• GWT

  public GWT()

Method Detail

• create

  public static <T> T create(java.lang.Class<?> classLiteral)

  Instantiates a class via deferred binding.

  The argument to create(Class) must be a class literal because the Production Mode compiler must be able to statically determine the requested type at compile-time. This can be tricky because using a Class variable may appear to work correctly in Development Mode.

  Parameters:

  classLiteral - a class literal specifying the base class to be instantiated

  Returns:

  the new instance, which must be cast to the requested class

• getUniqueThreadId

  public static java.lang.String getUniqueThreadId()

  Returns the empty string when running in Production Mode, but returns a unique string for each thread in Development Mode (for example, different windows accessing the dev mode server will each have a unique id, and hitting refresh without restarting dev mode will result in a new unique id for a particular window. TODO(unnurg): Remove this function once Dev Mode rewriting classes are in gwt-dev.

• getVersion

  public static java.lang.String getVersion()

  Get a human-readable representation of the GWT version used, or null if this is running on the client.

  Returns:

  a human-readable version number, such as "2.5"

• isClient

  public static boolean isClient()

  Returns true when running inside the normal GWT environment, either in Development Mode or Production Mode. Returns false if this code is running in a plain JVM. This might happen when running shared code on the server, or during the bootstrap sequence of a GWTTestCase test.

• isProdMode

  public static boolean isProdMode()

  Returns true when running in production mode. Returns false when running either in development mode, or when running in a plain JVM.

• isScript

  public static boolean isScript()

  Determines whether or not the running program is script or bytecode.

• log

  public static void log(java.lang.String message)

  Logs a message to the development shell logger in Development Mode, or to the JavaScript console in Super Dev Mode. Calls are optimized out in Production Mode.

• log

  public static void log(java.lang.String message,
         java.lang.Throwable e)

  Logs a message to the development shell logger in Development Mode, or to the JavaScript console in Super Dev Mode. Calls are optimized out in Production Mode.

• debugger

  public static void debugger()

  Emits a JavaScript "debugger" statement on the line that called this method. If the user has the browser's debugger open, the debugger will stop when the GWT application executes that line. There is no effect in Dev Mode or in server-side code.

• setBridge

  public static void setBridge(GWTBridge bridge)

  Called via reflection in Development Mode; do not ever call this method in Production Mode. May be called in server code to initialize server bridge.
