Arguments

repository

Object of type repository specifying server details and repository to work on.

stripWidth

Determines the granularity of the strip.

xMin

Helps determine size of cartesian plane

xMax

Helps determine size of cartesian plane

yMin

Helps determine size of cartesian plane

yMax

Helps determine size of cartesian plane

unit

Defaults to 'degree'. The unit in which stripWidth is specified. It can be degree, km, radian or mile.

latMin

Limit the size of the region modelled by appropriate type

latMax

Limit the size of the region modelled by appropriate type

longMin

Limit the size of the region modelled by appropriate type

longMax

Limit the size of the region modelled by appropriate type

type

Specifies a geospatial sub-type, as created by getCartesianGeoType or getSphericalGeoType

predicate

Specifies a predicate for the query

limit

Specifies a maximum number of triples to return

x

Specifies x-coordinate of circle

y

Specifies y-coordinate of circle

radius

Specifies the radius of the circle

offset

Specifies how many triples should be skipped over

lat

Specifies the latitude of the center of the circle

long

Specifies the longitude of the center of the circle

radiusUnit

Defaults to km. Spefies the unit in which radius is given when using Haversine

resource

Name of the polygon to add

points

A list of points represented as AllegroGraph geospatial object (created through createCartesianGeoLiteral)

useContext

When true (default false), use the context (graph) field of the triple instead of its object
