DisjointUnion (Apache Jena)

- org.apache.jena.graph.impl.GraphBase
- - org.apache.jena.graph.compose.CompositionBase
  - - org.apache.jena.graph.compose.Dyadic
    - - org.apache.jena.graph.compose.DisjointUnion

All Implemented Interfaces:

Graph, GraphWithPerform
```
public class DisjointUnion
extends Dyadic
```
DisjointUnion - a version of Union that assumes the graphs are disjoint, and hence that find need not do duplicate-removal. Adding things to the graph adds them to the left component, and does not add triples that are already in the right component.

    Description copied from class: GraphBase
    
    Remove a triple from the triple store. The default implementation throws a DeleteDeniedException; subclasses must override if they want to be able to remove triples.
    
    Specified by:
    
    performDelete in interface GraphWithPerform
    
    Overrides:
    
    performDelete in class GraphBase
  - performAdd
```
public void performAdd(Triple t)
```
    Description copied from class: GraphBase
    
    Add a triple to the triple store. The default implementation throws an AddDeniedException; subclasses must override if they want to be able to add triples.
    
    Specified by:
    
    performAdd in interface GraphWithPerform
    
    Overrides:
