Method and apparatus for searching node by using tree index
2014
The present invention relates to a method and an apparatus for searching mode by using tree index. The node search method, comprising: setting a current time value as a traversing time value; searching descendent nodes to perform a traversing from a root node to a leaf node according to a tree index data structure; determining whether a preset traversing condition is satisfied by comparing an update time value, which indicates a time when a change to a searched descendent node is made, with the traversing time value; depending on whether the traversing proceeding condition is satisfied, re-performing a traversing from a parent node or continuing traversing to the searched descendent node; and terminating the traversing at a leaf node where no descendent node exists.
