by values.<a name="line.27"></a>
-<span class="sourceLineNo">028</span> * <p><a name="line.28"></a>
-<span class="sourceLineNo">029</span> * This class takes a piece of text and
substitutes all the variables within it.<a name="line.29"></a>
-<span class="sourceLineNo">030</span> * The default definition of a variable
is <code>${variableName}</code>.<a name="line.30"></a>
-<span class="sourceLineNo">031</span> * The prefix and suffix can be changed
via constructors and set methods.<a name="line.31"></a>
-<span class="sourceLineNo">032</span> * <p><a name="line.32"></a>
-<span class="sourceLineNo">033</span> * Variable values are typically resolved
from a map, but could also be resolved<a name="line.33"></a>
-<span class="sourceLineNo">034</span> * from system properties, or by
supplying a custom variable resolver.<a name="line.34"></a>
-<span class="sourceLineNo">035</span> * <p><a name="line.35"></a>
-<span class="sourceLineNo">036</span> * The simplest example is to use this
class to replace Java System properties. For example:<a name="line.36"></a>
-<span class="sourceLineNo">037</span> * <pre><a name="line.37"></a>
-<span class="sourceLineNo">038</span> *
StrSubstitutor.replaceSystemProperties(<a name="line.38"></a>

-<span class="sourceLineNo">041</span> * <p><a name="line.41"></a>
-<span class="sourceLineNo">042</span> * Typical usage of this class follows
the following pattern: First an instance is created<a name="line.42"></a>
-<span class="sourceLineNo">043</span> * and initialized with the map that
contains the values for the available variables.<a name="line.43"></a>
-<span class="sourceLineNo">044</span> * If a prefix and/or suffix for
variables should be used other than the default ones,<a name="line.44"></a>
-<span class="sourceLineNo">045</span> * the appropriate settings can be
performed. After that the <code>replace()</code><a
name="line.45"></a>
-<span class="sourceLineNo">046</span> * method can be called passing in the
source text for interpolation. In the returned<a name="line.46"></a>
-<span class="sourceLineNo">047</span> * text all variable references (as long
as their values are known) will be resolved.<a name="line.47"></a>

this:<a name="line.48"></a>

-<span class="sourceLineNo">062</span> * Also, this class allows to set a

-<span class="sourceLineNo">063</span> * The default value for a variable can
be appended to the variable name after the variable<a name="line.63"></a>
-<span class="sourceLineNo">064</span> * default value delimiter. The default
value of the variable default value delimiter is ':-',<a name="line.64"></a>

those are arguably where the default ${} delimiter set originated.<a

-<span class="sourceLineNo">080</span> * </pre><a name="line.80"></a>
-<span class="sourceLineNo">081</span> * <p><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> * <p><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> * <p><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> * <pre><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> * </pre><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 <code>name</code> variable is <code>x</code>):<a
name="line.97"></a>
-<span class="sourceLineNo">098</span> * <pre><a name="line.98"></a>
-<span class="sourceLineNo">099</span> * The variable ${x} must be used.<a
name="line.99"></a>
-<span class="sourceLineNo">100</span> * </pre><a name="line.100"></a>
-<span class="sourceLineNo">101</span> * To achieve this effect there are two
possibilities: Either set a different prefix<a name="line.101"></a>
-<span class="sourceLineNo">102</span> * and suffix for variables which do not
conflict with the result text you want to<a name="line.102"></a>
-<span class="sourceLineNo">103</span> * produce. The other possibility is to
use the escape character, by default '$'.<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> * <pre><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> * </pre><a name="line.108"></a>
-<span class="sourceLineNo">109</span> * <p><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>
-<span class="sourceLineNo">112</span> * <pre><a name="line.112"></a>
-<span class="sourceLineNo">113</span> * ${jre-${java.specification.version}}<a
