hydra

Class ConfigHashtable

java.lang.Object

hydra.ConfigHashtable

All Implemented Interfaces:

Serializable

public class ConfigHashtable
extends Object
implements Serializable

Manages a HashMap used for storing hydra configuration settings. This class provides routines for retrieving string, int, long, and double representations of parameter values.

Note that if one of the "at" methods is invoked, but no value has been specified for the configuration parameter, a HydraConfigException is thrown.
