Method Detail

getMetersConversionFactor

protected static double getMetersConversionFactor(java.lang.String unitsString)
                                           throws java.lang.Exception

Get conversion factor for this unit into meters.

Parameters:

unitsString - unit you want to convert

Returns:

conversion factor : value in meters = factor * (value in units)

Throws:

java.lang.Exception - if not valid unit, or not convertible to meters

setTimeUnits

protected abstract void setTimeUnits()

getDetailInfo

public java.lang.String getDetailInfo()

Description copied from interface: TypedDataset

Show debug / underlying implementation details

Specified by:

getDetailInfo in interface TypedDataset

Overrides:

getDetailInfo in class TypedDatasetImpl

getScientificDataType

public DataType getScientificDataType()

getDataClass

public java.lang.Class getDataClass()

Description copied from interface: PointCollection

The getData() methods return objects of this Class

Specified by:

getDataClass in interface PointCollection

getTimeUnits

public DateUnit getTimeUnits()

Description copied from interface: PointCollection

Get the units of Calendar time. To get a Date, from a time value, call DateUnit.makeDate(double value). To get units as a String, call DateUnit.getUnitsString().

Specified by:

getTimeUnits in interface PointCollection

getData

public java.util.List getData()
                       throws java.io.IOException

Description copied from interface: PointCollection

Get all data. Return null if too expensive to implement. Call getDataCount() to get estimate of size. This will return a list of getDataClass(), but the actual data may or may not already be read in to memory. In any case, you call dataType.getData() to get the data.

Specified by:

getData in interface PointCollection

Returns:

List of type getDataClass()

Throws:

java.io.IOException

See Also:

as a (possibly) more efficient alternative

getData

public java.util.List getData(LatLonRect boundingBox)
                       throws java.io.IOException

Description copied from interface: PointCollection

Get all data within the specified bounding box.

Specified by:

getData in interface PointCollection

Returns:

List of type getDataClass()

Throws:

java.io.IOException

See Also:

as a (possibly) more efficient alternative

getData

public java.util.List getData(LatLonRect boundingBox,
                              java.util.Date start,
                              java.util.Date end)
                       throws java.io.IOException

Description copied from interface: PointCollection

Get all data within the specified bounding box and date range.

Specified by:

getData in interface PointCollection

Returns:

List of type getDataClass()

Throws:

java.io.IOException

getTime

protected double getTime(Variable timeVar,
                         StructureData sdata)
                  throws java.text.ParseException

Throws:

java.text.ParseException
