Method Detail

checkAndLimitMaximumLatitude

public static Double checkAndLimitMaximumLatitude(Double value)

force the latitude to a minimum

Parameters:

value -

Returns:

checkAndLimitMaximumLongitude

public static Double checkAndLimitMaximumLongitude(Double value)

force the longitude to a minimum

Parameters:

value -

Returns:

findNearParameterIndex

public static int findNearParameterIndex(List<QueryParameter> searchParameters)

Finds the index of the 'near' parameter in the passed list of search parameters. If not found, -1 is returned.

Parameters:

searchParameters -

Returns:

int - The index of the 'near' parameter in the passed List.

isLocation

public static boolean isLocation(Class<?> resourceType,
                                 QueryParameter queryParm)

Check if it's a location and 'near'

Parameters:

resourceType -

queryParm -

Returns:

checkNull

public static boolean checkNull(Double val)

if null, return true.

Parameters:

val -

Returns:

checkLatValid

public static boolean checkLatValid(Double lat)

common constraint for valid latitude and longitude.

Parameters:

lat -

Returns:

checkLonValid

public static boolean checkLonValid(Double lon)

common constraint for valid latitude and longitude.

Parameters:

lon -

Returns:

checkOverUnderNinety

public static void checkOverUnderNinety(Double up,
                                        Double down)
                                 throws FHIRSearchException

check if the location/area spans over the pole (either one). If it does, just frankly, it's hard to do the math properly.

Parameters:

up -

down -

Throws:

FHIRSearchException
