Example 1 with DefaultGraphModel

use of org.neo4j.ogm.response.model.DefaultGraphModel in project neo4j-ogm by neo4j.

the class GraphModelAdapter method adapt.

/**
 * Parses a row from the result object and transforms it into a GraphModel

 * @param data the data to transform, given as a map
 * @return the data transformed to an {@link GraphModel}
 */
@Override

    // write the same node or relationship entity many times.

Example 2 with DefaultGraphModel

use of org.neo4j.ogm.response.model.DefaultGraphModel in project neo4j-ogm by neo4j.

the class GraphRowModelAdapter method adapt.

 * Reads the next row from the result object and transforms it into a RowModel object
 *
 * @param data the data to transform, given as a map
 * @return the data transformed to an {@link RowModel}

    Set<Long> edgeIdentities = new HashSet<>();
    DefaultGraphModel graphModel = new DefaultGraphModel();
    List<String> variables = new ArrayList<>();
    List<Object> values = new ArrayList<>();
    // there is no guarantee that the objects in the data are ordered the same way as required by the columns
    // so we use the columns information to extract them in the correct order for post-processing.
    Iterator<String> iterator = columns.iterator();
    adapt(iterator, data, graphModel, variables, values, nodeIdentities, edgeIdentities);
    DefaultRowModel rowModel = new DefaultRowModel(values.toArray(new Object[] {}), variables.toArray(new String[] {}));
