Class PredefinedTypesConfig

java.lang.Object

org.hypergraphdb.util.PredefinedTypesConfig

public class PredefinedTypesConfig
extends Object

Utility to read and hold configuration of predefined HyperGraphDB types. A predefined types configuration file is a text file with the following format:

• Each line contains a single predefined type as a list of space-separated fields.
• The first field is the string representation of the persistent handle of the type.
• The second field is the Java class implementing the type. It must be a default constructible implementation of the HGAtomType interface.
• Finally, zero or more fields list every Java class that this type maps to.
• Lines starting with the pound sign # are ignored.
