      • Element

        public Element​(Path path)
        Create a new classpath for the given path.
        Parameters:
        path - the location of the element. May either be a directory or a file.

      • Element

        public Element​(Path path,
               CacheScopeSpecifier cacheScope,
               boolean dynamic,
               OSGIOptions osgiOptions)
        Create a new classpath for the given path.
        Parameters:
        path - the location of the element. May either be a directory or a file.
        cacheScope - specifies where to cache the element
        dynamic - if true, the classpath element will be scanned each time we run a job to see whether its checksum has changed. if false, the checksum will be cached in-memory so that the checksum is only recomputed upon restart.
        osgiOptions - extra options for the case where this is an osgi classpath element. May be null in the case of a non-osgi element

      • cacheScope

        public CacheScopeSpecifier cacheScope()
        Returns the cacheScope of this element. The cache scope controls where the element is cached.

        the cache scope of this element

      • dynamic

        public boolean dynamic()
        Returns whether the classpath element can be dynamically updated at runtime.

        the osgi options scope of this element

      • path

        public ClasspathSpecifier.Element path​(Path path)
        Returns a new ClasspathElement, overriding the path.

        Returns:
        a newly created ClasspathElement

      • cacheScope

        public ClasspathSpecifier.Element cacheScope​(CacheScopeSpecifier cacheScope)
        Returns a new ClasspathElement, overriding the cacheScope.
        Parameters:
        cacheScope - the new cacheScope

        a newly created ClasspathElement

      • dynamic

        public ClasspathSpecifier.Element dynamic​(boolean dynamic)
        Returns a new ClasspathElement, overriding dynamic.
        Parameters:
        dynamic - the new value for dynamic
