+<div class="sectionbody">
+<div class="sect2">
+<h3 id="_overview">Overview</h3>
+<div class="paragraph">
+<p>All configuration in Tamaya is expressed as simple key, value pairs. Nevertheless this concept allows similarly
+the modelling of collection typed values such as lists, sets, maps or simple collections of things. The Tamaya
+Collections extension adds this functionality to the Tamaya eco-system.</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_compatibility">Compatibility</h3>
+<div class="paragraph">
+<p>The module is based on Java 7, so it will not run on Java 7 and beyond.</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_installation">Installation</h3>
+<div class="paragraph">
+<p>To use Tamaya collection support you only must add the corresponding dependency to your module:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code class="language-xml" data-lang="xml">&lt;dependency&gt;
+  &lt;groupId&gt;org.apache.tamaya.ext&lt;/groupId&gt;
+  &lt;artifactId&gt;tamaya-collections&lt;/artifactId&gt;
+  &lt;version&gt;{tamaya_version}&lt;/version&gt;
+&lt;/dependency&gt;</code></pre>
+</div>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_overview_2">Overview</h3>
+<div class="paragraph">
+<p>Tamaya Collections adds PropertyConverter implementations that are able to access configuration data
+as lists, maps or sets. By default this works out of the box as easy as accessing any other type of
+configuration data, e.g.</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code class="language-java" data-lang="java">Configuration config = ConfigurationProvider.getConfiguration();
+
+// Without any content specification, a list of String is returned.
+List&lt;String&gt; simpleList = config.get("my.list.config.entry", List.class);
+
+// Using a TypeLiteral allows to use every convertible sub type supported by the system.
+List&lt;Integer&gt; intList = config.get("my.list.config.entry", new TypeLiteral&lt;List&lt;Integer&gt;&gt;(){});</code></pre>
+</div>
+</div>
+<div class="paragraph">
+<p>Configuration in that case, by default, is a simple comma-separated list of entries, e.g.</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code class="language-properties" data-lang="properties">my.list.config.entry=1,34454,23,344545,3445</code></pre>
+</div>
+</div>
+<div class="paragraph">
+<p>Additionally the module allows adding additional meta-entries, which allows to tweak some of the
+inner-workings, e.g.</p>
+</div>
+<div class="ulist">
+<ul>
+<li>
+<p>using your own PropertyConverter implementation for parsing entries.</p>
+</li>
+<li>
+<p>specifying a custom separator String to be used to split the items (default is {{','}}.</p>
+</li>
+<li>
+<p>specifying a custom separator String to be used to split key/value paris when parsing map entries.</p>
+</li>
+<li>
+<p>specifying the implementation type of the collection instance to be returned.</p>
+</li>
+<li>
+<p>specifying if the resulting collection should be returned as a modifiable collection.</p>
+</li>
+</ul>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_supported_types">Supported Types</h3>
+<div class="paragraph">
+<p>This module supports the following types:</p>
+</div>
+<div class="ulist">
+<ul>
+<li>
+<p>java.util.Collection</p>
+</li>
+<li>
+<p>java.util.List</p>
+</li>
+<li>
+<p>java.util.ArrayList</p>
+</li>
+<li>
+<p>java.util.LinkedList</p>
+</li>
+<li>
+<p>java.util.Set</p>
+</li>
+<li>
+<p>java.util.SortedSet</p>
+</li>
+<li>
+<p>java.util.TreeSet</p>
+</li>
+<li>
+<p>java.util.HashSet</p>
+</li>
+<li>
+<p>java.util.Map</p>
+</li>
+<li>
+<p>java.util.SortedMap</p>
+</li>
+<li>
+<p>java.util.HashMap</p>
+</li>
+<li>
+<p>java.util.TreeMap</p>
+</li>
+</ul>
+</div>
+<div class="paragraph">
+<p>Hereby the type is determined primarly by the parameter type accessed, e.g.
+config.get("mylist", ArrayList.class) will always return an ArrayList
+as result.</p>
+</div>
+<div class="sect3">
+<h4 id="_configuring_the_target_implementation_type">Configuring the target implementation type</h4>
+<div class="paragraph">
+<p>Tamaya Collections allows you to configure the target collection type by adding the
+following meta-configuration entry (shown for the mylist entry). Hereby the package part java.util.
+can be ommitted:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code class="language-properties" data-lang="properties">mylist=a,b,c
+_mylist.collection-type=LinkedList</code></pre>
+</div>
+</div>
+<div class="paragraph">
+<p>When calling config.get("mylist", ArrayList.class) this parameter does not have any effect, so you will still
+get an ArrayList as a result. However when you call config.get("mylist", List.class) you will
+get a LinkedList as implementation type.</p>
+</div>
+<div class="paragraph">
+<p>This mechanism similarly applies to all kind of collections, so you can use it similarly to define the implementation
+type returned when accessing List, Map or Collection.</p>
+</div>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_collecting_configuration_entries_instead_of_overriding">Collecting Configuration Entries instead of Overriding</h3>
