All Implemented Interfaces:

Closeable, AutoCloseable

public class FunctionPackageManager
extends Object
implements Closeable

This class is responsible for the handling of FunctionPackage It is responsible for the import of FunctionPackage. The import of a FunctionPackage means:

• the persistence of the FunctionPackage itself
• the definition of the Function contained in the package
• the registration of change watcher of the package file of the FunctionPackage
