+/**
+ * This class is used to synchronize signaling of status between threads.
+ * <p>
+ * In complex multi-threaded applications it is often necessary to synchronize operations between threads. This is
+ * especially true in complex algorithms where processing dependencies exist between different threads and the
+ * synchronization of the operations of those threads is required. This class is a framework to enable multi-thread
+ * signaling and wait/post logic that makes the thread synchronization easier.
+ * </p>
+ * <p>
+ * Basically, in thread synchronization, one thread is the "waiter" and one or more other threads are the "notifiers".
+ * The notifiers send signals to the waiter to inform that thread that certain conditions are true, processing has been
+ * completed, or to inform the waiter of the state of the other thread(s). In the basic java framework, the waiter and
+ * notifier are simply using the wait/notify mechanism provided, which does not allow for different conditions, state,
+ * or "signals" to exist. The wait/notify mechanism, in combination with the object mutex, provides basic blocking and
+ * releasing of a thread's dispatching state.
+ * </p>
+ * <p>
+ * This class builds upon the java wait/notify mechanism and allows for "signals" to be defined. These signals are
+ * simply string constants that mean something to the waiter and notifier threads. Any number of signals may be defined,
+ * and it is possible to wait for more than one signal to be received, wait for any one of a set to be received, or to
+ * test if a signal has been received without blocking.
+ * </p>
+ * <p>
+ * Some operations are blocking operations. These stop the execution of the calling thread until the specified condition
+ * is true. These blocking methods are all named "wait...", such as {@link #waitFor(String...)} and
+ * {@link #waitForAny(String...)}. The thread making the call to these blocking methods MUST be the waiter thread (the
+ * thread registered with the signal object).
+ * </p>
+ * <p>
+ * Some operations are non-blocking. These operations allow for the testing or setting of signal conditions and do not
+ * block the caller. When calling these methods ({@link #isSignaled(String)}, {@link #signal(String)}, and
+ * {@link #setTimeout(long)} the waiter thread mutex will be held and may block the waiter thread for the duration of
+ * the method call.
+ * </p>

+/**
+ * The configuration factory is used to obtain access to an already created and initialized
+ * singleton configuration object as well as to create and initialize the singleton if not already
+ * set up.
+ * <p>
+ * This class is responsible for the creation of the configuration object used to manage the
+ * configuration of the application. The configuration object implementation must implement the
+ * <code>Configuration</code> interface. This allows for the factory to create different
+ * specializations in the future if needed and not break any application code.
+ * </p>
+ * <p>
+ * The configuration object is basically a wrapper around a properties object. The configuration is
+ * therefore specified as a set of properties that are loaded and processed from different sources
+ * with different precedences. It is important that the configuration object always be able to
+ * supply default values for any configuration properties that must be supplied, and not rely on the
+ * user always supplying these values. This also relieves the application itself from having to
+ * interpret missing or invalid properties and applying defaults. By having all of the defaults in
+ * one place, the application code can be simpler (not having to worry about defaults or invalid
+ * properties), and the defaults can be changed much easier (they are all in one place and not
+ * distributed throughout the codebase).
+ * </p>
+ * <p>
+ * Since the configuration is managed as a property object, we can use a characteristic of the
+ * <code>Properties</code> class to our advantage. Namely, if we put a property into a
+ * <code>Properties</code> object that already exists, the <code>Properties</code> object replaces
+ * it with the new value. This does not affect any other properties that may already be defined in
+ * the properties object. This gives us the ability to initialize the properties with default values
+ * for all of the application settings, then override just those that we need to override, possibly
+ * from multiple sources and in increasing order of precedence.
+ * </p>
+ * <p>
+ * This means that properties are in effect "merged" together from multiple sources in a prescribed
+ * precedence order. In fact, the precedence order that this factory implements is defined as:
+ * </p>
+ * <ol>
+ * <li>Default values from a system resource file.</li>
+ * <li>User-supplied properties file, if any.</li>
+ * <li>Application-supplied properties, if any.</li>
+ * <li>Command-line properties (if any)</li>
+ * </ol>
+ * <p>
+ * The name and location of the properties file that is loaded can also be set, either in the
+ * defaults, overridden by the system command line via -D, or as a system environment variable.
