/**
 * Resource type descriptors for all resources in the VFS.<p>
 *
 * Each file in the VFS must belong to an initialized resource type.
 * The available resource type are read during system startup from the configuration
 * file <code>opencms-vfs.xml</code>.<p>
 *
 * Certain resource types may require special handling for certain operations.
 * This is usually required for write operations, or other operations that
 * modify the VFS database.
 * Therefore, the {@link org.opencms.file.CmsObject} defers handling of this
 * operations to implementations of this interface.<p>
 *
 * If you implement a new resource type, it's a good idea to extend the
 * abstract class {@link org.opencms.file.types.A_CmsResourceType}.<p>
 *
 * Important: The {@link org.opencms.file.CmsObject} passes the {@link org.opencms.db.CmsSecurityManager}
 * object to implementations of this class. Using this object correctly is key to the
 * resource type operations. Mistakes made in the implementation of a resource type
 * can screw up the system security and the database structure, and make you unhappy. <p>
