Method Detail

initialize

public static void initialize()

Initializes Chromium engine. Depending on the environment this method behaves differently.

Windows and Linux (Swing & JavaFX): Chromium engine is initialized automatically when a first Browser instance is created. When last Browser instance is disposed, Chromium engine is uninitialized. Chromium engine is initialized and running is separate native process.

Mac (Swing): Chromium engine is initialized automatically when a first Browser instance is created. Chromium engine is initialized in Java process and it will not be uninitialized when last Browser instance is disposed.

Mac (JavaFX): Chromium engine must be initialized manually using this method in any non-UI thread. If you initialize Chromium engine in UI-thread such as "JavaFX Application Thread", you will get a deadlock. Chromium engine is initialized in Java process and it will not be uninitialized when last Browser instance is disposed.

初始化Chromium引擎。根据环境的不同，此方法的行为也有所不同。 Windows和Linux（Swing和JavaFX）：创建第一个Browser实例时，Chromium引擎会自动初始化。放置最后一个Browser实例时，Chromium引擎未初始化。 Chromium引擎已初始化，运行是单独的本机进程。 Mac（Swing）：创建第一个Browser实例时，Chromium引擎会自动初始化。 Chromium引擎在Java进程中已初始化，并且在处置最后一个Browser实例时不会将其未初始化。 Mac（JavaFX）：必须在任何非UI线程中使用此方法手动初始化Chromium引擎。如果在UI线程（例如“ JavaFX Application Thread”）中初始化Chromium引擎，则会出现死锁。 Chromium引擎在Java进程中已初始化，并且在处置最后一个Browser实例时不会将其未初始化。

Throws:

java.lang.IllegalStateException - when this method is invoked in "JavaFX Application Thread" on Mac OS X.

isInitialized

public static boolean isInitialized()

Checks whether Chromium engine is initialized.

检查Chromium引擎是否已初始化。

Returns:

true when Chromium engine is initialized. 当Chromium引擎初始化时。

shutdown

public static void shutdown()

Shutdowns Chromium engine. Depending on the environment this method behaves differently.

Windows and Linux (Swing & JavaFX): this method does nothing. Chromium engine is disposed automatically when the last Browser instance is disposed.

Mac (Swing & JavaFX): Chromium engine must be disposed manually after all Browser instances are disposed. This method is invoked asynchronously. Once you shutdown Chromium engine, you cannot use it anymore. Invoke this method only when Java application exit.

关闭铬引擎。根据环境的不同，此方法的行为也有所不同。 Windows和Linux（Swing和JavaFX）：此方法无效。在处理最后一个Browser实例时，会自动处理Chromium引擎。 Mac（Swing＆JavaFX）：处置所有浏览器实例后，必须手动处置Chromium引擎。该方法是异步调用的。关闭Chromium引擎后，您将无法再使用它。仅当Java应用程序退出时才调用此方法。

Throws:

com.teamdev.jxbrowser.chromium.internal.ipc.IPCException - when there are one or more alive Browser instances.
