- Method Detail
  - getState
```
RegexPartitionState getState(Object key)
```
    Return state for key or create state if not found.
    
    Parameters:
    
    key - to look up
    
    Returns:
    
    state
  - getState
```
RegexPartitionState getState(EventBean theEvent,
                             boolean isCollect)
```
    Return state for event or create state if not found.
    
    Parameters:
    
    theEvent - to look up
    
    isCollect - true if a collection of unused state can occur
    
    Returns:
    
    state
  - removeOld
```
int removeOld(EventBean[] events,
              boolean isEmpty,
              boolean[] found)
```
    Remove old events from the state, applicable for "prev" function and partial NFA state.
    
    Parameters:
    
    events - to remove
    
    isEmpty - indicator if there are not matches
    
    found - indicator if any partial matches exist to be deleted
    
    Returns:
    
    number removed
  - copyForIterate
```
RegexPartitionStateRepo copyForIterate(boolean forOutOfOrderReprocessing)
```
    Copy state for iteration.
    
    Parameters:
    
    forOutOfOrderReprocessing - indicator whether we are processing out-of-order events
    
    Returns:
    
    copied state
  - removeState
