Examples with ReadConfiguration org.janusgraph.diskstorage.configuration.ReadConfiguration used on opensource projects

Example 1 with ReadConfiguration

use of org.janusgraph.diskstorage.configuration.ReadConfiguration in project janusgraph by JanusGraph.

the class JanusGraphFactory method getLocalConfiguration.

/**
 * Load a properties file containing a JanusGraph graph configuration.
 * <p>
 * <ol>
 * <li>Load the file contents into a {@link org.apache.commons.configuration2.PropertiesConfiguration}</li>
 * <li>For each key that points to a configuration object that is either a directory
 * or local file, check
 * whether the associated value is a non-null, non-absolute path. If so,
 * then prepend the absolute path of the parent directory of the provided configuration {@code file}.
 * This has the effect of making non-absolute backend
 * paths relative to the config file's directory rather than the JVM's
 * working directory.
 * <li>Return the {@link ReadConfiguration} for the prepared configuration file</li>
 * </ol>
 * <p>
 *
 * @param file A properties file to load
 * @return A configuration derived from {@code file}
