List of all members.

Public Member Functions
override TimeZoneResult	FindResult (float latDeg, float lonDeg)
	Returns a results map query result. All result classes extend ResultBase but the specific subclass returned depends on what map class is being used. Each map class has a companion result class. If no shape is found at or near the query point, null is returned.
override String	GetOracleName ()
	A unique identifier for this map, used in the license file and in the AskGeo Web API.
Public Member Functions inherited from AskGeo.Flt.GeneralMap< ResultType >
List< ResultType >	GetAllResults ()
	Returns a Vector of results, each result corresponding to a shape in the map. All result classes extend ResultBase but the specific subclass depends on what map class is being used. Each map class has a companion result class.
void	Authorize (String s)
	Authorizes the use of the map object by providing a license String.
void	Authorize (Stream stream)
	Authorizes the use of the map object by providing a license file's input stream. The stream is closed upon completion.
float[]	GetBbox ()
	Returns the bounding box for this map as a float array. The order of the array is: min latitude, min longitude, max latitude, max longitude.
DataFieldInterface	GetDataField (int index)
	Each map contains metadata associated with each shape. The metadata is indexed by an Java-style enum that is defined within each map subclass. All of the Java-style enums implement the DataFieldInterface. Those Java-style enums are exposed through this common interface here.
int	GetNumDataFields ()
	Returns the number of data fields associated with this map.

Static Public Member Functions
static TimeZoneMap	Create (Stream dataFileStream)
	Static factory method used to construct an instance of this class.
static TimeZoneMap	Create (Stream dataFileStream, float cellsPerDeg, float snapRadiusKm)
	Static factor method used to construct an instance of this class.
static String	GetOracleNameStatic ()
	A unique identifier for this map, used in the license file and in the AskGeo Web API.
Static Public Member Functions inherited from AskGeo.Flt.GeneralMap< ResultType >
static float[]	GetWorldBbox ()
	Returns a new bounding box encompassing the entire globe (for example, from -180 to +180 degrees longitude and from -90 to +90 degrees latitude). Values are stored in radians.
static float[]	GetConusBbox ()
	Returns a new bounding box roughly containing the continental US, or CONUS (i.e., from -125 to -66 degrees longitude and from 24 to 50 degrees latitude).

static TimeZoneMap AskGeo.Flt.TimeZoneMap.Create ( Stream  dataFileStream )

static

Static factory method used to construct an instance of this class.

Parameters:

dataFileStream

a Stream of the datafield to be read to create this map.

Returns:

an instance of this class with default parameters.

static TimeZoneMap AskGeo.Flt.TimeZoneMap.Create ( Stream  dataFileStream, float  cellsPerDeg, float  snapRadiusKm  )

static

Static factor method used to construct an instance of this class.

Parameters:

dataFileStream	a Stream of the data file to be read to create this map.
cellsPerDeg	the resolution of the spatial index. Testing has show that a suitable value for this parameter is 1.0, which is the default value.
snapRadiusKm	the maximum snap-to distance for query points not inside any shape on the map.

Returns:

an instance of this class with given parameters.

override TimeZoneResult AskGeo.Flt.TimeZoneMap.FindResult ( float  latDeg, float  lonDeg  )

virtual

Returns a results map query result. All result classes extend ResultBase but the specific subclass returned depends on what map class is being used. Each map class has a companion result class. If no shape is found at or near the query point, null is returned.

Parameters:

latDeg	the latitude of the query point, expressed in degrees.
lonDeg	the longitude of the query point, expressed in degrees.

Returns:

the result for the given latitude and longitude, or null if none is found.

Implements AskGeo.Flt.GeneralMap< ResultType >.

override String AskGeo.Flt.TimeZoneMap.GetOracleName ( )

virtual

A unique identifier for this map, used in the license file and in the AskGeo Web API.

Returns:

the unique identifier for this map.

Implements AskGeo.Flt.GeneralMap< ResultType >.

static String AskGeo.Flt.TimeZoneMap.GetOracleNameStatic ( )

static

A unique identifier for this map, used in the license file and in the AskGeo Web API.

Returns:

the unique identifier for this map.
