Overview

Package circularbuffer implements the circular buffer.

In computer science, a circular buffer, circular queue, cyclic buffer or ring buffer is a data structure that uses a single, fixed-size buffer as if it were connected end-to-end. This structure lends itself easily to buffering data streams.

Structure is not thread safe.

type Queue

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

Queue holds values in a slice.

func New

func New[T any](maxSize int) *Queue[T]

New instantiates a new empty queue with the specified size of maximum number of elements that it can hold. This max size of the buffer cannot be changed.

func NewFromIterator added in v0.15.0

func NewFromIterator[T any](maxSize int, it ds.ReadCompForIterator[T]) *Queue[T]

NewFromIterator instantiates a new queue containing the elements provided by the passed iterator.

FromJSON populates list's elements from the input JSON representation.

func (*Queue[T]) Full

func (queue *Queue[T]) Full() bool

Full returns true if the queue is full, i.e. has reached the maximum number of elements that it can hold.

func (*Queue[T]) GetValues added in v0.3.0

func (queue *Queue[T]) GetValues() []T

Values returns all elements in the queue (FIFO order).

func (*Queue[T]) IsEmpty added in v0.3.0

func (queue *Queue[T]) IsEmpty() bool

Empty returns true if queue does not contain any elements.

func (*Queue[T]) Last added in v0.15.0

func (queue *Queue[T]) Last() ds.ReadWriteOrdCompBidRandCollIterator[int, T]

Last returns an initialized iterator, which points to it's last element.

MarshalJSON @implements json.Marshaler

func (*Queue[T]) NewIterator added in v0.15.0

func (list *Queue[T]) NewIterator(list_ *Queue[T], index int) *Iterator[T]

NewIterator returns a stateful iterator whose values can be fetched by an index.

func (*Queue[T]) Peek

func (queue *Queue[T]) Peek() (value T, ok bool)

Peek returns first element of the queue without removing it, or nil if queue is empty. Second return parameter is true, unless the queue was empty and there was nothing to peek.

func (*Queue[T]) Size

func (queue *Queue[T]) Size() int

Size returns number of elements within the queue.

func (*Queue[T]) ToJSON
