public Timers timers
```
    Timers used in various different parts of KB. There may be many different timers created here depending on the level of debugging or application requirements. However, there are three major timers that are guaranteed to exist.
    - main - This is the main timer that exists in any Timers objects. All the other timers defined in here will have this timer as its dependant so setting a timeout on this timer will put a limit on every operation done inside KB.
    - preprocessing - This is the operation where TBox creation, absorbtion and normalization is done. It also includes computing hierarchy of properties in RBox and merging the individuals in ABox if there are explicit sameAs assertions.
    - consistency - This is the timer for ABox consistency check. Putting a timeout will mean that any single consistency check should be completed in a certain amount of time.

  - copy
```
public KnowledgeBase copy(boolean emptyABox)
```
    Create a copy of this KB. Depending on the value of emptyABox either a completely new copy of ABox will be created or the new KB will have an empty ABox. If emptyABox parameter is true but the original KB contains nominals in its RBox or TBox the new KB will have the definition of those individuals (but not ) In either case, the new KB will point to the same RBox and TBox so changing one KB's RBox or TBox will affect other.
    
    Parameters:
    
    emptyABox - If true ABox is not copied to the new KB
    
    Returns:

```
    Returns the (named) superclasses of class c. Depending on the second parameter the resulting list will include either all or only the direct superclasses. A class d is a direct superclass of c iff
    1. d is superclass of c
    2. there is no other class x such that x is superclass of c and d is superclass of x
    The class c itself is not included in the list but all the other classes that are sameAs c are put into the list. Also note that the returned list will always have at least one element. The list will either include one other concept from the hierarchy or the TOP concept if no other class subsumes c. By definition TOP concept is superclass of every concept.
    *** This function will first classify the whole ontology ***
    Parameters:
    
    c - class whose superclasses are returned
    
    Returns:
    
    A set of sets, where each set in the collection represents an equivalence class. The elements of the inner class are ATermAppl objects.
  - getSubClasses
```

Also note that the returned list will always have at least one element, that is the BOTTOM concept. By definition BOTTOM concept is subclass of every concept. This function is equivalent to calling getSubClasses(c, true).
    *** This function will first classify the whole ontology ***
    
    Parameters:
    
    c - class whose subclasses are returned
    
    Returns:

public void setExplainOnlyInconsistency(boolean explainOnlyInconsistency)
```
    Controls what kind of explanations can be generated using this KB. With this option enabled explanations for inconsistent ontologies will be returned. But if the ontology is consistent, it will not be possible to retrieve explanations for inferences about instances. This option is disabled by default. It should be turned on if explanations are only needed for inconsistencies but not other inferences. Turning this option on improves the performance of consistency checking for consistent ontologies.
    
    Parameters:
    
    explainOnlyInconsistency - new value for explainOnlyInconsistency option
