Constructor Detail

DefaultWindDataset

public DefaultWindDataset()
Constructs a new, empty, dataset. Since there are currently no methods to add data to an existing dataset, you should probably use a different constructor.


DefaultWindDataset

public DefaultWindDataset(java.lang.Object[][][] data)
Constructs a dataset based on the specified data array.

Parameters:
data - the data (null not permitted).
Throws:
java.lang.NullPointerException - if data is null.

DefaultWindDataset

public DefaultWindDataset(java.lang.String[] seriesNames,
                          java.lang.Object[][][] data)
Constructs a dataset based on the specified data array.

Parameters:
seriesNames - the names of the series (null not permitted).
data - the wind data.
Throws:
java.lang.NullPointerException - if seriesNames is null.

DefaultWindDataset

public DefaultWindDataset(java.util.List seriesKeys,
                          java.lang.Object[][][] data)
Constructs a dataset based on the specified data array. The array can contain multiple series, each series can contain multiple items, and each item is as follows:

Parameters:
seriesKeys - the names of the series (null not permitted).
data - the wind dataset (null not permitted).
Throws:
java.lang.IllegalArgumentException - if seriesKeys is null.
java.lang.IllegalArgumentException - if the number of series keys does not match the number of series in the array.
java.lang.NullPointerException - if data is null.
Method Detail

getSeriesCount

public int getSeriesCount()
Returns the number of series in the dataset.

Specified by:
getSeriesCount in interface SeriesDataset
Specified by:
getSeriesCount in class AbstractSeriesDataset
Returns:
The series count.

getItemCount

public int getItemCount(int series)
Returns the number of items in a series.

Specified by:
getItemCount in interface XYDataset
Parameters:
series - the series (zero-based index).
Returns:
The item count.

getSeriesKey

public java.lang.Comparable getSeriesKey(int series)
Returns the key for a series.

Specified by:
getSeriesKey in interface SeriesDataset
Specified by:
getSeriesKey in class AbstractSeriesDataset
Parameters:
series - the series (zero-based index).
Returns:
The series key.

getX

public java.lang.Number getX(int series,
                             int item)
Returns the x-value for one item within a series. This should represent a point in time, encoded as milliseconds in the same way as java.util.Date.

Specified by:
getX in interface XYDataset
Parameters:
series - the series (zero-based index).
item - the item (zero-based index).
Returns:
The x-value for the item within the series.

getY

public java.lang.Number getY(int series,
                             int item)
Returns the y-value for one item within a series. This maps to the getWindForce(int, int) method and is implemented because WindDataset is an extension of XYDataset.

Specified by:
getY in interface XYDataset
Parameters:
series - the series (zero-based index).
item - the item (zero-based index).
Returns:
The y-value for the item within the series.

getWindDirection

public java.lang.Number getWindDirection(int series,
                                         int item)
Returns the wind direction for one item within a series. This is a number between 0 and 12, like the numbers on an upside-down clock face.

Specified by:
getWindDirection in interface WindDataset
Parameters:
series - the series (zero-based index).
item - the item (zero-based index).
Returns:
The wind direction for the item within the series.

getWindForce

public java.lang.Number getWindForce(int series,
                                     int item)
Returns the wind force for one item within a series. This is a number between 0 and 12, as defined by the Beaufort scale.

Specified by:
getWindForce in interface WindDataset
Parameters:
series - the series (zero-based index).
item - the item (zero-based index).
Returns:
The wind force for the item within the series.

seriesNameListFromDataArray

public static java.util.List seriesNameListFromDataArray(java.lang.Object[][] data)
Utility method for automatically generating series names.

Parameters:
data - the wind data (null not permitted).
Returns:
An array of Series N with N = { 1 .. data.length }.
Throws:
java.lang.NullPointerException - if data is null.

equals

public boolean equals(java.lang.Object obj)
Checks this WindDataset for equality with an arbitrary object. This method returns true if and only if:
