ScriptingContainer provides various methods and resources that are useful for embedding Ruby in Java. Using this class, users can run Ruby scripts from Java programs easily. Also, users can use methods defined or implemented by Ruby. ScriptingContainer allows users to set various configuration parameters. Some of them are per-container properties, while others are per-evaluation attributes. For example, a local context scope, local variable behavior, load paths are per-container properties. Please see PropertyName and AttributeName for more details. Be aware that the per-container properties should be set prior to get Ruby runtime being instantiated; otherwise, default values are applied to. ScriptingContainer delays Ruby runtime initialization as much as possible to improve startup time. When values are put into the ScriptingContainer, or runScriptlet method gets run the runtime is created internally. However, the default, singleton local context scope behave slightly different. If a Ruby runtime has been already instantiated by another ScriptingContainer, application, etc, the same runtime will be re-used. Below are examples. The first Example is a very simple Hello World. After initializing a ScriptingContainer, a Ruby script, puts "Hello World!", runs and produces "Hello World!." Example 1: 
    ScriptingContainer container = new ScriptingContainer();
    container.runScriptlet("puts \"Hello World!\"");
 Produces: Hello World! 
 The second example shows how to share variables between Java and Ruby. In this example, a local variable "x" is shared. To make this happen, a local variable behavior should be transient or persistent. As for JSR223 JRuby engine, set these types using a System property, org.jruby.embed.localvariable.behavior. If the local variable behavior is one of transient or persistent, Ruby's local, instance, global variables and constants are available to share between Java and Ruby. (A class variable sharing does not work on current version) Thus, "x" in Java is also "x" in Ruby. Example 2: 
    ScriptingContainer container = new ScriptingContainer();
    container.put("x", 12345);
    container.runScriptlet("puts x.to_s(2)");
 Produces: 11000000111001 
The third examples shows how to keep local variables across multiple evaluations.
This feature simulates BSF engine for JRuby. In terms of Ruby semantics,
local variables should not survive after the evaluation has completed. Thus,
this behavior is optional, and users need to specify LocalVariableBehavior.PERSISTENT
when the container is instantiated.
Example 3: 
    ScriptingContainer container = new ScriptingContainer(LocalVariableBehavior.PERSISTENT);
    container.runScriptlet("p=9.0");
    container.runScriptlet("q = Math.sqrt p");
    container.runScriptlet("puts \"square root of #{p} is #{q}\"");
    System.out.println("Ruby used values: p = " + container.get("p") + ", q = " + container.get("q"));
 Produces: square root of 9.0 is 3.0 Ruby used values: p = 9.0, q = 3.0 
Also, ScriptingContainer provides better i18n support. For example,
Unicode Escape Sequence can be included in Ruby scripts.
In addition, ScriptingContainer supports a parse-once-eval-many-times feature,
invoking methods defined by Ruby, and getting an instance of a specified interface
that has been implemented by Ruby.
Example 4: 
    ScriptingContainer container = new ScriptingContainer();
    String script =
      "def message\n" +
        "\"message: #{@message}\"\n" +
      "end\n" +
      "message";
    container.put("@message", "What's up?");
    JavaEmbedUtils.EvalUnit unit = container.parse(script);
    IRubyObject msg = unit.run(); // a RubyString instance
    System.out.println(JavaEmbedUtils.rubyToJava(msg));
    container.put("@message", "Fabulous!");
    msg = unit.run();
    System.out.println(JavaEmbedUtils.rubyToJava(msg));
    container.put("@message", "That's the way you are.");
    msg = unit.run();
    System.out.println(JavaEmbedUtils.rubyToJava(msg));
 Produces: message: What's up? message: Fabulous! message: That's the way you are.

implemented by Ruby.
