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
