方法详细资料

addAppHandler

public static void addAppHandler(CefAppHandler appHandler)
                          throws 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.

参数:

appHandler - An instance of CefAppHandler.

抛出:

IllegalStateException - in case of CefApp is already initialized

getInstance

public static CefApp getInstance()
                          throws UnsatisfiedLinkError

Get an instance of this class.

返回:

an instance of this class

抛出:

UnsatisfiedLinkError

getInstance

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

抛出:

UnsatisfiedLinkError

getInstance

public static CefApp getInstance(CefSettings settings)
                          throws UnsatisfiedLinkError

抛出:

UnsatisfiedLinkError

getInstance

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

抛出:

UnsatisfiedLinkError

setSettings

public final void setSettings(CefSettings settings)
                       throws IllegalStateException

抛出:

IllegalStateException

getVersion

public final CefApp.CefVersion getVersion()

getState

public static final CefApp.CefAppState getState()

Returns the current state of CefApp.

返回:

current state.

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.

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

返回:

a new client instance

registerSchemeHandlerFactory

public boolean registerSchemeHandlerFactory(String schemeName,
                                   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.

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.

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.

参数:

client - the disposed client.

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). The native termination process is interrupted until CefApp calls continueTerminate().
