        public boolean hasResource​(java.lang.String path)
        Description copied from interface: ResourceLoader
        Checks whether this loader can load resource identified by path.
        Specified by:
        hasResource in interface ResourceLoader
        Parameters:
        path - the path identifying resource.
        Returns:
        true whether this loader can load resource, otherwise false.

        protected boolean isResourceExisting​(java.lang.String path)
        Checks whether a resource identified by path exist.
        Parameters:
        path - the path identifying resource.
        Returns:

        Throws:
        java.lang.IllegalArgumentException - if the path is blank.

      • getResourceByPath

        protected java.io.InputStream getResourceByPath​(java.lang.String path)
        Returns resource identified by path as InputStream or null if resource does not exist.
        Parameters:
        path - the path identifying resource.
        Returns:
        the input stream or null if the resource does not exist.
