Example 1 with Serialization

use of org.gephi.utils.Serialization in project gephi by gephi.

the class FilterModelPersistenceProvider method readXML.

public void readXML(XMLStreamReader reader, FilterModelImpl model) throws XMLStreamException {
    Serialization serialization = new Serialization(model.getGraphModel());
    Map<Integer, Query> idMap = new HashMap<>();
    boolean end = false;

                        }
                    } else {
                        model.getLibrary().saveQuery(query);
                    }
                }
            }
        } else if (eventType.equals(XMLStreamReader.END_ELEMENT)) {
            if ("filtermodel".equalsIgnoreCase(reader.getLocalName())) {
                end = true;
            }
        }

    // Init filters
    Graph graph;
    graph = model.getGraphModel().getGraph();

Example 2 with Serialization

use of org.gephi.utils.Serialization in project gephi by gephi.

the class FilterModelPersistenceProvider method writeQuery.

private void writeQuery(String code, XMLStreamWriter writer, FilterModelImpl model, Query query, int parentId) throws XMLStreamException {
    Serialization serialization = new Serialization(model.getGraphModel());
    writer.writeStartElement(code);
    int id = queryId++;
    writer.writeAttribute("id", String.valueOf(id));
    if (parentId != -1) {
        writer.writeAttribute("parent", String.valueOf(parentId));
    }
    Filter filter = query.getFilter();
    FilterBuilder builder = model.getLibrary().getBuilder(filter);
    writer.writeAttribute("builder", builder.getClass().getName());
    writer.writeAttribute("filter", filter.getClass().getName());
    if (query.getName() != null) {
        writer.writeAttribute("name", query.getName());
    }
    // Params
    for (int i = 0; i < query.getPropertiesCount(); i++) {
        FilterProperty prop = query.getFilter().getProperties()[i];
        writeParameter(writer, i, prop, serialization);
    }
    writer.writeEndElement();
    for (Query child : query.getChildren()) {
        writeQuery(code, writer, model, child, id);
    }
