本文整理了Java中org.jruby.RubyClass.newClass方法的一些代码示例，展示了RubyClass.newClass的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。RubyClass.newClass方法的具体详情如下：
包路径：org.jruby.RubyClass
类名称：RubyClass
方法名：newClass

RubyClass.newClass介绍

[英]Construct a new class with the given name scoped under Object (global) and with Object as its immediate superclass. Corresponds to rb_class_new in MRI.
[中]构造一个新类，其给定名称的作用域位于Object（全局）下，对象作为其直接超类。对应于核磁共振成像中的rb_类_新。

代码示例

private RubyModule buildClassFromDescriptor(ThreadContext context) {
  Ruby runtime = context.runtime;
  ObjectAllocator allocator = new ObjectAllocator() {
    @Override
    public IRubyObject allocate(Ruby runtime, RubyClass klazz) {
      return new RubyMessage(runtime, klazz, descriptor);
    }
  };
  // rb_define_class_id
  RubyClass klass = RubyClass.newClass(runtime, runtime.getObject());
  klass.setAllocator(allocator);
  klass.makeMetaClass(runtime.getObject().getMetaClass());
  klass.inherit(runtime.getObject());
  RubyModule messageExts = runtime.getClassFromPath("Google::Protobuf::MessageExts");
  klass.include(new IRubyObject[] {messageExts});
  klass.instance_variable_set(runtime.newString(Utils.DESCRIPTOR_INSTANCE_VAR), this);
  klass.defineAnnotatedMethods(RubyMessage.class);
  return klass;
}
