                                 java.lang.Object value)
        Description copied from interface: AVList
        Adds a key/value pair to the list. Replaces an existing key/value pair if the list already contains the key.
        Specified by:
        setValue in interface AVList
        Overrides:
        setValue in class AVListImpl
        Parameters:
        key - the attribute name. May not be null.
        value - the attribute value. May be null, in which case any existing value for the key is removed from the collection.
        Returns:
        previous value associated with specified key, or null if there was no mapping for key. A null return can also indicate that the map previously associated null with the specified key, if the implementation supports null values.

      • getValue

        public java.lang.Object getValue​(java.lang.String key)
        Description copied from interface: AVList

        Specified by:
        getValue in interface AVList
        Overrides:
        getValue in class AVListImpl
        Parameters:
        key - the attribute name. May not be null.
        Returns:
        the attribute value if one exists in the collection, otherwise null.

      • getTileResourceURL

                                throws java.net.MalformedURLException
        Returns the URL necessary to retrieve the specified tile.
        Parameters:
        tile - the tile who's resources will be retrieved.
        imageFormat - a string identifying the mime type of the desired image format
        Returns:
        the resource URL.
        Throws:
        java.net.MalformedURLException - if the URL cannot be formed from the tile's parameters.
        java.lang.IllegalArgumentException - if tile is null.
