static int PrepGeomCacheBuilder (const LWGEOM *lwgeom, GeomCache *cache)
 Given a generic GeomCache, and a geometry to prepare, prepare a PrepGeomCache and stick it into the GeomCache->index slot. More...
 
static int PrepGeomCacheCleaner (GeomCache *cache)
 This function is passed into the generic GetGeomCache function in the case of a cache miss, so that it can free the particular indexed structure being managed. More...

PrepGeomCacheGetPrepGeomCache (FunctionCallInfoData *fcinfo, GSERIALIZED *g1, GSERIALIZED *g2)
 Given a couple potential geometries and a function call context, return a prepared structure for one of them, if such a structure doesn't already exist. More...
