GDSL Awesomeness – Adding Hinting for missingMethod implementation

24 / Sep / 2012 by Kushal Likhi 0 comments

hi,

 

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${it.name}", params: [step: Integer], type: 'int')
  }
}

The above script will give autoCompletes for these dynamic methods.
