    Description copied from interface: CachedNode
    
    Returns if this node was cached without any dependency to a non-deterministic branch. In the presence of nominals, when we are checking the satisfiability of a concept the root node may be merged to a nominal node and that merge may be due to a non-deterministic branch. In such cases the types and edges that are cached do not necessarily show types and edges that will exist in every clash-free tableau completion.

    If this node was cached without any dependency to a non-deterministic branch

public final boolean hasRNeighbor(Role r)

    Description copied from interface: CachedNode
    
    Checks if this node is connected to another node with the given role (or one of its subproperties). The node may have an incoming edge with the inverse of this role which would count as an r-neighbor.
    
    Specified by:

  - hasDataPropertyValue
```
public Bool hasDataPropertyValue(Role r,
                                 Object value)
```
    Check the property assertions to see if it is possible for this individual to have the value for the given datatype property. This function is meaningful only called for individuals in a completed ABox (a pseudo model for the KB). In a completed ABox, individual will have some literal successors that may or may not have a known value. The individual has the data property value only if it has a literal successor that has the exact given value and the edge between the individual and the literal does not depend on any non- deterministic branch. If the literal value is there but the edge depends on a branch then we cannot exactly say if the literal value is there or not. If there is no literal successor with the given value then we can for sure say that individual does not have the data property value (because it does not have the value in at least one model)
    
    Parameters:
    
    r -
    
    value -
    
    Returns:
    
    Bool.TRUE if the individual definetely has the property value, Bool.FALSE if the individual definetely does NOT have the property value and Bool.UNKNOWN if it cannot be determined for sure, i.e. consistency check is required

  - getParent
```
public Individual getParent()
```
  - reset
```
public void reset(boolean onlyApplyTypes)
```
    Resets this node (types, edges, sames, differents) to contain only asserted information. This function can be seen a specialized case of restore but a special function is needed both for correctness (e.g. SMART_RESTORE option should not change behavior) and performance

  - removeEdge
```
public final boolean removeEdge(Edge edge)
```
  - prune
```
public void prune(DependencySet ds)
```
    Prune the given node by removing all links going to nominal nodes and recurse through all successors. No need to remove incoming edges because either the node is the first one being pruned so the merge function already handled it or this is a successor node and its successor is also being pruned
    
    Specified by:

    Returns:
    
    true if this is the cached node for TOP concept

    Returns if this is the cached node for BOTTOM concept.
    
    Specified by:
    
    isTop in interface CachedNode
    
    Returns:
