BufferStrategy

Type Parameters:

T - items emitted from the Publisher which are to be buffered using this BufferStrategy.

BC - An intermediate mutable object that holds the items into a buffer before it is emitted.

B - The buffer of items.
```
public interface BufferStrategy<T,BC extends BufferStrategy.Accumulator<T,B>,B>
```
A strategy for buffering items emitted from a Publisher.
A buffer strategy represents asynchronous buffer boundaries over which items from a Publisher are buffered. Each item emitted from the boundary Publisher represents the end of the last boundary and start of the next boundary. The first item emitted from this Publisher is treated as the start of the first boundary and Publisher.buffer(BufferStrategy) may decide to defer requesting items from the Publisher on which that operator is applied.

- Method Detail
  - boundaries
```
Publisher<BC> boundaries()
```
    Returns a Publisher representing asynchronous buffer boundaries. This Publisher is expected to be an infinite Publisher. Hence, it should never terminate any PublisherSource.Subscriber subscribed to it. Instead PublisherSource.Subscribers will always cancel their PublisherSource.Subscription. If this expectation is violated, buffered items may be discarded.
    
    Returns:
    
    A Publisher representing asynchronous buffer boundaries.
  - bufferSizeHint
```
int bufferSizeHint()
```
    A rough estimate of the number of items in a buffer.
    
    Returns:
    
    A rough estimate of the number of items in a buffer.
