```
public boolean dependsOn(Graph other)

```
    Description copied from interface: Graph
    
    Answer true iff the graph contains a triple matching (s, p, o). s/p/o may be concrete or fluid. Equivalent to find(s,p,o).hasNext, but an implementation is expected to optimise this in easy cases.
    
    Specified by:
    
    contains in interface Graph
  - contains
```
public boolean contains(Triple t)
```
    Description copied from interface: Graph

    contains in interface Graph

    isClosed in interface Graph
  - isEmpty
```

    Description copied from interface: Graph
    
    Answer true iff this graph is empty. "Empty" means "has as few triples as it can manage", because an inference graph may have irremovable axioms and their consequences.

    isEmpty in interface Graph
  - size
```
public int size()
```
    Description copied from interface: Graph
    
    For a concrete graph this returns the number of triples in the graph. For graphs which might infer additional triples it results an estimated lower bound of the number of triples. For example, an inference graph might return the number of triples in the raw data graph.
    
    Specified by:
    
    size in interface Graph
