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 select(ThreadContext context, Block block) {
        Ruby runtime = context.getRuntime();
        final RubyArray result;
        if (regs == null) {
            if (begin < 0) return runtime.newEmptyArray();
            IRubyObject s = str.substr(runtime, begin, end - begin);
            s.setTaint(isTaint());
            result = block.yield(context, s).isTrue() ? runtime.newArray(s) : runtime.newEmptyArray();
        } else {
            result = runtime.newArray();
            boolean taint = isTaint();
            for (int i = 0; i < regs.numRegs; i++) {
                IRubyObject s = str.substr(runtime, regs.beg[i], regs.end[i] - regs.beg[i]);
                if (taint) s.setTaint(true);
                if (block.yield(context, s).isTrue()) result.append(s);
            }