+<div class="paragraph">
+<p>By default Tamaya applies always an overriding CombinationPolicy, where only the configuration entry for
+the most significant configuration entry is used. In case of collections (and maybe also other use cases),
+overriding is not always the mechanism of choice. E.g. when you want to have all entries added to your
+configuration to be <strong>combined</strong> to a new entry containing all values provided by any property sources.</p>
+</div>
+<div class="paragraph">
+<p>Therefore Tamaya Collections also provides a more sophistiated CombinationPolicy (automatically configured)
+that allows to adapt the way how configuration entries are combined. All you must do is declaring
+the mechanism to be applied by an according meta-configuration parameter, e.g. for my.list your config may
+look as follows:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code class="language-properties" data-lang="properties"># from PropertSource 1
+my.list=1,2,3
+
+# from PropertSource 2
+my.list=4,5,6
+
+# without any additional meta-info these entries would be combined to
+my.list=4,5,6</code></pre>
+</div>
+</div>
+<div class="paragraph">
+<p>With Tamaya Collections you can now configure the combination policy as follows:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code class="language-properties" data-lang="properties"># use one of the default policies: override / collect
+_my.list.combination-policy=collect
+
+# use an custom CombinationPolicy to combine the values
+_my.list.combination-policy=com.mycomp.app.MyCombincationPolicy</code></pre>
+</div>
+</div>
+<div class="paragraph">
+<p>So declaring the collect policy the resulting raw output of the entry looks as follows:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code class="language-properties" data-lang="properties"># result when applying the collect policy:
+my.list=1,2,3,4,5,6</code></pre>
+</div>
+</div>
+<div class="paragraph">
+<p>The customizable policy mechanism of Tamaya Collections also honors the item-separator meta-configuration
+parameter explained later in this document.</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_format_of_collection_configuration">Format of Collection Configuration</h3>
+<div class="paragraph">
+<p>By default collections are modelled as simple String values, that are tokenized into individual parts using a
+defined item-separator (by default ','). So a given configuration entry of 1,2,3 is mapped to "1","2","3".
+If the target context type is something different than String the smae conversion logic is used as when mapping
+configuration parameters directly to non-String target types (implemented as +PropertyConverter classes, manahed
+within the current ConfigurationContext. The procedure is identical for all collection types, including Map types,
+with the difference that each token in the list is parsed once more for separating it into a key and a value.
+The default separator for map entries hereby is "::". Map keys, as of now, are always of type String, whereas
+for values the same logic is applied as for non-map collection types.</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code class="language-properties" data-lang="properties"># a list, using the default format
+list=1,2,3,4,5,6
+
+# a map, using the default format
+map=a::b, c::d</code></pre>
+</div>
+</div>
+<div class="sect3">
+<h4 id="_trimming_of_entries">Trimming of entries</h4>
+<div class="paragraph">
+<p>By default all tokens parsed are trimmed <em>before</em> adding them to the final collection. In case of map entries this is
+also the case for key/value entries. So the following configuration results in the identical values for
+list1,list2 and map1,map2:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code class="language-properties" data-lang="properties"># a list, using the default format
+list1=1,2,3,4,5,6
+list2=1, 2, 3, 4, 5, 6
+
+# a map, using the default format
+map1=a::b, c::d
+map2=a :: b, c :: d</code></pre>
+</div>
+</div>
+<div class="paragraph">
+<p>Nevertheless truncation can be controlled by the usage of brackets, e.g. the last list or map entry will have a single
+space character as value:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code class="language-properties" data-lang="properties"># a list, with a ' ' value at the end
+list3=1, 2, 3, 4, 5, [ ]
+
+# a map, with a ' ' value for key '0'
+map3=1 :: a, 2 :: b, 0::[ ]</code></pre>
+</div>
+</div>
+<div class="paragraph">
+<p>Hereby \[ escapes the sequence.</p>
+</div>
+</div>
+<div class="sect3">
+<h4 id="_customizing_the_format">Customizing the format</h4>
+<div class="paragraph">
+<p>The item and entry separators (by default ',' and "::") can be customized by setting corresponding meta-data
+entries as follows, resulting in the same values as in the prevoius listing:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code class="language-properties" data-lang="properties"># a list, with a ' ' value at the end

