  • All Implemented Interfaces:

    public class WindBarbsFactory
    extends Object
    implements MarkFactory
    Factory to produce WindBarbs. Urls for wind barbs are in the form: windbarbs://default(speed_value)[units_of_measure]

    TODO: We may consider adding a FLAG to say whether the arrows are toward wind (meteo convention) or against wind (ocean convention)

        Specified by:
        getShape in interface MarkFactory
        symbolUrl - the expression that will return the symbol name. Once evaluated the expression should return something like plainName or like protocol://path. See the actual implementations for details on the kind of supported name.
        feature - The feature that will be used to evaluate the symbolURL expression (or to extract data from it, think complex attributes, in that case a visit to the expression and some direct attribute value extraction might be needed instead)
