public StandardXYURLGenerator() 
{
                         
        this(DEFAULT_PREFIX, DEFAULT_SERIES_PARAMETER, DEFAULT_ITEM_PARAMETER);
}

Creates a new default generator. This constructor is equivalent to calling StandardXYURLGenerator("index.html", "series", "item"); .

 public StandardXYURLGenerator(String prefix) 
{
        this(prefix, DEFAULT_SERIES_PARAMETER, DEFAULT_ITEM_PARAMETER);
}

Creates a new generator with the specified prefix. This constructor is equivalent to calling StandardXYURLGenerator(prefix, "series", "item");.

Parameters:

prefix - the prefix to the URL (null not permitted).

 public StandardXYURLGenerator(String prefix,
    String seriesParameterName,
    String itemParameterName) 
{
        if (prefix == null) {
            throw new IllegalArgumentException("Null 'prefix' argument.");
        }
        if (seriesParameterName == null) {
            throw new IllegalArgumentException(
                    "Null 'seriesParameterName' argument.");
        }
        if (itemParameterName == null) {
            throw new IllegalArgumentException(
                    "Null 'itemParameterName' argument.");
        }
        this.prefix = prefix;
        this.seriesParameterName = seriesParameterName;
        this.itemParameterName = itemParameterName;
}

Constructor that overrides all the defaults

Parameters:

prefix - the prefix to the URL (null not permitted).

seriesParameterName - the name of the series parameter to go in each URL (null not permitted).

itemParameterName - the name of the item parameter to go in each URL (null not permitted).

            return false;
        }
        return true;
}

Tests this generator for equality with an arbitrary object.

 public String generateURL(XYDataset dataset,
    int series,
    int item) 
{
        String url = this.prefix;
        boolean firstParameter = url.indexOf("?") == -1;
        url += firstParameter ? "?" : "&";
        url += this.seriesParameterName + "=" + series
                + "&" + this.itemParameterName + "=" + item;
        return url;
}

Generates a URL for a particular item within a series.
