Reference/es_mbi
struct es_mbi is an opaque data structure representing an iterator. An iterator is an object that can be used to traverse all the rows in a database node. It can be thought of as a pointer to a position in a database. Iterators are constructed with respect to a field-binding ( struct es_mbb ) and can be used to insert, update and fetch data.
| es_mbi_new | Construct a new iterator with respect to a field-binding. |
|---|---|
| es_mbi_delete | Delete an iterator. |
| es_mbi_copyrelfetch | Copy relative iterator position and fetch contents of row. |
| es_mbi_findfetch | Lookup row by index and fetch its contents. Set iterator to point at row. |
| es_mbi_findupdate | Lookup row by index and update it. Create row if it does not exist. Set iterator to point at row. |
| es_mbi_findremoveidx | Lookup row by index and update it. Remove row from index. Set iterator to point at row. |
| es_mbi_insert | Insert new row and update it. Set iterator to point at new row. For use with ES_INDEX_NONE index types with or without an index field. |
| es_mbi_fetch | Fetch row contents at current iterator position. |
| es_mbi_update | Update row contents at current iterator position. |
| es_mbi_begininit | Associate an iterator with a node but dont update its position. |
| es_mbi_beginfetch | Set iterator to point at the first row in node and fetch its contents. |
| es_mbi_incfetch | Increment iterator to point at the next row and fetch its contents. |
