DeltaFIFO (Fabric8 :: Kubernetes :: Java Client 5.0.0-beta-1 API)

java.lang.Object
- io.fabric8.kubernetes.client.informers.cache.DeltaFIFO<T>

All Implemented Interfaces:

Store<Object>
```
public class DeltaFIFO<T>
extends Object
implements Store<Object>
```
The DeltaFIFO inherits from an Object queue since that we're actually reading from it as Deltas but writing it as Kubernetes object. This is taken from official client: https://github.com/kubernetes-client/java/blob/master/util/src/main/java/io/kubernetes/client/informer/cache/DeltaFIFO.java which is ported from official go client: https://github.com/kubernetes/client-go/blob/master/tools/cache/delta_fifo.go

```
- Method Detail
  - add
```
public void add(Object obj)
```
    Add items to the delta FIFO.
    
    Specified by:
    
    add in interface Store<Object>
    
    Parameters:
    
    obj - object
  - update
```
public void update(Object obj)
```
    Update items in delta FIFO
    
    Specified by:
    
    update in interface Store<Object>
    
    Parameters:
    
    obj - object
  - delete
```
public void delete(Object obj)
```
    Delete items from the delta FIFO
    
    Specified by:
    
    delete in interface Store<Object>
    
    Parameters:
