Method Detail

init

public static void init()

Initializes all dmn engines that can be found on the classpath for resources activiti.dmn.cfg.xml and for resources activiti-dmn-context.xml (Spring style configuration).

registerDmnEngine

public static void registerDmnEngine(DmnEngine dmnEngine)

Registers the given dmn engine. No DmnEngineInfo will be available for this dmn engine. An engine that is registered will be closed when the destroy() is called.

unregister

public static void unregister(DmnEngine dmnEngine)

Unregisters the given dmn engine.

buildDmnEngine

protected static DmnEngine buildDmnEngine(URL resource)

getDmnEngineInfos

public static List<DmnEngineInfo> getDmnEngineInfos()

Get initialization results.

getDmnEngineInfo

public static DmnEngineInfo getDmnEngineInfo(String dmnEngineName)

Get initialization results. Only info will we available for dmn engines which were added in the init(). No DmnEngineInfo is available for engines which were registered programmatically.

getDefaultDmnEngine

public static DmnEngine getDefaultDmnEngine()

getDmnEngine

public static DmnEngine getDmnEngine(String dmnEngineName)

obtain a dmn engine by name.

Parameters:

dmnEngineName - is the name of the dmn engine or null for the default dmn engine.

retry

public static DmnEngineInfo retry(String resourceUrl)

retries to initialize a dmn engine that previously failed.

getDmnEngines

public static Map<String,DmnEngine> getDmnEngines()

provides access to dmn engine to application clients in a managed server environment.

destroy

public static void destroy()

closes all dmn engines. This method should be called when the server shuts down.

isInitialized

public static boolean isInitialized()

setInitialized

public static void setInitialized(boolean isInitialized)
