Private Attributes | |
| btree::leaf_node * | currnode |

| Evil! A temporary value_type to STL-correctly deliver operator* and operator->. | |
Friends | |
| class | iterator |
| Friendly to the const_iterator, so it may access the two data items directly. | |
| class | const_iterator |
| Also friendly to the const_iterator, so it may access the two data items directly. | |
| class | const_reverse_iterator |
| Also friendly to the const_iterator, so it may access the two data items directly. | |
The iterator points to a specific slot number in a leaf.

Dereference the iterator.
Do not use this if possible, use key() and data() instead. The B+ tree does not stored key and data together.
