Member Function Documentation

__renumber()

static ilDBUpdate4963::__renumber (   $node_id = 1,   $i = 1  )

staticprivate

This method is private.

Always call ilTree->renumber() since it locks the tree table renumber left/right values and close the gaps in numbers (recursive) @access private

Parameters

integer	node_id where to start (usually the root node)
integer	first left value of start node (usually 1)

Returns

integer current left value of recursive call
