Class CharHeapPriorityQueue

    • Constructor Detail

      • CharHeapPriorityQueue

        public CharHeapPriorityQueue​(int capacity,
                                     CharComparator c)
        Creates a new empty queue with a given capacity and comparator.
        Parameters:
        capacity - the initial capacity of this queue.
        c - the comparator used in this queue, or null for the natural order.
      • CharHeapPriorityQueue

        public CharHeapPriorityQueue​(int capacity)
        Creates a new empty queue with a given capacity and using the natural order.
        Parameters:
        capacity - the initial capacity of this queue.
      • CharHeapPriorityQueue

        public CharHeapPriorityQueue​(CharComparator c)
        Creates a new empty queue with a given comparator.
        Parameters:
        c - the comparator used in this queue, or null for the natural order.
      • CharHeapPriorityQueue

        public CharHeapPriorityQueue()
        Creates a new empty queue using the natural order.
      • CharHeapPriorityQueue

        public CharHeapPriorityQueue​(char[] a,
                                     int size,
                                     CharComparator c)
        Wraps a given array in a queue using a given comparator.

        The queue returned by this method will be backed by the given array. The first size element of the array will be rearranged so to form a heap (this is more efficient than enqueing the elements of a one by one).

        Parameters:
        a - an array.
        size - the number of elements to be included in the queue.
        c - the comparator used in this queue, or null for the natural order.

        public CharHeapPriorityQueue​(char[] a,
                                     CharComparator c)
        Wraps a given array in a queue using a given comparator.

        The queue returned by this method will be backed by the given array. The elements of the array will be rearranged so to form a heap (this is more efficient than enqueing the elements of a one by one).

        Parameters:
        a - an array.
        c - the comparator used in this queue, or null for the natural order.

        Wraps a given array in a queue using the natural order.

        The queue returned by this method will be backed by the given array. The first size element of the array will be rearranged so to form a heap (this is more efficient than enqueing the elements of a one by one).

        Parameters:
        a - an array.
        size - the number of elements to be included in the queue.
      • CharHeapPriorityQueue

        public CharHeapPriorityQueue​(char[] a)
        Wraps a given array in a queue using the natural order.

        The queue returned by this method will be backed by the given array. The elements of the array will be rearranged so to form a heap (this is more efficient than enqueing the elements of a one by one).

        Parameters:
        a - an array.
      • CharHeapPriorityQueue

        public CharHeapPriorityQueue​(CharCollection collection,
                                     CharComparator c)
        Creates a queue using the elements in a type-specific collection using a given comparator.

        This constructor is more efficient than enqueing the elements of collection one by one.

        Parameters:
        collection - a collection; its elements will be used to initialize the queue.
        c - the comparator used in this queue, or null for the natural order.
      • CharHeapPriorityQueue

        public CharHeapPriorityQueue​(CharCollection collection)
        Creates a queue using the elements in a type-specific collection using the natural order.

        This constructor is more efficient than enqueing the elements of collection one by one.

        Parameters:
        collection - a collection; its elements will be used to initialize the queue.

                                     CharComparator c)
        Creates a queue using the elements in a collection using a given comparator.

        This constructor is more efficient than enqueing the elements of collection one by one.

        Parameters:
