expandometaclass

I'm working on a fresh Grails project and recently noticed the default convention in the Spring Security Core generated User class now auto-encodes the password via a beforeInsert/Update event. That's a nice, clean, DRY way of doing the encode, and also makes it impossible to forget to do so. However, now when trying to write up some unit tests which make use of said User class, I find I either have to mock out the springSecurityService (due to the encode), or more preferably (and cleanly), I'd just override the beforeInsert/Update closure with one that does nothing. Typically in Groovy one

I'd like some sorthand for this: Map rowToMap(row) { def rowMap = [:]; row.columns.each{ rowMap[it.name] = it.val } return rowMap; } given the way the GDK stuff is, I'd expect to be able to do something like: Map rowToMap(row) { row.columns.collectMap{ [it.name,it.val] } } but I haven't seen anything in the docs... am I missing something? or am I just way too lazy? epidemian I've recently came across the need to do exactly that: converting a list into a map. This question was posted before Groovy version 1.7.9 came out, so the method collectEntries didn't exist yet. It works exactly as the
