Zend Framework教程之Bootstrap类用法概述_php实例
本文实例讲述了Zend Framework中Bootstrap类用法。分享给大家供大家参考,具体如下:
Zend_Application_Bootstrap_Bootstrapper
Zend_Application_Bootstrap_Bootstrapper是所有引导类必须实现的基本接口。基本功能是用于配置,注册资源,引导(无论是单个资源或整个应用程序),并运行应用程序。
接口方法:
Zend_Application_Bootstrap_Bootstrapper Interface
Method | Return Value | Parameters | Description |
---|---|---|---|
__construct( $application ) |
Void |
|
构造方法。接受一个参数,参数要求是一个Zend_Application对象,或另一个引导对象。 |
setOptions( array $options) |
Zend_Application_Bootstrap_Bootstrapper |
|
通常情况下, 选项都可以匹配映射到对应的setter;否则,选项仅仅会被存储,便于以后查找 |
getApplication() | Zend_Application |Zend_Application_Bootstrap_Bootstrapper | N/A |
获取application实例 |
getEnvironment() | String | N/A |
获取environment |
getClassResources() | Array | N/A |
获取可以可用的资源 |
bootstrap($resource = null) | Mixed |
|
如果 $resource为空,注册所有资源.如果为字符串注册指定的资源;如果是数组, 只注册指定的资源. |
run() | Void | N/A |
执行引导. |
Zend_Application_Bootstrap_ResourceBootstrapper
Zend_Application_Bootstrap_ResourceBootstrapper是一个接口,用于引导类加载注册外部资源 。 也就是说,一个或多个资源不会直接在类中定义,而是通过插件形式引入。它应该与Zend_Application_Bootstrap_Bootstrapper结合使用; Zend_Application_Bootstrap_BootstrapAbstract实现了这个功能。
接口方法:
Zend_Application_Bootstrap_ResourceBootstrapper Interface
Method | Return Value | Parameters | Description |
---|---|---|---|
registerPluginResource($resource, $options = null) | Zend_Application_Bootstrap_ResourceBootstrapper |
|
用于注册资源类,通过可选选项传递资源 |
unregisterPluginResource($resource) | Zend_Application_Bootstrap_ResourceBootstrapper |
|
删除插件资源 |
hasPluginResource($resource) | Boolean |
|
|
getPluginResource($resource) | Zend_Application_Resource_Resource |
|
|
getPluginResourceNames() | Array | N/A |
|
setPluginLoader(Zend_Loader_PluginLoader_Interface $loader) | Zend_Application_Bootstrap_ResourceBootstrapper |
|
|
getPluginLoader() | Zend_Loader_PluginLoader_Interface | N/A |
|
Zend_Application_Bootstrap_BootstrapAbstract
Zend_Application_Bootstrap_BootstrapAbstract是一个抽象类,它提供了一个通用的引导基本功能。它实现了Zend_Application_Bootstrap_Bootstrapper和Zend_Application_Bootstrap_ResourceBootstrapper。
Zend_Application_Bootstrap_BootstrapAbstract Methods
Method | Return Value | Parameters | Description |
---|---|---|---|
__construct($application) | Void |
|
Accepts either a Zend_Application or a Zend_Application_Bootstrap_Bootstrapper object as the sole argument. |
setOptions(array $options) | Zend_Application_Bootstrap_Bootstrapper |
|
所有选项都可以映射到选项指定的setter, 否则,该选项将只是被存储供以后查找 例如,如果在扩展类中定义一个setFoo() 方法,可以通过foo选项传递值 |
getOptions() | Array | N/A |
|
hasOption($key) | Boolean |
|
|
getOption($key) | Mixed |
|
不存在返回 NULL |
setApplication(Zend_Application | Zend_Application_Bootstrap_Bootstrapper $application) | Zend_Application_Bootstrap_BootstrapAbstract |
|
|
getApplication() | Zend_Application |Zend_Application_Bootstrap_Bootstrapper | N/A |
|
getEnvironment() | String | N/A |
|
getClassResources() | Array | N/A |
|
getContainer() | Object | N/A |
获取存储资源的容器。如果没有容器,可以通过Zend_Registry注册,然后返回一个Zend_Registry实例。 |
setContainer($container) | Zend_Application_Bootstrap_BootstrapAbstract |
|
|
hasResource($name) | Boolean |
|
|
getResource($name) | Mixed |
|
|
bootstrap($resource = null) | Mixed |
|
如果 $resource为空,注册所有资源.如果为字符串注册指定的资源;如果是数组, 只注册指定的资源. |
run() | Void | N/A |
|
__call($method, $args) | Mixed |
|
为了方便可以用'bootstrap |
Zend_Application_Bootstrap_Bootstrap
Zend_Application_Bootstrap_Bootstrap是Zend_Application_Bootstrap_BootstrapAbstract具体实现。它的主要功能是,注册资源,然后运行 run() 方法。
在大多数情况下,你可以根据自己的引导需求继承这个类或直接使用这个类,并来注册资源插件。
启用 Application 自动加载功能
此外,该引导的实现提供了自动加载指定“命名空间”或指定资源类的前缀的功能
本质上,它实例化一个Zend_Application_Module_Autoloader的对象,参数为命名空间和引导类的目录。可以开启这个功能,通过 “appnamespace”配置选项设置命名空间。
As an INI example:
appnamespace = "Application"
Or in XML:
<appnamespace>Application</appnamespace>
默认情况下,Zend_Tool提供“Application”命名空间。
或者,可以在bootstrap类中通过$_appNamespace属性指定命名空间。
class Bootstrap extends Zend_Application_Bootstrap_Bootstrap { protected $_appNamespace = 'Application'; }
