contains method

  1. @override
bool contains(
  1. E object

Checks if object is in the queue.

Returns true if the element is found.

Uses the Object.== of elements in the queue to check for whether they are equal to object. Equal objects objects must have the same priority according to the comparison function. That is, if a == b then comparison(a, b) == 0. If that is not the case, this check might fail to find an object.


bool contains(E object) => _locate(object) >= 0;
