+/**
+ * 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.openecomp.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.openecomp.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>$/opt/openecomp/appc/data/properties,${user.home},.</code></dd>
+ * </dl>

+<head>
+<title>Configuration</title>
+</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>
