Constructor Summary

RipplesDataSetDescriptor()

RipplesDataSetDescriptor(double x1, double y1, double p1, double x2, double y2, double p2, int nx, int ny)
creates a DataSetDescriptor (note the range and resolution is ignored--an unneccessary use since Render now has setDataSet method) that is the sum of two ripples.

creates a DataSetDescriptor (note the range and resolution is ignored--an unneccessary use since Render now has setDataSet method) that is the sum of two ripples.

Parameters:

x1 - the x coordinate of the first ripple source

y1 - the y coordinate of the first ripple source

p1 - the radius of the first ripple

x2 - the x coordinate of the first ripple source

y2 - the y coordinate of the first ripple source

p2 - the radius of the first ripple

nx - the number of columns in the dataset.

ny - the number of rows in the dataset.

Method Detail

getXUnits

public Units getXUnits()

Specified by:

getXUnits in class DataSetDescriptor

Returns:

the x units of the DataSetDescriptor that parameterize the data. This is used to identify dataSet requests.

getYUnits

public Units getYUnits()

getZUnits

public Units getZUnits()

getDataSetImpl

public DataSet getDataSetImpl(Datum start,
                              Datum end,
                              Datum resolution,
                              ProgressMonitor monitor)
                       throws DasException

Description copied from class: DataSetDescriptor

getDataSetImpl implements the getDataSet for this DataSetDescriptor implementation. The getDataSet call of the abstract DataSetDescriptor uses this routine to satisfy requests and fill its cache. This caching may be disabled via setDefaultCaching. To satisfy the request, a DataSet should be returned with an x tag range that contains start and end, with a resolution finer than that requested.

Specified by:

getDataSetImpl in class DataSetDescriptor

Parameters:

start - beginning of range for the request.

end - end of the range for the request.

resolution - the resolution requirement for the reqeust. null may be used to request the finest resolution available or intrinic resolution.

Throws:

DasException
