>DESCRIPTION</a></h1>

<p>Lintian::DepMap::Properties is a simple layer between Lintian::DepMap and the application allowing nodes to have application-defined properties.</p>

<dl>
<dt><a name="add(node,_[dependencies],_[ref_to_property])"
>add(node, [dependencies], [ref to property])</a></dt>

<dd>
<p>Adds a node with possibly one or more dependencies and sets the <code>node</code>&#39;s property to the ref, if defined. The property must be a reference (it can be to a hash, an array, a function, an object, etc) and must be the last argument given to the method.</p>

<p>E.g.</p>

<pre>    $map-&#62;add(&#39;foo&#39;, {name =&#62; &#39;John Doe&#39;, age =&#62; 20});</pre>

<dt><a name="addp(node[,_prefix,_dependency[,_dependency...]],_[ref_to_property])"
>addp(node[, prefix, dependency[, dependency...]], [ref to property])</a></dt>

<dd>
<p>Adds the given <code>node</code> to the map marking any third or more parameters, after prefixing them with <code>prefix</code>, as its dependencies and sets the <code>node</code>&#39;s property to the ref, if defined. See add()&#39;s description for more information about properties. E.g.</p>

<pre>    # pA and pB have no dependency:
    $map-&#62;addp(&#39;pA&#39;, {name =&#62; &#39;John Doe&#39;});
    $map-&#62;addp(&#39;pB&#39;, {name =&#62; &#39;Jane Doe&#39;});
    # Df depends on pA and pB:
    $map-&#62;addp(&#39;Df&#39;, &#39;p&#39;, &#39;A&#39;, &#39;B&#39;, {name =&#62; &#39;Doe Family&#39;});</pre>

<dt><a name="getp(node)"
>getp(node)</a></dt>

<dd>
<p>Returns the reference to the given <code>node</code>&#39;s properties.</p>

<p>E.g.</p>

<pre>    # prints John Doe
    print $map-&#62;getp(&#39;foo&#39;)-&#62;{&#39;name&#39;};
    # changes the value of &#39;name&#39;
    $map-&#62;getp(&#39;foo&#39;)-&#62;{&#39;name&#39;} = &#39;Jane Doe&#39;;
    # prints Jane Doe
    print $map-&#62;getp(&#39;foo&#39;)-&#62;{&#39;name&#39;};</pre>
