SingleMemoryAllocatorFactory (druid-processing 28.0.0 API)

java.lang.Object
- org.apache.druid.frame.allocation.SingleMemoryAllocatorFactory

All Implemented Interfaces:

MemoryAllocatorFactory
```
public class SingleMemoryAllocatorFactory
extends Object
implements MemoryAllocatorFactory
```
Wraps a single MemoryAllocator. The same instance is returned on each call to newAllocator(), after validating that it is 100% free. Calling newAllocator() before freeing all previously-allocated memory leads to an IllegalStateException.
