--<div class="sectionbody">
--<div class="paragraph">
--<p>The fastest way to start with Tamaya is just using the <em>Core</em> implementation,
--implementing the <strong>API</strong> in small, minimalistic way. For that add the following
--Maven dependency to your project:</p>
--</div>
--<div class="listingblock">
--<div class="content">
--<pre class="prettyprint highlight"><code class="language-xml" data-lang="xml"><dependency>

-- <artifactId>tamaya-core</artifactId>
-- <version>0.3-SNAPSHOT</version>
--</dependency></code></pre>
--</div>
--</div>
--<div class="paragraph">
--<p>Given that you can add your configuration properties to the following locations in your classpath:</p>
--</div>
--<div class="listingblock">
--<div class="content">
--<pre class="prettyprint highlight"><code>META-INF/javaconfiguration.properties</code></pre>
--</div>
--</div>
--<div class="paragraph">
--<p>Additionally also system properties are taken into account, hereby overriding the default properties. Overall
--Tamaya by default defines the following configuration model per default (most significant first):</p>

--<div class="olist arabic">
--<ol class="arabic">
--<li>
--<p>System Properties</p>
--</li>
--<li>
--<p><code>META-INF/javaconfiguration.properties</code></p>
--</li>
--</ol>
--</div>
--<div class="paragraph">
--<p>There many modules that extend the capabilities of Tamaya.
--These modules doe not depend on core, so alternative
--implementations of the Tamaya API should work similarly.</p>
--</div>
--<div class="sect2">
--<h3 id="_multiple_configuration_files">Multiple configuration files</h3>
--<div class="paragraph">
--<p>By default you can provide multiple <code>javaconfig.properties</code> files, e.g. as part
--of multiple jars loaded into your system. The system internally creates one
--<code>PropertySource</code> for each file found on the classpath. All <code>PropertySource</code>
--instances created are ordered by their ordinal value (an int).</p>
--</div>
--<div class="paragraph">
--<p>Tamaya Core defines the following default ordinals (used, if no custom ordinal is defined):</p>
--</div>
--<table class="tableblock frame-all grid-all" style="width: 70%;">
--<colgroup>
--<col style="width: 75%;">

--<p>That means that the value of a configuration variable <code>x</code> overhanded via <code>-Dx=yes</code> has
--a higher precedence then the entry for configuration variable <code>x</code> specified in a <code>javaconfig.properties</code>
--as <code>x=no</code>.</p>
--</div>
--<div class="paragraph">
--<p>These ordinal values can be either hardcoded, or be dynamically

--Tamaya ordinal value as follows:</p>

--<pre class="prettyprint highlight"><code># override default Tamaya ordinal for property files

--<div class="paragraph">
--<p>Users want to be able to access configuration in a unified way both in SE and EE. EE may provide additional
--mechanism, such as injection, but the SE mechanisms should work as well, so any code written in SE is fully
--portable to EE as well.
--This can only be achieved by providing a static accessor, e.g.</p>
--</div>
--<div class="listingblock">
--<div class="content">
--<pre class="prettyprint highlight"><code class="language-java" data-lang="java">Configuration config = Configuration.current();</code></pre>
--</div>
--</div>
--<div class="paragraph">
--<p>The call above should work exactly the same in EE. To enable this the static call must be delegated in the
--internals of the singleton, depending on the runtime. In EE the executing component can behave contextually,
--or even be loaded within the CDI environment (at least for post loading, application runtime aspects, but not earlier).</p>
--</div>
--<div class="paragraph">
--<p>Additionally in EE it should also be possible to inject Configuration, which gives you the same results as the call
--above:</p>
--</div>
--<div class="listingblock">
--<div class="content">
--<pre class="prettyprint highlight"><code class="language-java" data-lang="java">@Inject

--<h3 id="_simple_lookup_of_properties">Simple Lookup of Properties</h3>
--<div class="paragraph">
--<p>Users just want to create a configuration ad hoc, from given property files. The
--files could be locally in the file system, on the classpath.</p>
--</div>
--<div class="paragraph">
--<p>Tamaya should provide a simple Java API for accessing key/value based configuration. Hereby users want to access
--properties as simple String values.</p>
--</div>
--<div class="paragraph">
--<p>Hereby returning Java 8 Optional values must be considered as well, instead of returning null.</p>

