-<span class="sourceLineNo">081</span> * &lt;p&gt;<a name="line.81"></a>
-<span class="sourceLineNo">082</span> * In addition to this usage pattern there are some static convenience methods that<a name="line.82"></a>
-<span class="sourceLineNo">083</span> * cover the most common use cases. These methods can be used without the need of<a name="line.83"></a>
-<span class="sourceLineNo">084</span> * manually creating an instance. However if multiple replace operations are to be<a name="line.84"></a>
-<span class="sourceLineNo">085</span> * performed, creating and reusing an instance of this class will be more efficient.<a name="line.85"></a>
-<span class="sourceLineNo">086</span> * &lt;p&gt;<a name="line.86"></a>
-<span class="sourceLineNo">087</span> * Variable replacement works in a recursive way. Thus, if a variable value contains<a name="line.87"></a>
-<span class="sourceLineNo">088</span> * a variable then that variable will also be replaced. Cyclic replacements are<a name="line.88"></a>
-<span class="sourceLineNo">089</span> * detected and will cause an exception to be thrown.<a name="line.89"></a>
-<span class="sourceLineNo">090</span> * &lt;p&gt;<a name="line.90"></a>
-<span class="sourceLineNo">091</span> * Sometimes the interpolation's result must contain a variable prefix. As an example<a name="line.91"></a>
-<span class="sourceLineNo">092</span> * take the following source text:<a name="line.92"></a>
-<span class="sourceLineNo">093</span> * &lt;pre&gt;<a name="line.93"></a>
-<span class="sourceLineNo">094</span> *   The variable ${${name}} must be used.<a name="line.94"></a>
-<span class="sourceLineNo">095</span> * &lt;/pre&gt;<a name="line.95"></a>
-<span class="sourceLineNo">096</span> * Here only the variable's name referred to in the text should be replaced resulting<a name="line.96"></a>
-<span class="sourceLineNo">097</span> * in the text (assuming that the value of the &lt;code&gt;name&lt;/code&gt; variable is &lt;code&gt;x&lt;/code&gt;):<a name="line.97"></a>
-<span class="sourceLineNo">098</span> * &lt;pre&gt;<a name="line.98"></a>
-<span class="sourceLineNo">099</span> *   The variable ${x} must be used.<a name="line.99"></a>
-<span class="sourceLineNo">100</span> * &lt;/pre&gt;<a name="line.100"></a>
-<span class="sourceLineNo">101</span> * To achieve this effect there are two possibilities: Either set a different prefix<a name="line.101"></a>
-<span class="sourceLineNo">102</span> * and suffix for variables which do not conflict with the result text you want to<a name="line.102"></a>
-<span class="sourceLineNo">103</span> * produce. The other possibility is to use the escape character, by default '$'.<a name="line.103"></a>
-<span class="sourceLineNo">104</span> * If this character is placed before a variable reference, this reference is ignored<a name="line.104"></a>
-<span class="sourceLineNo">105</span> * and won't be replaced. For example:<a name="line.105"></a>
-<span class="sourceLineNo">106</span> * &lt;pre&gt;<a name="line.106"></a>
-<span class="sourceLineNo">107</span> *   The variable $${${name}} must be used.<a name="line.107"></a>
-<span class="sourceLineNo">108</span> * &lt;/pre&gt;<a name="line.108"></a>
-<span class="sourceLineNo">109</span> * &lt;p&gt;<a name="line.109"></a>
-<span class="sourceLineNo">110</span> * In some complex scenarios you might even want to perform substitution in the<a name="line.110"></a>
-<span class="sourceLineNo">111</span> * names of variables, for instance<a name="line.111"></a>
