Method Detail

inside

public static P<Object> inside(Point center,
                               double radius,
                               Geo.Unit units)

Graph predicate to find whether an entity is inside a defined area using a geo coordinate system.

Parameters:

center - the center of the area to look into.

radius - the radius of the area to look into.

units - the units of the radius.

Returns:

a predicate to use in TinkerPop on a graph data set.

inside