+ * There are two properties that can be specified to define the name and path. These are:
+ * </p>
+ * <dl>
+ * <dt>org.onap.appc.bootstrap.file</dt>
+ * <dd>This property defines the name of the file that will be loaded. If not specified, the default
+ * value is "appc.properties". This can be specified in either (or both) the default properties or
+ * the command line. The command line specification will always override.</dd>
+ * <dt>org.onap.appc.bootstrap.path</dt>
+ * <dd>This is a comma-delimited (,) path of directories to be searched to locate the specified
+ * file. The first occurrence of the file is the one loaded, and no additional searching is
+ * performed. The path can be specified in either, or both, the default values and the command line
+ * specification. If specified on the command line, the value overrides the default values. If
+ * omitted, the default path is <code>$/opt/onap/appc/data/properties,${user.home},.</code></dd>
+ * </dl>

+</head>
+
+<body>
+  <p style="margin-left: 30.0px;">
+    CDP Configuration support is provided by a common framework to load
+    and manage configuration properties from multiple sources. The basic
+    concept is to load a set of default properties from a known resource
+    file located on the class path, and then override these defaults
+    with optional settings that can be provided by a user through either
+    additional property files or via the command line (as VM arguments).
+    The loading of defaults from a resource property file (named <strong>com/att/cdp/default.properties</strong>)
+    ensures that values are defined for properties the application needs
+    in order to operate.
+  </p>
+  <p style="margin-left: 30.0px;">
+    One of these default values that can be set is the name of the
+    property file that allows the user to supply settings, as well as
+    the path where the file can be found. In general, the default name
+    of the property file will be &quot;<strong>cdp.properties</strong>&quot;,
+    and the path that will be searched is &quot;<strong>${user.home};etc;../etc</strong>&quot;.
+    However, these values can be changed through the use of the
+    default.properties resource file. The property that specifies the
+    property file name is named <strong>com.att.cdp.bootstrap.file</strong>,
+    while the property named <strong>com.att.cdp.bootstrap.path</strong>
+    specifies the search path.
+  </p>
+  <p style="margin-left: 30.0px;">
+    After the default.properties are loaded, but prior to searching for
+    the application configuration file, the configuration factory checks
+    for properties <strong>com.att.cdp.bootstrap.path</strong> and <strong>com.att.cdp.bootstrap.file
+    </strong>in the System properties object (meaning they were set by the
+    command line). If these values are defined in the system properties
+    object, they are used. If not, these values are obtained from the
+    default properties just loaded. This allows the specification of
+    either the file name or path, or both, to be overridden during start
+    up by using command-line arguments.
+  </p>
+  <p style="margin-left: 30.0px;">The search path is scanned for the
+    first occurrence of the specified property file. The first
+    occurrence is loaded and scanning is stopped at that point. The
+    configuration factory does not load all occurrences it finds, only
+    the first occurrence it finds.</p>
+  <p style="margin-left: 30.0px;">The configuration properties are
+    loaded and processed according to a defined precedence order, such
+    that properties defined with a higher precedence override the same
+    property at a lower precedence. The precedence order is defined as
+    follows:</p>
+  <h2>Precedence Order</h2>
+  <ol>
+    <li>Default properties are initially loaded into the
+      configuration. These default properties are the lowest level
+      precedence, and will be overridden by any properties specified at
+      higher levels. These are loaded from resources that are packaged
+      as part of the various application components. Each component
+      (Server, Coordinator, EPM, or CLI) may have different default
+      properties. The default properties are loaded from a resource
+      named <strong>com/att/cdp/default.properties</strong>. The default
+      properties can specify the name of the application property file
+      to be used to configure the application, as well as the path to
+      search. Additionally, these properties can be supplied via the
+      command line to override the default settings if needed.<br /> <br />
+    </li>
+    <li>The configuration factory allows for the application to
+      supply an initial properties object to initialize the
+      configuration. This properties object could be loaded or created
+      in any way necessary for the application. This is totally up to
+      the application to define, if it is needed. If no
+      application-specific property object is supplied, this step is
+      skipped. If a property object is supplied, it is used to replace
+      or set any properties that may have been defined by the defaults.<br />
+      <br />
+    </li>
+    <li>The configuration factory will then search for a bootstrap
+      file on a bootstrap path. The actual bootstrap file name and path
+      can be specified as properties on the command line, or will
+      default to a file name of <strong>cdp.properties</strong> and a
+      path of <strong>${user.home};etc;../etc</strong>. If desired, the
+      user can specify the exact name of the property file to be loaded
+      as well as the path using <strong>-Dcom.att.cdp.bootstrap.file=&lt;filename&gt;</strong>
+      and <strong>-Dcom.att.cdp.bootstrap.path=&lt;path&gt;</strong>.
