ByteBufAllocator (Netty API Reference (4.0.56.Final))

All Known Implementing Classes:

AbstractByteBufAllocator, PooledByteBufAllocator, UnpooledByteBufAllocator
```
public interface ByteBufAllocator
```
Implementations are responsible to allocate buffers. Implementations of this interface are expected to be thread-safe.
