search - Adding an element to a VP tree (VP tree maintenance)

Question

I have read few sources on VP-tree for similarity knn. No one wrote about adding an element to exists tree, which is required for maintenance. Explanation of adding element will be just great.

Answer 1

add

public boolean add(E point)

Adds a single point to this vp-tree. Addition of a point executes in O(log n) time in the best case (where n is the number of points in the tree), but may also trigger a node partition that takes additional time.

Specified by:
    add in interface Collection<E extends GeospatialPoint>
Parameters:
    point - the point to add to this tree
Returns:
    true if the tree was modified by the addition of this point; vp-trees are always modified by adding points, so this method always returns true

addAll

public boolean addAll(Collection<? extends E> points)

Adds all of the points in the given collection to this vp-tree.

Specified by:
    addAll in interface Collection<E extends GeospatialPoint>
Parameters:
    points - the points to add to this tree
Returns:
    true if the tree was modified by the addition of the points; vp-trees are always modified by adding points, so this method always returns true
