Installation

$ npm install fibonacciheap

Methods

clear()

Clears the heap's data, making it an empty heap.

decreaseKey(node, newKey)

node: Node, the node to be decreased

newKey: number, the new key value

delete(node)

node: Node, the node to remove from the heap

extractMinimum()

Returns

Node, the node with the smallest key

findMinimum()

Returns

Node, the node with the smallest key

insert(key, value)

key: number,

value: object, any value associated with the node to insert

Returns

Node, the node that was inserted

isEmpty()

Returns

boolean, true if the heap is empty

size()

Returns

number, the amount of nodes in the heap

union(other)

other: FibonacciHeap, the FibonacciHeap to union with this one

compare(a, b)

a: Node, a node to compare

b: Node, a node to compare

Returns

number, 1 if a has a larger key than b, -1 if b has a larger key than a and 0 if they are equal
