Public Instance Methods

native_impl(lib) click to toggle source

Causes a Java class to be instantiated instead of the Ruby class when running on JRuby. This is used to test both pure Java and pure Ruby classes from the same Ruby based test suite. The Java Class must have a package name that corresponds with the Ruby class.

# File lib/gherkin/native/java.rb, line 24
def native_impl(lib)
  require "#{lib}.jar"

  class << self
    def new(*args)
      begin
        java_class.new(*javaify(args))
      rescue ArgumentError => e
        e.message << "\n#{java_class.name}"
        raise e
      rescue NameError => e
        e.message << "\n args: #{args.inspect}"
        raise e
      end
    end
