Method Detail

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getDepth

public int getDepth()

Specified by:

getDepth in class FingerTree<T,S>

getLeafCount

public int getLeafCount()

Specified by:

getLeafCount in class FingerTree<T,S>

asList

public java.util.List<T> asList()

Description copied from class: FingerTree

Returns a list view of this tree. Complexity of operations on the returned list:

• size(): O(1);
• get: O(log(n));
• iteration: O(n) in either direction, with O(log(n)) total allocations;
• subList: O(log(n));
• iterative subList, i.e. calling subList on the result of previous subList, up to n times: O(n).

Specified by:

asList in class FingerTree<T,S>

subList

private java.util.List<T> subList(int from,
                                  int to)

Complexity of calling once: O(log(n)). Complexity of calling subList recursively on the resulting list, i.e. tree.asList().subList(...).subList(...). ... .subList(...) up to n times: O(n). When the resulting list has size m, it may prevent up to m additional elements of the original tree from being garbage collected.
