Constructor Detail

GeoavailabilityMap

public GeoavailabilityMap(java.lang.String baseGeohash,
                          int precision)

Method Detail

addPoint

public boolean addPoint(Coordinates coords,
                        T data)

Adds a new point to this GeoavailabilityMap, and associates it with a data point.

Parameters:

coords - The location (coordinates in lat, lon) to add.

data - Data point to associate with the location.

Returns:

true if the point could be added to map, false otherwise (for example, if the point falls outside the purview of the grid)

indexToSpatialRange

public SpatialRange indexToSpatialRange(int index)

Retrieves the SpatialRange represented by a grid index point.

query

public java.util.Map<java.lang.Integer,java.util.List<T>> query(GeoavailabilityQuery query)
                                                         throws BitmapException

Queries the GeoavailabilityGrid, returning the grid indices that contain matching points, with lists of their associated data points.

Parameters:

query - GeoavailabilityQuery to evaluate

Returns:

results, as a Map of indices to arrays of data points.

Throws:

BitmapException
