Functions | |
| lwflags_t | gserialized_get_lwflags (const GSERIALIZED *g) |
| Read the flags from a GSERIALIZED and return a standard lwflag integer. More... | |
| GSERIALIZED * | gserialized_set_gbox (GSERIALIZED *g, GBOX *gbox) |
| Copy a new bounding box into an existing gserialized. More... | |
| uint32_t | gserialized_get_version (const GSERIALIZED *g) |
| Return the serialization version. More... | |
| GSERIALIZED * | gserialized_drop_gbox (GSERIALIZED *g) |
| Remove the bounding box from a GSERIALIZED. More... | |
| int | gserialized_get_gbox_p (const GSERIALIZED *g, GBOX *gbox) |
| Read the box from the GSERIALIZED or calculate it if necessary. More... | |
| int | gserialized_fast_gbox_p (const GSERIALIZED *g, GBOX *gbox) |
| Read the box from the GSERIALIZED or return #LWFAILURE if box is unavailable. More... | |
| uint32_t | gserialized_get_type (const GSERIALIZED *g) |
| Extract the geometry type from the serialized form (it hides in the anonymous data area, so this is a handy function). More... | |
| uint32_t | gserialized_max_header_size (void) |
| Returns the size in bytes to read from toast to get the basic information from a geometry: GSERIALIZED struct, bbox and type. More... | |
| int32_t | gserialized_hash (const GSERIALIZED *g) |
| Returns a hash code for the srid/type/geometry information in the GSERIALIZED. More... | |
| int32_t | gserialized_get_srid (const GSERIALIZED *g) |
| Extract the SRID from the serialized form (it is packed into three bytes so this is a handy function). More... | |
| void | gserialized_set_srid (GSERIALIZED *g, int32_t srid) |
| Write the SRID into the serialized form (it is packed into three bytes so this is a handy function). More... | |
| int | gserialized_is_empty (const GSERIALIZED *g) |
| Check if a GSERIALIZED is empty without deserializing first. More... | |
| int | gserialized_has_bbox (const GSERIALIZED *g) |
| Check if a GSERIALIZED has a bounding box without deserializing first. More... | |
| int | gserialized_has_z (const GSERIALIZED *g) |
| Check if a GSERIALIZED has a Z ordinate. More... | |
| int | gserialized_has_m (const GSERIALIZED *g) |
| Check if a GSERIALIZED has an M ordinate. More... | |
| int | gserialized_is_geodetic (const GSERIALIZED *g) |
| Check if a GSERIALIZED is a geography. More... | |
| int | gserialized_ndims (const GSERIALIZED *g) |
| Return the number of dimensions (2, 3, 4) in a geometry. More... | |
| GSERIALIZED * | gserialized_from_lwgeom (LWGEOM *geom, size_t *size) |
| Allocate a new GSERIALIZED from an LWGEOM. More... | |
| size_t | gserialized_from_lwgeom_size (const LWGEOM *geom) |
| Return the memory size a GSERIALIZED will occupy for a given LWGEOM. More... | |
| LWGEOM * | lwgeom_from_gserialized (const GSERIALIZED *g) |
| Allocate a new LWGEOM from a GSERIALIZED. More... | |
| const float * | gserialized_get_float_box_p (const GSERIALIZED *g, size_t *ndims) |
| Access to the float bounding box, if there is one. More... | |
| int | gserialized_peek_first_point (const GSERIALIZED *g, POINT4D *out_point) |
| Pull the first point values of a GSERIALIZED. More... | |
| static size_t | gserialized_header_size (const GSERIALIZED *g) |
| static int | gserialized_cmp_srid (const GSERIALIZED *g1, const GSERIALIZED *g2) |
| int | gserialized_cmp (const GSERIALIZED *g1, const GSERIALIZED *g2) |
| Return -1 if g1 is "less than" g2, 1 if g1 is "greater than" g2 and 0 if g1 and g2 are the "same". More... | |
| uint64_t | gserialized_get_sortable_hash (const GSERIALIZED *g) |
| Return a sortable key based on gserialized. More... | |
| void | gserialized_error_if_srid_mismatch (const GSERIALIZED *g1, const GSERIALIZED *g2, const char *funcname) |
| void | gserialized_error_if_srid_mismatch_reference (const GSERIALIZED *g1, const int32_t srid2, const char *funcname) |
