A JavaScript emulator of the TreeSet Java class
$ npm install ml-tree-set
TreeSet allows to create a sorted array of objects by adding each new element in order, according with the comparator function.
TreeSet does not really implements a tree to maintain the order. It just add the elements in the correct place in the array.
Nevertheless adding, removing or finding an element is guaranteed to be performed in log(n).
Unlike the other binary-tree implementations available in npm, this one allows repeated keys.
###constructor(comparator):
Create a new TreeSet object. The comparator gives the order to the set. By default it is the natural comparator
function(a, b){ return a - b };
Add an element to the sorted list
Return the number of elements in the set
Return the last element of the sorted list
Return the first element of the sorted list
Return and removes the last element of the sorted list
Return and removes the first element of the sorted list
Performs a binary search of value in array
##Example
const myList = new TreeSet(function( a, b){ return a.index - b.index; });
myList.add({index:0,value:"a"});
myList.add({index:3,value:"d"});
myList.add({index:2,value:"c"});
myList.pollFirst();
myList.add({index:1,value:"b"});
//The myList.elements should be: [{index:1,value:"b"},{index:2,value:"c"},{index:3,value:"d"}]);
//myList.size() should be equal to 3;
