[英]Jruby “RuntimeHelpers” class is deprecated
I am having a project based on JRuby on rails, now I am migrating this project to jruby-9.0.5.0 version. 我有一个基于JRuby的项目,现在我正在将该项目迁移到jruby-9.0.5.0版本。
In the code, ruby is called from Java file as shown below: 在代码中,从Java文件调用ruby,如下所示:
String source = new StringBuilder("require 'java'\n" +
"\n" +
"java_package 'jrubysource'\n" +
"class SystemFilePath\n" +
" attr_accessor :topDirCmd, :topDirNames\n" +
" java_signature 'SystemFilePath(String topDirCmd)'\n" +
" def initialize(topDirCmd)\n" +
" @topDirCmd = topDirCmd\n" +
" setTopDirectoryNames()\n" +
" end\n" +
"\n" +
" java_signature 'void setTopDirectoryNames()'\n" +
" def setTopDirectoryNames\n" +
" Open3.popen3(@topDirCmd) { |stdin, stdout, stderr, wait_thread|\n" +
" out = stdout.read\n" +
" err = stderr.read\n" +
" if err.size > 0 || out.size == 0\n" +
" @topDirNames = nil\n" +
" return\n" +
" end\n" +
" out = out.split(/\\n/).select{|a| a.match(/system_1/) && !a.match(/system_1\\/sim/)}.join(\"\\n\") + \"\\n\";\n" +
" topDirNames = out.split(/\\//).select{|a| a.match(/\\n$/) }.map(&:chomp)\n" +
" if topDirNames.size == 0 then\n" +
" @topDirNames = nil\n" +
" return\n" +
" end\n" +
" @topDirNames = topDirNames.sort.reverse\n" +
" }\n" +
" rescue Exception => e\n" +
" @topDirNames = nil\n" +
" end\n" +
"\n" +
"end\n" +
"").toString();
__ruby__.executeScript(source, "system_file_path.rb");
RubyClass metaclass = __ruby__.getClass("SystemFilePath");
metaclass.setRubyStaticAllocator(SystemFilePath.class);
if (metaclass == null) throw new NoClassDefFoundError("Could not load Ruby class: SystemFilePath");
__metaclass__ = metaclass;
}
public void setTopDirectoryNames() {
@SuppressWarnings("unused")
IRubyObject ruby_result = RuntimeHelpers.invoke(__ruby__.getCurrentContext(), this, "setTopDirectoryNames"); //Here i am calling ruby code from java file.
return;
}
Now, according to a JRuby API document "RuntimeHelpers" class is deprecated. 现在,根据JRuby API文档, “ RuntimeHelpers”类已弃用。
The document provides no alternative API. 该文档没有提供其他API。 Please guide me towards an alternative as this is a blocker for me.
请引导我寻求其他选择,因为这对我来说是一个障碍。
its an internal JRuby API ... you have a similar API available for every IRubyObject : 它是一个内部JRuby API ...您可以为每个IRubyObject使用类似的API:
instead of 代替
RuntimeHelpers.invoke(__ruby__.getCurrentContext(), this, "setTopDirectoryNames")
try : 尝试:
this.callMethod(__ruby__.getCurrentContext(), "setTopDirectoryNames")
