Method Details

setClassLoader

public static void setClassLoader(ClassLoader loader)

Sets an explicit class loader for loading EASy-Producer. By default, it's the class loader of the ConfigurationLifecycleDescriptor.

Parameters:

loader - the class loader, ignored if null

instantiate

public static void instantiate(PlatformInstantiator.InstantiationConfigurer configurer)
                        throws ExecutionException

Performs the platform instantiation. Considers the class loader set before through setClassLoader(ClassLoader).

Parameters:

configurer - the configurer

Throws:

ExecutionException - in case that the instantiation fails and the configurer re-throws the exception

main

public static void main(String[] args)
                 throws ExecutionException

Performs the platform instantiation.

Parameters:

args - command line arguments

Throws:

ExecutionException - in case that the VIL instantiation fails, shall not occur here as handled by default PlatformInstantiator.InstantiationConfigurer

setTraceFilter

public static void setTraceFilter()

Sets the trace filter based on the system property KEY_PROPERTY_TRACING.

mainImpl

public static int mainImpl(String[] args)
                    throws ExecutionException

Main functionality without returning exit code/output of help for re-use. Could be with explicit parameters...

Parameters:

args - command line arguments

Returns:

the exit code

Throws:

ExecutionException - in case that the VIL instantiation fails, shall not occur here as handled by default PlatformInstantiator.InstantiationConfigurer
