* \brief qx::IxPersistable : common interface (abstract class) for persistents classes using QX_PERSISTABLE_HPP() and QX_PERSISTABLE_CPP() macros
|
|
*
|
|
* To use this common interface for persistents classes : <br>
|
|
* <b>1-</b> inherit your persistent class from <i>qx::IxPersistable</i> ; <br>
|
|
* <b>2-</b> into your class definition (<i>myClass.h</i> for example), add <i>QX_PERSISTABLE_HPP(myClass)</i> macro ; <br>
|
|
* <b>3-</b> into your class implementation (<i>myClass.cpp</i> for example), add <i>QX_PERSISTABLE_CPP(myClass)</i> macro.
|
|
*
|
|
* <b>Note :</b> for a list of objects (<i>qxFetchAll()</i> method or <i>qxFetchByQuery()</i> method), use <i>qx::QxCollection<type_primary_key, std::shared_ptr<my_type>></i> type.
|
|
* Or just use <i>qx::QxPersistableCollectionHelper<T>::type</i> to retrieve your persistent collection type.
|
|
* A convenient way to fetch a list of objects is to use following static methods <i>qxFetchAll()</i> and <i>qxFetchByQuery()</i> :
|
|
* \code
|
|
std::shared_ptr<qx::IxPersistableCollection> lst = qx::IxPersistable::qxFetchAll("myClass");
|
|
for (long l = 0; l < lst->_count(); l++)
|
|
{ qx::IxPersistable_ptr ptr = lst->_get<qx::IxPersistable_ptr>(l); etc... }
|
|
* \endcode
