pipeExist-method

[retog]

Currently in SourcingAdmin:

private boolean pipeExists(UriRef pipeRef) {
    boolean result = false;

    if (pipeRef != null) {
        GraphNode pipeNode = new GraphNode(pipeRef, getDlcGraph());
        if(pipeNode != null) {
            result = true;
        }
    }

    return result;

}

This is the same as:

private boolean pipeExists(UriRef pipeRef) {
   return pipreRef != null;
}

But probably what you want is something like

private boolean pipeExists(UriRef pipeRef) {
    boolean result = false;        
    if (pipeRef != null) {
        GraphNode pipeNode = new GraphNode(pipeRef, getDlcGraph());
        result = pipeNode.hasProperty(RDF.type, Ontology.Pipe);
    }
    return result;
}
