SharedByteArray

All Implemented Interfaces:

com.facebook.common.memory.MemoryTrimmable
```
@ThreadSafe() 
public class SharedByteArray
 implements MemoryTrimmable
                    
```
Maintains a shareable reference to a byte array.
When accessing the shared array proper synchronization is guaranteed. Under hood the get method acquires an exclusive lock, which is released whenever the returned CloseableReference is closed.
If the currently available byte array is too small for a request it is replaced with a bigger one.
This class will also release the byte array if it is unused and collecting it can prevent an OOM.
