Class Rythm

java.lang.Object

org.rythmengine.Rythm

public class Rythm
extends Object

Rythm is a service wrapper of the RythmEngine.

For most cases you can play with Rythm instead of an individual RythmEngine instance

Since Rythm is a wrapper class, all services are provided via static methods and delegated to an internal RythmEngine instance, which as I called, the default engine

Method Detail

init

public static void init(Map<String,?> conf)

Initialize default engine instance with specified configuration

Note this method can not be called more than once during a JVM lifecycle. if the default engine instance is created already then an IllegalStateException will be thrown out

When the default engine’s shutdown method get called the default engine instance will be discard. Calling any servicing method of Rythm will cause an new RythmEngine initialized as the new default engine

Parameters:

conf - the configurations

getShutdownService

public static org.rythmengine.ShutdownService getShutdownService(boolean isGaeAvailable)

init

public static void init(File file)

Initialize default engine instance with specified configuration file

Note this method can not be called more than once during a JVM lifecycle. if the default engine instance is created already then an IllegalStateException will be thrown out

When the default engine’s shutdown method get called the default engine instance will be discard. Calling any servicing method of Rythm will cause an new RythmEngine initialized as the new default engine

Parameters:

file - the configuration file

init

public static void init()

Initialize default engine instance with default configuration.

Just like init(java.util.Map) method, this method cannot be called more than once

Note this default engine instance will be implicitly initialized with the default configuration if render or the lazy load engine() methods are called before calling any init methods

init

public static void init(RythmEngine engine)

Use an pre-initialized engine as the default engine. Note if there are already default engine initialized then the method will raise a IllegalStateException

When the default engine’s shutdown method get called the default engine instance will be discard. Calling any servicing method of Rythm will cause an new RythmEngine initialized as the new default engine

Parameters:

engine -

engine

public static RythmEngine engine()

Return the default engine. If the default engine is not initialized yet, then initialize it and then return

Returns:

default engine

insideSandbox

public static boolean insideSandbox()

Returns:

true if the current thread is in sandbox mode

See Also:

RythmEngine.insideSandbox()

sandbox

public static Sandbox sandbox()

Returns:

an new sandbox

See Also:

RythmEngine.sandbox()

sandbox

public static Sandbox sandbox(Map<String,Object> userContext)

Parameters:

userContext -

Returns:

an new sandbox with user context specified

See Also:

RythmEngine.sandbox(java.util.Map)

isProdMode

public boolean isProdMode()

Check if default engine is running in production mode

Returns:

true if default engine is in prod mode

prepare

                                 Map<String,Object> usrCtx)

Prepare the render operation environment settings

Parameters:
