addAppHandler

public static void addAppHandler(CefAppHandler appHandler)
                          throws java.lang.IllegalStateException

Assign an AppHandler to CefApp. The AppHandler can be used to evaluate application arguments, to register your own schemes and to hook into the shutdown sequence. See CefAppHandler for more details. This method must be called before CefApp is initialized. CefApp will be initialized automatically if you call createClient() the first time. (将一个AppHandler分配给CefApp。 AppHandler可用于评估应用程序参数，注册您自己的方案并挂钩到关闭序列中。有关更多详细信息，请参见CefAppHandler。必须在初始化CefApp之前调用此方法。如果您第一次调用createClient（），则CefApp将自动初始化。)

参数:

appHandler - An instance of CefAppHandler. (-CefAppHandler的实例。)

抛出:

java.lang.IllegalStateException - in case of CefApp is already initialized

clearSchemeHandlerFactories

public boolean clearSchemeHandlerFactories()

Clear all registered scheme handler factories. Returns false on error. This function may be called on any thread in the browser process. (清除所有注册的方案处理程序工厂。错误时返回false。可以在浏览器进程中的任何线程上调用此函数。)

clientWasDisposed

protected final void clientWasDisposed(CefClient client)

This method is called by a CefClient if it was disposed. This causes CefApp to clean up its list of available client instances. If all clients are disposed, CefApp will be shutdown. (如果已处置此方法，则由CefClient调用。这将导致CefApp清理其可用客户端实例的列表。如果处置了所有客户端，则CefApp将关闭。)

参数:

client - the disposed client. (-被处置的客户。)

createClient

public CefClient createClient()

Creates a new client instance and returns it to the caller. One client instance is responsible for one to many browser instances (创建一个新的客户端实例，并将其返回给调用方。一个客户端实例负责一对多的浏览器实例)

返回:

a new client instance (一个新的客户端实例)

dispose

public final void dispose()

To shutdown the system, it's important to call the dispose method. Calling this method closes all client instances with and all browser instances each client owns. After that the message loop is terminated and CEF is shutdown. (要关闭系统，重要的是调用dispose方法。调用此方法将关闭所有客户端实例以及每个客户端拥有的所有浏览器实例。之后，消息循环终止，CEF关闭。)

doMessageLoopWork

public final void doMessageLoopWork(long delay_ms)

Perform a single message loop iteration. Used on all platforms except Windows with windowed rendering. (执行单个消息循环迭代。在带有窗口渲染的Windows之外的所有平台上使用。)

getInstance

public static CefApp getInstance()
                          throws java.lang.UnsatisfiedLinkError

Get an instance of this class. (获取此类的实例。)

返回:

an instance of this class (该类的一个实例)

抛出:

java.lang.UnsatisfiedLinkError

getInstance

public static CefApp getInstance(CefSettings settings)
                          throws java.lang.UnsatisfiedLinkError

抛出:

java.lang.UnsatisfiedLinkError

getInstance

public static CefApp getInstance(java.lang.String[] args)
                          throws java.lang.UnsatisfiedLinkError

抛出:

java.lang.UnsatisfiedLinkError

getInstance

public static CefApp getInstance(java.lang.String[] args,
                                 CefSettings settings)
                          throws java.lang.UnsatisfiedLinkError

抛出:

java.lang.UnsatisfiedLinkError

getState

public static final CefApp.CefAppState getState()

Returns the current state of CefApp. (返回CefApp的当前状态。)

返回:

current state. (当前状态。)

getVersion

public final CefApp.CefVersion getVersion()

handleBeforeTerminate

protected final void handleBeforeTerminate()

This method is invoked by the native code (currently on Mac only) in case of a termination event (e.g. someone pressed CMD+Q). (如果发生终止事件（例如有人按下CMD + Q），则由本地代码（当前仅在Mac上）调用此方法。)

registerSchemeHandlerFactory

public boolean registerSchemeHandlerFactory(java.lang.String schemeName,
                                            java.lang.String domainName,
                                            CefSchemeHandlerFactory factory)

Register a scheme handler factory for the specified |scheme_name| and optional |domain_name|. An empty |domain_name| value for a standard scheme will cause the factory to match all domain names. The |domain_name| value will be ignored for non-standard schemes. If |scheme_name| is a built-in scheme and no handler is returned by |factory| then the built-in scheme handler factory will be called. If |scheme_name| is a custom scheme then also implement the CefApp::OnRegisterCustomSchemes() method in all processes. This function may be called multiple times to change or remove the factory that matches the specified |scheme_name| and optional |domain_name|. Returns false if an error occurs. This function may be called on any thread in the browser process. (为指定的| scheme_name |注册方案处理程序工厂。和可选的| domain_name |。空的| domain |标准方案的值将导致工厂匹配所有域名。 |域名|对于非标准方案，该值将被忽略。如果| scheme_name |是内置方案，| factory |不返回任何处理程序。然后将调用内置的方案处理程序工厂。如果| scheme_name |是一个自定义方案，然后在所有进程中实现CefApp :: OnRegisterCustomSchemes（）方法。可以多次调用此函数以更改或删除与指定的| scheme_name |相匹配的工厂。和可选的| domain_name |。如果发生错误，则返回false。可以在浏览器进程中的任何线程上调用此函数。)

setSettings

public final void setSettings(CefSettings settings)
                       throws java.lang.IllegalStateException

抛出:

java.lang.IllegalStateException

startup

public static final boolean startup()

This method must be called at the beginning of the main() method to perform platform- specific startup initialization. On Linux this initializes Xlib multithreading and on macOS this dynamically loads the CEF framework. (必须在main（）方法的开头调用此方法，以执行特定于平台的启动初始化。在Linux上，这将初始化Xlib多线程，而在macOS上，这将动态加载CEF框架。)
