Interface BlockAllocatorRegistry

public interface BlockAllocatorRegistry

Used to track BlockAllocators in transactional environments where you want tighter control over how much memory a particular transaction uses. By using the same BlockAllocator for all resources in a given transaction you can limit the total memory used by that transaction. This also proves to be a useful mechanism to inject BlockAllocators in contexts which are difficult to access with more traditional dependency injection mechanism. One such example is in a ObjectMapper that is deserializing and incoming request.
