This is a very special <a class="normal" href="CastleScript.html">CastleScript</a> value, used to represent user-defined function parameter. This poses itself as a <a class="normal" href="CastleScript.TCasScriptValue.html">TCasScriptValue</a> descendant, and it has working <a class="normal" href="CastleScript.TCasScriptParameterValue.html#AssignValue">AssignValue</a> and everything else. This way it can be used in &quot;Variables&quot; list for various <a class="normal" href="CastleScriptParser.html">CastleScriptParser</a> functions.
 
25
 
 
26
<p>Except it's cheating: it doesn't actually store the value. Instead, it has <a class="normal" href="CastleScript.TCasScriptParameterValue.html#SourceValue">SourceValue</a> property that is used when doing <a class="normal" href="CastleScript.TCasScriptParameterValue.html#AssignValue">AssignValue</a>. So <a class="normal" href="CastleScript.TCasScriptParameterValue.html#AssignValue">AssignValue</a> is handled by SourceValue.AssignValue, and Execute is handled by SourceValue.Execute, and so reading/writing this works.
 
27
 
 
28
<p>The advantage: the exact type of function parameter is not known, and still we can parse the function expression. This is crucial for parser implementation: when parsing you need to create <code>TCasScriptParameterValue</code> instance, but you don't know actual type of parameter that will be passed here.</p>