+      These properties are set to default values by the default
+      properties loaded in step #1 above. The first occurrence of a
+      property file is the file loaded and used. Any other occurrences
+      are not processed.<br /> <br />
+    </li>
+    <li>The System properties are then merged into the
+      configuration. This allows the highest level of precedence,
+      command-line VM arguments (-D<strong>name=value</strong>) to be
+      merged into the configuration property object. These settings
+      override all lower level settings of the same name, as well as
+      merge all system properties into the configuration object.
+    </li>
+  </ol>
+  <h2>Variables</h2>
+  <p style="margin-left: 30.0px;">
+    The configuration support allows for variables to be inserted into
+    any property that is defined. Variables are named using the format <strong>${name}</strong>,
+    where the &quot;name&quot; is the name of a property that is defined
+    in the configuration, or a system property (such as <strong>user.home</strong>).
+    Variables can nest, such that a variable can be replaced with
+    another variable, which is then reevaluated to obtain the value.
+    This allows for indirection as well as variable substitution, if
+    needed.
+  </p>
+  <h2>Using the Configuration Support</h2>
+  <p style="margin-left: 30.0px;">
+    The configuration support was designed to be easy to use. The
+    configuration implementation is abstracted away from the application
+    so that it could be changed easily in the future if needed, or if we
+    needed to load different implementations for different reasons. This
+    means that the application always accesses the configuration through
+    an interface, named <strong>Configuration</strong>. The
+    implementation of that configuration interface is obtained by a
+    static method on the <strong>ConfigurationFactory</strong> class.
+    The configuration factory will both create the configuration if not
+    already created on the first access, as well as return the current
+    configuration if already created. Additionally, the
+    ConfigurationFactory provides mechanisms to recreate the
+    configuration after the application is initialized should the need
+    arise to update its configuration.
+  </p>
+  <p style="margin-left: 30.0px;">An example of the code needed to
+    obtain access to the configuration is:</p>
+  <pre style="margin-left: 30.0px;">Configuration config = ConfigurationFactory.getConfiguration();</pre>
+  <p style="margin-left: 30.0px;">Please refer to the javadoc or the
+    source code in cdp-common for other ways that the configuration and
+    configuration factory can be used.</p>
+  <h2>Reloading Properties</h2>
+  <p style="margin-left: 30.0px;">The configuration support allows
+    for properties to be re-loaded and re-evaluated after the
+    application is running. This is designed to allow a configuration to
+    be refreshed should the need arise. This could allow on-demand
+    refresh (via a command, for example), or automatically based on
+    sensing a change in the configuration file.</p>
+  <p style="margin-left: 30.0px;">
+    When the <strong>ConfigurationFactory</strong> method <strong>getConfiguration(Propert</strong><strong>ies)</strong>
+    is called, the current configuration is cleared and rebuilt using
+    the process defined above. The supplied property object is used in
+    step #2 of the process. While the properties are being re-built, no
+    access to the properties are allowed. Any attempt to access
+    properties while the re-build operation is in effect will block the
+    caller until completed. This is accomplished using read and write
+    shared locks.
+  </p>
