Functions | |
| static uint32_t | gserialized_get_uint32_t (const uint8_t *loc) |
| int | gserialized_has_bbox (const GSERIALIZED *gser) |
| Check if a GSERIALIZED has a bounding box without deserializing first. More... | |
| int | gserialized_has_z (const GSERIALIZED *gser) |
| Check if a GSERIALIZED has a Z ordinate. More... | |
| int | gserialized_has_m (const GSERIALIZED *gser) |
| Check if a GSERIALIZED has an M ordinate. More... | |
| int | gserialized_get_zm (const GSERIALIZED *gser) |
| Return a number indicating presence of Z and M coordinates. More... | |
| int | gserialized_ndims (const GSERIALIZED *gser) |
| Return the number of dimensions (2, 3, 4) in a geometry. More... | |
| int | gserialized_is_geodetic (const GSERIALIZED *gser) |
| Check if a GSERIALIZED is a geography. 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... | |
| uint32_t | gserialized_header_size (const GSERIALIZED *gser) |
| Returns the size in bytes of the header, from the start of the object up to the type number. More... | |
| uint32_t | gserialized_get_type (const GSERIALIZED *s) |

| int32_t | gserialized_get_srid (const GSERIALIZED *s) |
| 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 *s, 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_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... | |
| int | gserialized_read_gbox_p (const GSERIALIZED *g, GBOX *gbox) |

| static int | gserialized_peek_gbox_p (const GSERIALIZED *g, GBOX *gbox) |
| int | gserialized_get_gbox_p (const GSERIALIZED *g, GBOX *box) |
