LatLngToECEFFilter

public LatLngToECEFFilter(EarthModel model)

Constructor.

Parameters:

model - Earth model

Method Detail

filterSingleObject

protected V filterSingleObject(V obj)

Description copied from class: AbstractStreamConversionFilter

Normalize a single instance. You can implement this as UnsupportedOperationException if you override both public "normalize" functions!

Specified by:

filterSingleObject in class AbstractStreamConversionFilter<V extends NumberVector,V extends NumberVector>

Parameters:

obj - Database object to normalize

Returns:

Normalized database object

getInputTypeRestriction

protected SimpleTypeInformation<? super V> getInputTypeRestriction()

Description copied from class: AbstractStreamConversionFilter

Get the input type restriction used for negotiating the data query.

Specified by:

getInputTypeRestriction in class AbstractStreamConversionFilter<V extends NumberVector,V extends NumberVector>

Returns:

Type restriction

convertedType

protected SimpleTypeInformation<? super V> convertedType(SimpleTypeInformation<V> in)

Description copied from class: AbstractStreamConversionFilter

Get the output type from the input type after conversion.

Specified by:

convertedType in class AbstractStreamConversionFilter<V extends NumberVector,V extends NumberVector>

Parameters:

in - input type restriction

Returns:

output type restriction
