GDSL Awesomeness – Adding Hinting for missingMethod implementation

24 / Sep / 2012 by Kushal Likhi 0 comments



Suppose we have used method missing in our code and we want to give syntax-hinting for these methods then we can go as follows:


Suppose we have this class which implements method missing:
class Pixel {
def Top
def Left
def Color
def methodMissing(String name, args) {
// implementation of dynamic method synthesis, it will intercept methods in signature increment<propertyName>(Integer step)


Now GDSL Script for the above class will be like:
def ctx = context(ctype: "my.package.Pixel")
contributor (ctx) {
// Add generic methods
classType?.fields?.each {
method(name: "increment${}", params: [step: Integer], type: ‘int’)
The above script will give autoCompletes for these dynamic methods.
