Module: JavaGettersAndSetters

Defined in:
lib/rpv/java/java_getters_and_setters.rb

Overview

Adds Java style getters and setters to your class. Maps (getFooBar, setFooBar, isFooBar) to (foo_bar, foo_bar=, foo_bar?). If a class implements method_missing, it should be included afterwards in order to preserve it by chaining the methods.
