/** |

|
* Imports a class or a directory. |
||||||
|
* |
||||||
|
* Importing a class is like including the corresponding class file. |
||||||
|
* The main difference is that importing a class is much lighter because it only |
||||||
|
* includes the class file when the class is referenced the first time. |
||||||
|
* |
||||||
|
* Importing a directory is equivalent to adding a directory into the PHP include path. |
||||||
|
* If multiple directories are imported, the directories imported later will take |
||||||
|
* precedence in class file searching (i.e., they are added to the front of the PHP include path). |
||||||
|
* |
||||||
|
* Path aliases are used to import a class or directory. For example, |
||||||
|
* <ul> |
||||||
|
* <li><code>application.components.GoogleMap</code>: import the <code>GoogleMap</code> class.</li> |
||||||
|
* <li><code>application.components.*</code>: import the <code>components</code> directory.</li> |
||||||
|
* </ul> |
||||||
|
* |
||||||
|
* The same path alias can be imported multiple times, but only the first time is effective. |
||||||
|
* Importing a directory does not import any of its subdirectories. |
||||||
|
* |
||||||
|
* Starting from version 1.1.5, this method can also be used to import a class in namespace format |
||||||
|
* (available for PHP 5.3 or above only). It is similar to importing a class in path alias format, |
||||||
|
* except that the dot separator is replaced by the backslash separator. For example, importing |
||||||
|
* <code>application\components\GoogleMap</code> is similar to importing <code>application.components.GoogleMap</code>. |
||||||
|
* The difference is that the former class is using qualified name, while the latter unqualified. |
||||||
|
* |
||||||
|
* Note, importing a class in namespace format requires that the namespace is corresponding to |
||||||
|
* a valid path alias if we replace the backslash characters with dot characters. |
||||||
|
* For example, the namespace <code>application\components</code> must correspond to a valid |
||||||
|
* path alias <code>application.components</code>. |
||||||
|
* |
||||||
|
* @param string $alias path alias to be imported |
||||||
|
* @param boolean $forceInclude whether to include the class file immediately. If false, the class file |
||||||

||||||
|
* the path alias refers to a class. |
||||||

* @return string the class name or the directory that this alias refers to |
||||||
