Main question: What operators, properties, etc. can be used to determine the type of variables in Groovy? Background: I have an arbitrarily deeply-nested dictionary data structure. It is the result of calling request.JSON in a Grails controller. I would first like to verify certain keys are in the dictionary, with the appropriate types...

How can I intercept this call, and modify the parameter to parameter.absolutePath ? For example : def x = new File("some_file") ... def meth(de...
Grails provides filters that run before your controllers. They're defined in classes that look like this: class SecurityFilters { def filters = { myFilter(controller:'*', action:'*') { // What are those weird colons?? print "I'm filtering!" // Code that does the filtering goes here } } } These...

Hi, In Groovy you can do surprising type conversions using either the as operator or the asType method. Examples include Short s = new Integer(6) as Short List collection = new HashSet().asType(List) I'm surprised that I can convert from an Integer to a Short and from a Set to a List, because there is no "is a" relationship between t...
