Example 1 with ConfigurationManagementGraph

use of org.janusgraph.graphdb.management.ConfigurationManagementGraph in project janusgraph by JanusGraph.

the class ConfiguredGraphFactoryTest method shouldGetConfigurationManagementGraphInstance.

Example 2 with ConfigurationManagementGraph

use of org.janusgraph.graphdb.management.ConfigurationManagementGraph in project janusgraph by JanusGraph.

the class ConfiguredGraphFactory method createTemplateConfiguration.

/**
 * Create a template configuration according to the supplied {@link Configuration}; if
 * you already created a template configuration or the supplied {@link Configuration}
 * contains the property "graph.graphname", we throw a {@link RuntimeException}; you can then use
 * this template configuration to create a graph using the

Example 3 with ConfigurationManagementGraph

use of org.janusgraph.graphdb.management.ConfigurationManagementGraph in project janusgraph by JanusGraph.

the class ConfiguredGraphFactory method create.

 * graph and a {@link JanusGraph} graph reference according to the single
 * Template Configuration  previously created by the {@link ConfigurationManagementGraph} API;
 * A configuration for this graph must not already exist, and a Template Configuration must
 * exist. If the Template Configuration does not include its
 * backend's respective keyspace/table/storage_directory parameter, we set the keyspace/table
