Package ring provides a simple implementation of a ring buffer.
|
|
|
|
## Usage
|
|
|
|
```go
|
|
var DefaultCapacity int = 10
|
|
```
|
|
The DefaultCapacity of an uninitialized Ring buffer.
|
|
|
|
Changing this value only affects ring buffers created after it is changed.
|
|
|
|
#### type Ring
|
|
|
|
```go
|
|
type Ring struct {
|
|
}
|
|
```
|
|
|
|
Type Ring implements a Circular Buffer. The default value of the Ring struct is
|
|
a valid (empty) Ring buffer with capacity DefaultCapacify.
|
|
|
|
#### func (Ring) Capacity
|
|
|
|
```go
|
|
func (r Ring) Capacity() int
|
|
```
|
|
Capacity returns the current capacity of the ring buffer.
|
|
|
|
#### func (*Ring) Dequeue
|
|
|
|
```go
|
|
func (r *Ring) Dequeue() interface{}
|
|
```
|
|
Dequeue a value from the Ring buffer.
|
|
|
|
Returns nil if the ring buffer is empty.
|
|
|
|
#### func (*Ring) Enqueue
|
|
|
|
```go
|
|
func (r *Ring) Enqueue(i interface{})
|
|
```
|
|
Enqueue a value into the Ring buffer.
|
|
|
|
#### func (*Ring) Peek
|
|
|
|
```go
|
|
func (r *Ring) Peek() interface{}
|
|
```
|
|
Read the value that Dequeue would have dequeued without actually dequeuing it.
|
|
|
|
Returns nil if the ring buffer is empty.
|
|
|
|
#### func (*Ring) SetCapacity
|
|
|
|
```go
|
|
func (r *Ring) SetCapacity(size int)
|
|
```
|
|
Set the maximum size of the ring buffer.
|
|
|
|
#### func (*Ring) Values
|
|
|
|
```go
|
|
func (r *Ring) Values() []interface{}
|
|
```
|
|
Values returns a slice of all the values in the circular buffer without
|
|
modifying them at all. The returned slice can be modified independently of the
|
|
circular buffer. However, the values inside the slice are shared between the
|
|
slice and circular buffer.
