Overview

This RFC is for adding spatial operator combinations support.

Motivation

Allows implementation of the RELATE spatial filter.

[TODO]

Proposed Solution

A number of changes in FDO are proposed:

1) Add new FdoSpatialOperations_Relate to FdoSpatialOperations enumeration

2) Assign values to FdoSpatialOperations so they can be bitmapped:

enum FdoSpatialOperations {

FdoSpatialOperations_EnvelopeIntersects = 0x0000, FdoSpatialOperations_Relate = 0x0001, FdoSpatialOperations_Contains = 0x0002, FdoSpatialOperations_Crosses = 0x0004, FdoSpatialOperations_Disjoint = 0x0008, FdoSpatialOperations_Equals = 0x0010, FdoSpatialOperations_Intersects = 0x0020, FdoSpatialOperations_Overlaps = 0x0040, FdoSpatialOperations_Touches = 0x0080, FdoSpatialOperations_Within = 0x0100, FdoSpatialOperations_CoveredBy = 0x0200, FdoSpatialOperations_Inside = 0x0400

};