+                    the name of Apache Incubator. Incubation is required of

+<p>The Tamaya consul integration module provides different artifacts which allows integration of Apachae Tamaya
+configuration with consul. Basically the module supports read-only integration (as a ConsulPropertySource as well
+as a support for MutableConfiguration as defined by the tamaya-mutable-config extension module.</p>

+</div>
+</div>
+<div class="sect2">
+<h3 id="_the_extensions_provided">The Extensions Provided</h3>
+<div class="paragraph">
+<p>Consul integration comes basically with 2 artifacts:</p>
+</div>
+<div class="ulist">
+<ul>
+<li>
+<p>The org.apache.tamaya.etcd.ConsulPropertySource is a PropertySource with a default ordinal of 100 and the name
+'consul', which is automatically registered.</p>
+</li>
+<li>
+<p>If the tamaya-mutable-config module is loaded it is possible to write property values back into the consul cluster,
+by accessing a MutableConfiguration using the URI config:consul.</p>
+</li>
+</ul>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_the_consulpropertysource">The ConsulPropertySource</h3>
+<div class="paragraph">
+<p>The ConsulPropertySource is automatically registered and allows the consul servers to be used to be configured. This
+enables to use e.g. in Docker environments the docker environment configuration mechanisms to configure Tamaya running
+in microservice containers to connect with the according consul cluster:</p>
+</div>
+<div class="ulist">
+<ul>
+<li>
+<p>The property source reads the tamaya.consul.urls system and environment property to evaluate possible etcd servers
+(comma separated), which can be connected to. On error the API just performs a Round-Robin through the list of
+configured servers. Without any configuration http://127.0.0.1:2400 is used. If no connection to any consul
+server can be established a warning will be logged, but deployment will not fail.</p>
+</li>
+<li>
+<p>The ConsulPropertySource finally also allows the values read from the consul cluster to be mapped to prefixed
+context. This can be activated by setting the -Dtamaya.consul.prefix=&lt;PREFIX&gt; system property. E.g. when the prefix is
+set to cluster-config. a consul key of host:known/all is mapped to cluster-config.host:known/all.</p>

+<p>The EtcdPropertySource finally also allows the values read from the etcd cluster to be mapped to prefixed

+                    The Apache Software Foundation (ASF), sponsored by
+                    the name of Apache Incubator. Incubation is required of
+                    all newly accepted projects until a further review indicates

+                    the code, it does indicate that the project has yet to
