> |
| <span class="special">};</span> |
| </pre> |
| <p> |
| <code class="computeroutput"><span class="identifier">xyz</span></code>'s <code class="computeroutput"><span class="identifier">foo</span></code> |
| member function can be bound as: |
| </p> |
| <pre class="programlisting"><span class="identifier">bind</span><span class="special">(&</span><span class="identifier">xyz</span><span class="special">::</span><span class="identifier">foo</span><span class="special">,</span> <span class="identifier">obj</span><span class="special">,</span> <span class="identifier">arg1</span><span class="special">)</span> <span class="comment">// obj is an xyz object |
| </span></pre> |
| <p> |
| Take note that a lazy-member functions expects the first argument to be |
| a pointer or reference to an object. Both the object (reference or pointer) |
| and the arguments can be lazily bound. Examples: |
| </p> |
| <pre class="programlisting"><span class="identifier">xyz</span> <span class="identifier">obj</span><span class="special">;</span> |
| <span class="identifier">bind</span><span class="special">(&</span><span class="identifier">xyz</span><span class="special">::</span><span class="identifier">foo</span><span class="special">,</span> <span class="identifier">arg1</span><span class="special">,</span> <span class="identifier">arg2</span><span class="special">)</span> <span class="comment">// arg1.foo(arg2) |
| </span><span class="identifier">bind</span><span class="special">(&</span><span class="identifier">xyz</span><span class="special">::</span><span class="identifier">foo</span><span class="special">,</span> <span class="identifier">obj</span><span class="special">,</span> <span class="identifier">arg1</span><span class="special">)</span> <span class="comment">// obj.foo(arg1) |
| </span><span class="identifier">bind</span><span class="special">(&</span><span class="identifier">xyz</span><span class="special">::</span><span class="identifier">foo</span><span class="special">,</span> <span class="identifier">obj</span><span class="special">,</span> <span class="number">100</span><span class="special">)</span> <span class="comment">// obj.foo(100) |
