Examples of org.jruby.runtime.builtin.IRubyObject

org.jruby.runtime.builtin.IRubyObject
Object is the parent class of all classes in Ruby. Its methods are therefore available to all objects unless explicitly overridden.

    public IRubyObject flatten_bang(ThreadContext context) {
        int i = 0;
        RubyArray memo = null;


        while (i < realLength) {
            IRubyObject ary2 = values[begin + i];
            IRubyObject tmp = ary2.checkArrayType();
            if (!tmp.isNil()) {
                if (memo == null) {
                    memo = new RubyArray(getRuntime(), false);
                    memo.values = reserve(ARRAY_DEFAULT_SIZE);
                }
