Ruben Laguna updated GROOVY-8408:
---------------------------------
Description:
In the Groovy in Action book, chapter 8.4.5 says
{quote}Category method names can well take the form of property accessors
(pretending property access), operator methods, and GroovyObject methods. MOP
hook methods cannot be added through a category class. This is a restriction as
of Groovy 2.4. The feature may become available in later versions.{quote}
It interpreted this as meaning that I can add GroovyMethods (getProperty,
getMetaClass, invokeMethod , setMetaClass and setProperty) to a class using
categories but not
methodMissing or propertyMissing (which I think they call MOP hook methods in
the GINA book).
But when I tried to add invokeMethod using a category the change has no effect,
adding missingMethod does not work either see attachement.
I see that methodsMissing/ propertyMissing via category was probably never
supported noted in GROOVY-3867. But the Groovy in Action paragraph makes me
think that invokeMethod et al were supported at some point.
