ConcurrentLinkedQueue重要方法: Add()和offer()都是加入元素的方法(在ConcurrentLinkedQueue中,这两个方法投有任何区别) Poll()和peek()都是取头元素节点,区别在于前者会删除元素,后者不会 2.PriorityQueue, (优先级队列) Priority queue represented as a balanced binary heap: the two* children of queue[n] ...
需要注意的是，在多线程环境下，如果需要使用线程安全的队列，可以使用ConcurrentLinkedQueue、ArrayBlockingQ...

* Priority queue represented as a balanced binary heap: the two * children of queue[n] are queue[2*n+1] and queue[2*(n+1)]. The * priority queue is ordered by comparator, or by the elements' * natural ordering, if comparator is null: For each node n in the ...
boolean retainAll(Collection c):移除此collection中未包含在指定collection中的所有元素。集合A和集合B做交集,最终的结果保存在集合A,返回值表示的是A是否发生过变化。 举例: + View Code 举例:集合的遍历 初始化: + View Code 4. 迭代器(Iterator)
Returns as an option the first element for which f evaluates to true. val find_map : 'a t -> f:('a -> 'b option) -> 'b option Returns the first evaluation of f that returns Some, and returns None if there is no such element. ...
A lightweight linked list type queue implementation, meant for microcontrollers. Written as a C++ template class. Constructors Creates a queue up to<maximum_number_of_items>items: ArduinoQueue<T>intQueue(maximum_number_of_items); Creates a queue up to<maximum_size_in_bytes>bytes: ...
A linked queue, implemented as a singly linked list, offering O(1) time complexity for enqueue and dequeue operations. The queue maintains pointers to both the head (front) and tail (end) of the list for efficient operations without the need for traversal. package main import ( "fmt" "git...
