When the OsclExclusiveArrayPtr expires, its destructor uses delete to free the memory. 46 <p> 47 The purpose of this class is to provide a way to prevent accidental memory leaks in a class or a method, due to "not remembering to delete" variables allocated on the heap. Thus if you assign an address returned by new to an <a class="el" href="classOsclExclusivePtr.html">OsclExclusivePtr</a> object, you don't have to remember to free the memory later, it will be freed automatically when the object goes out of scope. The <a class="el" href="classOsclExclusivePtr.html">OsclExclusivePtr</a> is an example of a smart pointer, an object that acts like a pointer, but with additional features. The class is defined so that it acts like a regular pointer in most respects 48 <p> 49 <hr><h2>Constructor & Destructor Documentation</h2> 50 <a name="a0" doxytag="OsclExclusiveArrayPtr::OsclExclusiveArrayPtr"></a><p> 51 <table width="100%" cellpadding="2" cellspacing="0" border="0"> 52 <tr> 53 <td class="md"> 54 <table cellpadding="0" cellspacing="0" border="0"> 55 <tr> 56 <td class="md" colspan="4"> 57 template<class T> </td> 58 </tr> 59 <tr> 60 <td class="md" nowrap valign="top"> OsclExclusiveArrayPtr< T >::OsclExclusiveArrayPtr </td> 61 <td class="md" valign="top">( </td> 62 <td class="md" nowrap valign="top">T * </td> 63 <td class="mdname1" valign="top" nowrap> <em>inPtr</em> = 0 </td> 64 <td class="md" valign="top">) </td> 65 <td class="md" nowrap><code> [inline, explicit]</code></td> 66 </tr> 67 68 </table> 69 </td> 70 </tr> 71 </table> 72 <table cellspacing=5 cellpadding=0 border=0> 73 <tr> 74 <td> 75 76 </td> 77 <td> 78 79 <p> 80 Default constructor Initializes the pointer and takes ownership. 81 <p> 82 </td> 83 </tr> 84 </table> 85 <a name="a1" doxytag="OsclExclusiveArrayPtr::OsclExclusiveArrayPtr"></a><p> 86 <table width="100%" cellpadding="2" cellspacing="0" border="0"> 87 <tr> 88 <td class="md"> 89 <table cellpadding="0" cellspacing="0" border="0"> 90 <tr> 91 <td class="md" colspan="4"> 92 template<class T> </td> 93 </tr> 94 <tr> 95 <td class="md" nowrap valign="top"> OsclExclusiveArrayPtr< T >::OsclExclusiveArrayPtr </td> 96 <td class="md" valign="top">( </td> 97 <td class="md" nowrap valign="top">OsclExclusiveArrayPtr< T > & </td> 98 <td class="mdname1" valign="top" nowrap> <em>_Y</em> </td> 99 <td class="md" valign="top">) </td> 100 <td class="md" nowrap><code> [inline]</code></td> 101 </tr> 102 103 </table> 104 </td> 105 </tr> 106 </table> 107 <table cellspacing=5 cellpadding=0 border=0> 108 <tr> 109 <td> 110 111 </td> 112 <td> 113 114 <p> 115 Copy constructor. 116 <p> 117 Initializes the pointer and takes ownership from another OsclExclusiveArrayPtr.
