Reads a JSON representation and returns an IVML graph.

Parameters:

graph - the graph to read

Returns:

the IVML graph representation

Throws:

ExecutionException - if parsing graph fails

private void readEdges(Object id,
 org.json.simple.JSONObject node,
 boolean inputEdges)

Reads the edges for id/node.

Parameters:

id - the node id

node - the node

inputEdges - are we reading input or output edges
