Constructor Detail

### XMLGraphReader

    public XMLGraphReader(PersistenceBindings bindings,
                          GraphManager manager)

  Constructs a new reader which reads a graph from an XML document. The roots of the result can be obtained by `getRoots()`. If the manager parameter is not null, all nodes will be added to the manager using the ids from the XML document.

  Parameters:
    `bindings` - bindings to use
    `manager` - if not null, add read nodes to manager with the ids from the XML document
