/**
 * Abstract implementation of the <b>Container interface, providing common
 * functionality required by nearly every implementation.  Classes extending
 * this base class must implement <code>getInfo(), and may implement
 * a replacement for <code>invoke().
 * <p>
 * All subclasses of this abstract base class will include support for a
 * Pipeline object that defines the processing to be performed for each request
 * received by the <code>invoke() method of this class, utilizing the
 * "Chain of Responsibility" design pattern.  A subclass should encapsulate its
 * own processing functionality as a <code>Valve, and configure this
 * Valve into the pipeline by calling <code>setBasic().
 * <p>
 * This implementation fires property change events, per the JavaBeans design
 * pattern, for changes in singleton properties.  In addition, it fires the
 * following <code>ContainerEvent events to listeners who register
 * themselves with <code>addContainerListener():
 * <table border=1>
 *   <tr>
 *     <th>Type
 *     <th>Data
 *     <th>Description
 *   </tr>
 *   <tr>
