Types

type PriorityQueue

type PriorityQueue[T any] struct {
	// contains filtered or unexported fields
}

func NewPriorityQueue

func NewPriorityQueue[T any](capacity int, compare containerx.Comparator[T]) *PriorityQueue[T]

NewPriorityQueue 创建优先队列 capacity <= 0 时，为无界队列，否则为有界队列

func (*PriorityQueue[T]) Cap

func (p *PriorityQueue[T]) Cap() int

Cap 无界队列返回0，有界队列返回创建队列时设置的值

func (*PriorityQueue[T]) Dequeue

func (p *PriorityQueue[T]) Dequeue() (T, error)

func (*PriorityQueue[T]) Enqueue

func (p *PriorityQueue[T]) Enqueue(t T) error

func (*PriorityQueue[T]) IsBoundless

func (p *PriorityQueue[T]) IsBoundless() bool

func (*PriorityQueue[T]) Len

func (p *PriorityQueue[T]) Len() int

func (*PriorityQueue[T]) Peek

func (p *PriorityQueue[T]) Peek() (T, error)
