Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`ByteBuf`	`allocate()`	Creates a new receive buffer to use by the buffer ring.
`default void`	`allocateBatch(java.util.function.Consumer<ByteBuf> consumer, int num)`	Fill in `num` of `ByteBuf`s.
`void`	`lastBytesRead(int attempted, int actual)`	Set the bytes that have been read for the last read operation that was full-filled out of the buffer ring.

- Method Detail
  - allocate
```
ByteBuf allocate()
```
    Creates a new receive buffer to use by the buffer ring. The returned ByteBuf must be direct.
  - lastBytesRead
```
void lastBytesRead(int attempted,
                   int actual)
```
    Set the bytes that have been read for the last read operation that was full-filled out of the buffer ring.
    
    Parameters:
    
    attempted - the attempted bytes to read.
    
    actual - the number of bytes that could be read.
  - allocateBatch
```
default void allocateBatch(java.util.function.Consumer<ByteBuf> consumer,
                           int num)
```
    Fill in num of ByteBufs. Important: The Consumer MUST not escape this method.
    
    Parameters:
    
    consumer - the Consumer that will consume the buffers.
    
    num - the number of buffers that are passed to Consumer.accept(Object).
