org.springmodules.validation.valang.javascript.ValangJavaScriptTranslator

Translates a collection of valang validation rules into a JavaScript statement that is capable of validating a HTML form and writes this to a provided Writer. This class is not thread safe so it is recommended that a new instance be created each time a translation is required.

The generated JavaScript code is dependent on the code base found in the file "valang_codebase.js" having already been loaded into the page where the validation will occur. @author Oliver Hutchison
