    • Method Detail

      • open

        public static Graph open​(org.apache.commons.configuration2.Configuration configuration)
        Open a graph. See each Graph instance for its configuration options.
        Parameters:
        configuration - A configuration object that specifies the minimally required properties for a Graph instance. This minimum is determined by the Graph instance itself.
        Returns:
        A Graph instance.
        Throws:
        IllegalArgumentException - if configuration

      • open

        public static Graph open​(String configurationFile)
        Open a graph. See each Graph instance for its configuration options. This file may be XML, YAML, or a standard properties file. How the configuration is used (and which kind is required) is dependent on the implementation.

        If using XML, ensure that the appropriate version of Apache commons-collections is available on the classpath as it is an optional dependency of Apache commons-configuration, the library that GraphFactory depends on.

        Parameters:
        configurationFile - The location of a configuration file that specifies the minimally required properties for a Graph instance. This minimum is determined by the Graph instance itself.
        Returns:
        A Graph instance.
        Throws:
        IllegalArgumentException - if configurationFile is null

      • open

        public static Graph open​(Map configuration)
        Open a graph. See each Graph instance for its configuration options.
        Parameters:
        configuration - A Map based configuration that will be converted to an Configuration object via MapConfiguration and passed to the appropriate overload.
        Returns:
        A Graph instance.
