Examples with DataType org.graphdrawing.graphml.DataType used on opensource projects

Example 1 with DataType

use of org.graphdrawing.graphml.DataType in project opennms by OpenNMS.

the class GraphMLReader method addProperties.

private static void addProperties(GraphMLElement graphElement, String elementId, Map<String, KeyType> keyIdToTypeMapping, List<DataType> elementData) throws InvalidGraphException {

Example 2 with DataType

use of org.graphdrawing.graphml.DataType in project opennms by OpenNMS.

the class GraphMLWriter method addProperties.
