Data Structures | |
| struct | wkb_parse_state |
| Used for passing the parse state between the parsing functions. More... | |
Functions | |
| LWGEOM * | lwgeom_from_wkb_state (wkb_parse_state *s) |
| Internal function declarations. More... | |
| uint8_t * | bytes_from_hexbytes (const char *hexbuf, size_t hexsize) |
| static void | wkb_parse_state_check (wkb_parse_state *s, size_t next) |
| Check that we are not about to read off the end of the WKB array. More... | |
| static void | lwtype_from_wkb_state (wkb_parse_state *s, uint32_t wkb_type) |
| Take in an unknown kind of wkb type number and ensure it comes out as an extended WKB type number (with Z/M/SRID flags masked onto the high bits). More... | |
| static char | byte_from_wkb_state (wkb_parse_state *s) |
| Byte Read a byte and advance the parse state forward. More... | |
| static uint32_t | integer_from_wkb_state (wkb_parse_state *s) |
| Int32 Read 4-byte integer and advance the parse state forward. More... | |
| static double | double_from_wkb_state (wkb_parse_state *s) |
| Double Read an 8-byte double and advance the parse state forward. More... | |
| static POINTARRAY * | ptarray_from_wkb_state (wkb_parse_state *s) |
| POINTARRAY Read a dynamically sized point array and advance the parse state forward. More... | |
| static LWPOINT * | lwpoint_from_wkb_state (wkb_parse_state *s) |
| POINT Read a WKB point, starting just after the endian byte, type number and optional srid number. More... | |
| static LWLINE * | lwline_from_wkb_state (wkb_parse_state *s) |
| LINESTRING Read a WKB linestring, starting just after the endian byte, type number and optional srid number. More... | |
| static LWCIRCSTRING * | lwcircstring_from_wkb_state (wkb_parse_state *s) |
| CIRCULARSTRING Read a WKB circularstring, starting just after the endian byte, type number and optional srid number. More... | |
| static LWPOLY * | lwpoly_from_wkb_state (wkb_parse_state *s) |
| POLYGON Read a WKB polygon, starting just after the endian byte, type number and optional srid number. More... | |
| static LWTRIANGLE * | lwtriangle_from_wkb_state (wkb_parse_state *s) |
| TRIANGLE Read a WKB triangle, starting just after the endian byte, type number and optional srid number. More... | |
| static LWCURVEPOLY * | lwcurvepoly_from_wkb_state (wkb_parse_state *s) |
| CURVEPOLYTYPE. More... | |
| static LWCOLLECTION * | lwcollection_from_wkb_state (wkb_parse_state *s) |
| POLYHEDRALSURFACETYPE. More... | |
| LWGEOM * | lwgeom_from_wkb (const uint8_t *wkb, const size_t wkb_size, const char check) |
| WKB inputs must have a declared size, to prevent malformed WKB from reading off the end of the memory segment (this stops a malevolent user from declaring a one-ring polygon to have 10 rings, causing the WKB reader to walk off the end of the memory). More... | |
| LWGEOM * | lwgeom_from_hexwkb (const char *hexwkb, const char check) |
Variables | |
| static uint8_t | hex2char [256] |
