- Method Detail
  - performSingleOperation
```
void performSingleOperation(CacheWriter cacheWriter)
```
    Perform this operation as a single execution with the provided cache writer
    
    Parameters:
    
    cacheWriter - the cache writer this operation should be performed upon
  - createBatchOperation
```
BatchOperation createBatchOperation(java.util.List<? extends SingleOperation> operations)
```
    Creates a batch operation that corresponds to the operation type of this single operation.
    This batch operation will not be stored in the queue anymore and is solely used for structuring. The data from the single operation will already be processed in the final form that will be expected by the CacheWriter that will be used to execute the batch operation.
    
    Parameters:
    
    operations - the single operations that need to be regrouped in the batch operation
    
    Returns:
    
    the created batch operation
  - getType
```
SingleOperationType getType()
```
    Returns a stable identifier for the type this operation can be classified in. This is used to group and order batched operations.
    
    Returns:
    
    the identifier for this operation type
  - throwAway
```
void throwAway(CacheWriter cacheWriter,
               java.lang.RuntimeException e)
```
    Called when all retries have failed
    
    Parameters:
    
    cacheWriter - the CacheWriter to delegate to
    
    e - the last exception encountered
