type ConcurrentMapShared ¶
type ConcurrentMapShared struct {

type Deque ¶
type Deque struct {
// contains filtered or unexported fields
}
Deque represents a single instance of the deque data structure.
func (*Deque) At ¶
At returns the element at index i in the queue without removing the element from the queue. This method accepts only non-negative index values. At(0) refers to the first element and is the same as Front(). At(Len()-1) refers to the last element and is the same as Back(). If the index is invalid, the call panics.
The purpose of At is to allow Deque to serve as a more general purpose circular buffer, where items are only added to and removed from the ends of the deque, but may be read from any place within the deque. Consider the case of a fixed-size circular log buffer: A new entry is pushed onto one end and when full the oldest is popped from the other end. All the log entries in the buffer must be readable without altering the buffer contents.
func (*Deque) Back ¶
func (q *Deque) Back() interface{}
Back returns the element at the back of the queue. This is the element that would be returned by PopBack(). This call panics if the queue is empty.
func (*Deque) Clear ¶
func (q *Deque) Clear()
Clear removes all elements from the queue, but retains the current capacity. This is useful when repeatedly reusing the queue at high frequency to avoid GC during reuse. The queue will not be resized smaller as long as items are only added. Only when items are removed is the queue subject to getting resized smaller.
func (*Deque) Front ¶
func (q *Deque) Front() interface{}
Front returns the element at the front of the queue. This is the element that would be returned by PopFront(). This call panics if the queue is empty.
func (*Deque) PopBack ¶
func (q *Deque) PopBack() interface{}
PopBack removes and returns the element from the back of the queue. Implements LIFO when used with PushBack(). If the queue is empty, the call panics.
func (*Deque) PopFront ¶
func (q *Deque) PopFront() interface{}
PopFront removes and returns the element from the front of the queue. Implements FIFO when used with PushBack(). If the queue is empty, the call panics.
func (*Deque) PushBack ¶
func (q *Deque) PushBack(elem interface{})
PushBack appends an element to the back of the queue. Implements FIFO when elements are removed with PopFront(), and LIFO when elements are removed with PopBack().
func (*Deque) PushFront ¶
func (q *Deque) PushFront(elem interface{})
PushFront prepends an element to the front of the queue.
func (*Deque) Rotate ¶
Rotate rotates the deque n steps front-to-back. If n is negative, rotates back-to-front. Having Deque provide Rotate() avoids resizing that could happen if implementing rotation using only Pop and Push methods.
func (*Deque) SetMinCapacity ¶
SetMinCapacity sets a minimum capacity of 2^minCapacityExp. If the value of the minimum capacity is less than or equal to the minimum allowed, then capacity is set to the minimum allowed. This may be called at anytime to set a new minimum capacity.
Setting a larger minimum capacity may be used to prevent resizing when the number of stored items changes frequently across a wide range.
