| <FONT color="green">030</FONT> * Substitutes variables within a string by values.<a name="line.30"></a> |
| <FONT color="green">031</FONT> * <p><a name="line.31"></a> |
| <FONT color="green">032</FONT> * This class takes a piece of text and substitutes all the variables within it.<a name="line.32"></a> |
| <FONT color="green">033</FONT> * The default definition of a variable is <code>${variableName}</code>.<a name="line.33"></a> |
| <FONT color="green">034</FONT> * The prefix and suffix can be changed via constructors and set methods.<a name="line.34"></a> |
| <FONT color="green">035</FONT> * <p><a name="line.35"></a> |
| <FONT color="green">036</FONT> * Variable values are typically resolved from a map, but could also be resolved<a name="line.36"></a> |
| <FONT color="green">037</FONT> * from system properties, or by supplying a custom variable resolver.<a name="line.37"></a> |
| <FONT color="green">038</FONT> * <p><a name="line.38"></a> |
| <FONT color="green">039</FONT> * The simplest example is to use this class to replace Java System properties. For example:<a name="line.39"></a> |
| <FONT color="green">040</FONT> * <pre><a name="line.40"></a> |
| <FONT color="green">041</FONT> * StrSubstitutor.replaceSystemProperties(<a name="line.41"></a> |
| <FONT color="green">042</FONT> * "You are running with java.version = ${java.version} and os.name = ${os.name}.");<a name="line.42"></a> |
| <FONT color="green">043</FONT> * </pre><a name="line.43"></a> |
| <FONT color="green">044</FONT> * <p><a name="line.44"></a> |
| <FONT color="green">045</FONT> * Typical usage of this class follows the following pattern: First an instance is created<a name="line.45"></a> |
| <FONT color="green">046</FONT> * and initialized with the map that contains the values for the available variables.<a name="line.46"></a> |
| <FONT color="green">047</FONT> * If a prefix and/or suffix for variables should be used other than the default ones,<a name="line.47"></a> |
| <FONT color="green">048</FONT> * the appropriate settings can be performed. After that the <code>replace()</code><a name="line.48"></a> |
| <FONT color="green">049</FONT> * method can be called passing in the source text for interpolation. In the returned<a name="line.49"></a> |
| <FONT color="green">050</FONT> * text all variable references (as long as their values are known) will be resolved.<a name="line.50"></a> |
| <FONT color="green">051</FONT> * The following example demonstrates this:<a name="line.51"></a> |
| <FONT color="green">052</FONT> * <pre><a name="line.52"></a> |
| <FONT color="green">053</FONT> * Map valuesMap = HashMap();<a name="line.53"></a> |
| <FONT color="green">054</FONT> * valuesMap.put(&quot;animal&quot;, &quot;quick brown fox&quot;);<a name="line.54"></a> |
| <FONT color="green">055</FONT> * valuesMap.put(&quot;target&quot;, &quot;lazy dog&quot;);<a name="line.55"></a> |
| <FONT color="green">056</FONT> * String templateString = &quot;The ${animal} jumped over the ${target}.&quot;;<a name="line.56"></a> |
| <FONT color="green">057</FONT> * StrSubstitutor sub = new StrSubstitutor(valuesMap);<a name="line.57"></a> |
| <FONT color="green">058</FONT> * String resolvedString = sub.replace(templateString);<a name="line.58"></a> |
| <FONT color="green">059</FONT> * </pre><a name="line.59"></a> |
| <FONT color="green">060</FONT> * yielding:<a name="line.60"></a> |
| <FONT color="green">061</FONT> * <pre><a name="line.61"></a> |
| <FONT color="green">062</FONT> * The quick brown fox jumped over the lazy dog.<a name="line.62"></a> |
| <FONT color="green">063</FONT> * </pre><a name="line.63"></a> |
| <FONT color="green">064</FONT> * <p><a name="line.64"></a> |
| <FONT color="green">065</FONT> * In addition to this usage pattern there are some static convenience methods that<a name="line.65"></a> |
| <FONT color="green">066</FONT> * cover the most common use cases. These methods can be used without the need of<a name="line.66"></a> |
| <FONT color="green">067</FONT> * manually creating an instance. However if multiple replace operations are to be<a name="line.67"></a> |
| <FONT color="green">068</FONT> * performed, creating and reusing an instance of this class will be more efficient.<a name="line.68"></a> |
| <FONT color="green">069</FONT> * <p><a name="line.69"></a> |
| <FONT color="green">070</FONT> * Variable replacement works in a recursive way. Thus, if a variable value contains<a name="line.70"></a> |
| <FONT color="green">071</FONT> * a variable then that variable will also be replaced. Cyclic replacements are<a name="line.71"></a> |
| <FONT color="green">072</FONT> * detected and will cause an exception to be thrown.<a name="line.72"></a> |
| <FONT color="green">073</FONT> * <p><a name="line.73"></a> |
| <FONT color="green">074</FONT> * Sometimes the interpolation's result must contain a variable prefix. As an example<a name="line.74"></a> |
| <FONT color="green">075</FONT> * take the following source text:<a name="line.75"></a> |
| <FONT color="green">076</FONT> * <pre><a name="line.76"></a> |
| <FONT color="green">077</FONT> * The variable ${${name}} must be used.<a name="line.77"></a> |
| <FONT color="green">078</FONT> * </pre><a name="line.78"></a> |
| <FONT color="green">079</FONT> * Here only the variable's name referred to in the text should be replaced resulting<a name="line.79"></a> |
| <FONT color="green">080</FONT> * in the text (assuming that the value of the <code>name</code> variable is <code>x</code>):<a name="line.80"></a> |
| <FONT color="green">081</FONT> * <pre><a name="line.81"></a> |
| <FONT color="green">082</FONT> * The variable ${x} must be used.<a name="line.82"></a> |
| <FONT color="green">083</FONT> * </pre><a name="line.83"></a> |
| <FONT color="green">084</FONT> * To achieve this effect there are two possibilities: Either set a different prefix<a name="line.84"></a> |
| <FONT color="green">085</FONT> * and suffix for variables which do not conflict with the result text you want to<a name="line.85"></a> |
| <FONT color="green">086</FONT> * produce. The other possibility is to use the escape character, by default '$'.<a name="line.86"></a> |
| <FONT color="green">087</FONT> * If this character is placed before a variable reference, this reference is ignored<a name="line.87"></a> |
| <FONT color="green">088</FONT> * and won't be replaced. For example:<a name="line.88"></a> |
| <FONT color="green">089</FONT> * <pre><a name="line.89"></a> |
| <FONT color="green">090</FONT> * The variable $${${name}} must be used.<a name="line.90"></a> |
| <FONT color="green">091</FONT> * </pre><a name="line.91"></a> |
| <FONT color="green">092</FONT> * <p><a name="line.92"></a> |
| <FONT color="green">093</FONT> * In some complex scenarios you might even want to perform substitution in the<a name="line.93"></a> |
| <FONT color="green">094</FONT> * names of variables, for instance<a name="line.94"></a> |
| <FONT color="green">095</FONT> * <pre><a name="line.95"></a> |
| <FONT color="green">096</FONT> * ${jre-${java.specification.version}}<a name="line.96"></a> |
