# Blocking vs Non-blocking

The default behavior of the ring buffer is non-blocking, 
meaning that reads and writes will return immediately with an error if the operation cannot be completed.
If you want to block when reading or writing, you must enable it:

```go
	rb := ringbuffer.New(1024).SetBlocking(true)
```

      // while starting case.
      if (snapshot.state != STARTING) {
        IllegalStateException failure =
            new IllegalStateException(
                "Cannot notifyStarted() when the service is " + snapshot.state);
        notifyFailed(failure);
        throw failure;
      }

      if (snapshot.shutdownWhenStartupFinishes) {

        try {
            return (ConflictResolver) container.lookup(ConflictResolver.ROLE, type);
        } catch (ComponentLookupException exception) {
            throw new ConflictResolverNotFoundException("Cannot find conflict resolver of type: " + type);
        }
    }
