extends Object

implements MapperInterface

Constructor Summary

Mapper()
Default constructor, used for testing.

Mapper(DataStoreConnection dataStore)
Constructor for creating a connection to a database.

Mapper(GPS upper, GPS lower, ArrayList polygonlist)
Another constructor for testing

Method Summary

GPS	address2gps(String convaddress) Convert address to GPS coordinate by calling HornerHash() and then hash2GPS() Conversion is repeatable for any given address.
int	address2zone(String convaddress) Convert address to zone, via two function calls
ArrayList	createzonelist() For unit testing only.
ArrayList	getNeighboringZones(int zoneID) Return a list of neighboring zone indices for a given zone index
int	getNumZones() Return the number of zones.
ArrayList	getZones() Return an address.
int	gps2zone(GPS g) Convert GPS to zone, if the GPS coordinate is not in any zone, will return nearest zone.

              ArrayList polygonlist)

Another constructor for testing

Method Detail

address2gps

public GPS address2gps(String convaddress)

Convert address to GPS coordinate by calling HornerHash() and then hash2GPS() Conversion is repeatable for any given address. GPS coordinate generated is within the rectangle bounded by upperGPSlim and lowerGPSlim

Specified by:

address2gps in interface MapperInterface

Parameters:

address - to be converted

Returns:

gps coordinate

address2zone

public int address2zone(String convaddress)

Convert address to zone, via two function calls

Specified by:

address2zone in interface MapperInterface

Parameters:

String - - Address to be converted

Returns:

int - Zone id

gps2zone

public int gps2zone(GPS g)

Convert GPS to zone, if the GPS coordinate is not in any zone, will return nearest zone.

Specified by:

gps2zone in interface MapperInterface

Parameters:

GPS - to be converted

Returns:

zone

getZones

public ArrayList getZones()

Return an address.

Specified by:

getZones in interface MapperInterface

Returns:

A list of the zones

getNumZones

public int getNumZones()

Return the number of zones.

Specified by:

getNumZones in interface MapperInterface

Returns:

int Number of zones

getNeighboringZones

public ArrayList getNeighboringZones(int zoneID)

Return a list of neighboring zone indices for a given zone index

Specified by:

getNeighboringZones in interface MapperInterface

Parameters:

int - zoneID

Returns:

ArrayList a list of neighboring zone IDs

createzonelist

public ArrayList createzonelist()

For unit testing only. To create two equal area zones for testing. Bounding rectangle is (10, 10) and (-10, -10). The zones are split along the x axis.

Returns:

zonelist with two rectangular zones