--<h3 id="_value_placeholders">Value Placeholders</h3>
--<div class="paragraph">
--<p>Users just want to to be able to add placeholders to the values of configuration (not the keys). The mechanisms for
--resolving the placeholders hereby should be not constraint to one single lanmguage like EL. Instead of different
--replacement strategies should be selectable, e.g. by prefixing an expression with the name of the resolver that
--should do the work (eg "blabla ${env:HOME} using Java version ${sys:java.version}.".
--This allows resolution mechanism to be isolated easily and also allows to use simpler mechanisms, if no more complex
--ones like EL are required. This is especially useful to deal with low resource environment like ME.</p>

--<div class="sect2">
--<h3 id="_type_safe_properties">Type Safe Properties</h3>
--<div class="paragraph">
--<p>Users just want to access properties not only as Strings, but let Tamaya do the conversion to the required
--or the configred target type. By defauklt all java.ui.lang wrapper and primitive types should be supported, but also
--other common types like date/time types, math numeric types and more.</p>
--</div>
--<div class="paragraph">
--<p>It must be possible that users can register their own custom types.</p>
--</div>

--<div class="sect2">
--<h3 id="_configuration_templates">Configuration Templates</h3>
--<div class="paragraph">
--<p>Users want to be able to let Tamaya implement an interface template based on configuration.
--This use case is pretty similar to the injection use case. Basically the values are not injected,
--but cached within the template proxy returned, e.g. as DynamicValue.
--Similarly it could even be possible to define callback methods (default methods)
--or register listeners to DynamicValue instances returned.</p>
--</div>
--<div class="paragraph">
--<p>Templates hereby can easily be managed, but provide a excellent mechanism to provide type-safe configuration
--to clients in a very transparent way. Details can be controlled by using the same annotations as for
--normal configuration injection.</p>

--<div class="sectionbody">
--<div class="sect2">
--<h3 id="_minimal">Minimal</h3>
--<div class="paragraph">
--<p>This example shows the basic functionality that is available when Tamaya is used without any further extensions.
--It shows how configuration can be added to the classpath and how it can be accessed.</p>
--</div>
--</div>
--<div class="sect2">
--<h3 id="_simple_propertysource">Simple PropertySource</h3>
--<div class="paragraph">
--<p>This example shows how to write and register an additional PropertySource and PropertySourceProvider, which is
--the SPI to add your own configuration data and locations. For a more advanced example you may also have a look at
--the provided default metamodels, e.g. the simple metamodel (currently in the experimental part and not shipped with
--the current release).</p>
--</div>
--</div>
--<div class="sect2">
--<h3 id="_resources">Resources</h3>
--<div class="paragraph">
--<p>This example shows how resources can be located using ANT-styled paths and this feature can help you to implement
--PropertySourceProvider instances that provide configuration for a set of files/folders at a certain (searchable)
--location, as provided by the resource extension_.</p>
--</div>
--</div>
--<div class="sect2">
--<h3 id="_resolver">Resolver</h3>
--<div class="paragraph">
--<p>The resolver example defines a configuration file that illustrates the usage of placeholders that are resolved on
--configuration access, as provided by the <em>resolver extension</em>.</p>
--</div>
--</div>
--<div class="sect2">
--<h3 id="_injection">Injection</h3>
--<div class="paragraph">
--<p>The injection sample shows how to inject configuration into a created object instance, or how to instantiate a proxied
--configuration template, which provides a type-safe configuration access mechanism. This functionality is provided
--by the <em>injection extension</em>. Hereby neither JSR 330 nor 299 are used, so it is pure and minimal SE based
--implementation.</p>
--</div>
--</div>
--<div class="sect2">
--<h3 id="_fileobserver">FileObserver</h3>
--<div class="paragraph">
--<p>This example shows how the event extension can be used to automatically adapt the current configuration when
--the underlying configuration data is changing, e.g. when new configuration is added to a file folder, or removed or
--adapted.</p>
--</div>
--</div>
--<div class="sect2">
--<h3 id="_builder">Builder</h3>
--<div class="paragraph">
--<p>This example shows how to build a Configuration using a simple pure SE builder API as provided by the
--<em>builder extension</em>.</p>
--</div>
--</div>
--<div class="sect2">
--<h3 id="_remote">Remote</h3>
--<div class="paragraph">
--<p>THe remote example shows a simple setup where parts of the Configuration are read remotedly.</p>
