Ruben Laguna created GROOVY-8408: ------------------------------------ Summary: invokeMethod cannot be set through category Key: GROOVY-8408 URL: https://issues.apache.org/jira/browse/GROOVY-8408 Project: Groovy Issue Type: Bug Affects Versions: 2.6.0-alpha-2, 2.4.13, 3.x, 2.5.x Reporter: Ruben Laguna Attachments: categoryMissingMethod.groovy
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.
