Constructor Detail

ClassLoaderService

public ClassLoaderService(NiMKernelServiceVisa visa)

The constructor of ClassLoaderService. All implementation must have a constructor that takes a NiMKernelServiceVisa and call this constructor with "super( visa )".

Parameters:

visa - Reference to the NiMKernelServiceVisa object required to instantiate the service. This parameter is required to ensure that only the NiMkernel can instantiate a reference to this service.

Method Detail

init

protected abstract void init(NiMKernel kernel,
                             ConfigurationService confService)
                      throws InitializationFailedException,
                             NiMException

Description copied from class: NiMKernelService

This method is used to initialize the kernel service. Extenders of this class must implement this method.

Specified by:

init in class NiMKernelService

Parameters:

kernel - Reference to the NiMKernel object that instantiated the service.

confService - A reference to the configuration service. All the service implementations (except ConfigurationService) should retrieve the setting information from it.

Throws:

InitializationFailedException - If unable to initialize the kernel service.

NiMException - If service initialization can not be done due to failure in establish a connection to the back-end service. Not all service implementation will throw this exception.

getClassLoader

public abstract java.lang.ClassLoader getClassLoader()

This method returns the NiM class loader used to load classes.

Returns:

The class loader used by NiM to load its classes.

getSystemClassLoader

public abstract java.lang.ClassLoader getSystemClassLoader()

This method returns the class loader that loaded the NiMKernel instance.

Returns:

Reference to the class loader that loaded the NiMKernel instance
