Examples with DataStoreFactory org.apache.jackrabbit.core.data.DataStoreFactory used on opensource projects

Example 1 with DataStoreFactory

use of org.apache.jackrabbit.core.data.DataStoreFactory in project jackrabbit by apache.

the class RepositoryConfigurationParser method parseRepositoryConfig.

/**
     * Parses repository configuration. Repository configuration uses the
     * following format:
     * <pre>
     *   &lt;Repository&gt;
     *     &lt;FileSystem ...&gt;
     *     &lt;Security appName="..."&gt;
     *       &lt;SecurityManager ...&gt;
     *       &lt;AccessManager ...&gt;
     *       &lt;LoginModule ... (optional)&gt;
     *     &lt;/Security&gt;
     *     &lt;Workspaces rootPath="..." defaultWorkspace="..."/&gt;
     *     &lt;Workspace ...&gt;
     *     &lt;Versioning ...&gt;
     *   &lt;/Repository&gt;
     * </pre>
     * <p>
     * The <code>FileSystem</code> element is a
     * {@link #parseBeanConfig(Element,String) bean configuration} element,
     * that specifies the file system implementation for storing global
     * repository information. The <code>Security</code> element contains
     * an <code>AccessManager</code> bean configuration element and the
     * JAAS name of the repository application. The <code>Workspaces</code>
     * element contains general workspace parameters, and the
     * <code>Workspace</code> element is a template for the individual
     * workspace configuration files. The <code>Versioning</code> element
     * contains
     * {@link #parseVersioningConfig(Element) versioning configuration} for
     * the repository.
     * <p>
     * In addition to the configured information, the returned repository
     * configuration object also contains the repository home directory path
     * that is given as the ${rep.home} parser variable. Note that the
     * variable <em>must</em> be available for the configuration document to
     * be correctly parsed.
     * <p>
     * {@link #replaceVariables(String) Variable replacement} is performed
     * on the security application name attribute, the general workspace
     * configuration attributes, and on the file system, access manager,
     * and versioning configuration information.
     * <p>
     * Note that the returned repository configuration object has not been
     * initialized.
     *
     * @param xml repository configuration document
     * @return repository configuration
     * @throws ConfigurationException if the configuration is broken
     * @see #parseBeanConfig(Element, String)
     * @see #parseVersioningConfig(Element)
