Usage

From source file:de.clusteval.framework.repository.config.RepositoryConfig.java

/**
 * This method parses a repository configuration from the file at the given
 * absolute path./*  w  ww  .j  a v a2s .  c o m*/
 * 
 * <p>
 * A repository configuration contains several sections and possible
 * options:
 * <ul>
 * <li><b>[mysql]</b></li>
 * <ul>
 * <li><b>host</b>: The ip address of the mysql host server.</li>
 * <li><b>database</b>: The mysql database name.</li>
 * <li><b>user</b>: The username used to connect to the database.</li>
 * <li><b>password</b>: The mysql password used to connect to the database.
 * The password is prompted from the console and not parsed from the file.</li>
 * </ul>
 * <li><b>[threading]</b></li>
 * <li><b>NameOfTheThreadSleepTime</b>: Sleeping time of the thread
 * 'NameOfTheThread'. This option can be used to control the frequency, with
 * which the threads check for changes on the filesystem.</li> </ul>
 * 
 * @param absConfigPath
 *            The absolute path of the repository configuration file.
 * @return The parsed repository configuration.
 * @throws RepositoryConfigNotFoundException
 * @throws RepositoryConfigurationException
