- Method Detail
  - clear
```
void clear()
```
    Clears the model history. See also Model.resetHist() for how to generate a shorter, but still functional history.
  - complete
```
void complete(boolean isComplete)
```
    Enables or disables history logging for certain methods where the arguments typically are very large objects.
    
    Parameters:
    
    isComplete - true for complete logging.
  - disable
```
void disable()
```
    Disables logging of top-level API calls to the history. Use this method sparingly; the normal state is that everything should be logged. The recommended usage pattern is to use a try-finally block as follows:
    
    try { model.hist().disable(); // perform transient operations here but do not log them // ... } finally { model.hist().enable(); }
    Calling disable() can be viewed as adding an entry to a stack of disable records; logging will only occur if the stack is empty.
  - enable
```
void enable()
```
    Removes the most recent disabling of top-level API calls to the history. Calling enable() can be viewed as removing an entry from a stack of disable records; logging will only occur if the stack is empty.
  - isComplete
```
boolean isComplete()
```
    Checks if the history logging performs complete logging.
    
    Returns:
    
    true if logging is complete.
