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 be 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 Ruby runtime is created internally. However, the default, singleton local context scope behave slightly different. If Ruby runtime has been already instantiated by another ScriptingContainer, application, etc, the same runtime will be 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 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();
         script =
          "def message\n" +
              "\"message: #\"\n" +
          "end\n" +
          "message";
         container.put("@message", "What's up?");
         EvalUnit unit = container.parse(script);
         IRubyObject ret = unit.run();
         System.out.println(JavaEmbedUtils.rubyToJava(ret));
         container.put("@message", "Fabulous!");
         ret = unit.run();
         System.out.println(JavaEmbedUtils.rubyToJava(ret));
         container.put("@message", "That's the way you are.");
         ret = unit.run();
         System.out.println(JavaEmbedUtils.rubyToJava(ret));
 
 Produces:
     message: What's up?
     message: Fabulous!
     message: That's the way you are.

Associates the specified value with the specified key in a variable map. This key-value pair is injected to a top level of runtime during evaluation. If the map previously contained a mapping for the key, the old value is replaced. The key must be a valid Ruby variable or constant name. It will be a top level variable or constant.

Parameters:
key is a key that the specified value is to be associated with
value is a value to be associated with the specified key
Returns:

Associates the specified value with the specified key in a variable map. This key-value pair is injected to a given receiver during evaluation. If the map previously contained a mapping for the key, the old value is replaced. The key must be a valid Ruby variable or constant name. A given receiver limits the scope of a variable or constant. However, a global variable is accessible globally always.

Parameters:
receiver a receiver to put the value in
key is a key that the specified value is to be associated with
value is a value to be associated with the specified key
Returns:
a previous value associated with a key, or null if there was no mapping for this key.

Returns:
a previous value associated with a key, or null if there was no mapping for this key.
    public Object remove(String key) {
        return .getVarMap().remove(key);
    }

    
Removes the specified Ruby variable with the specified variable name in a variable map and given receiver. If the map previously contained a mapping for the key, the old value is returned.

Parameters:
receiver a receiver to remove the value from
key is a key that the specified value is to be associated with
Returns:
a previous value associated with a key, or null if there was no mapping for this key.
    public Object remove(Object receiverString key) {
        return .getVarMap().remove(receiverkey);
    }

    
Removes all of the mappings from this map. The map will be empty after this call returns. Ruby variables are also removed from Ruby instance. However, Ruby instance keep having global variable names with null value. This is a short cut method of ScriptingContainer#getVarMap().clear().
    public void clear() {
        .getVarMap().clear();
    }

Example
 Interface
     //QuadraticFormula.java
     package org.jruby.embed;
     import java.util.List;
     public interface QuadraticFormula {
         List solve(int a, int b, int c) throws Exception;
     }

 Implementation
     #quadratic_formula.rb
     def solve(a, b, c)
       v = b ** 2 - 4 * a * c
       if v < 0: raise RangeError end
       s0 = ((-1)*b - Math.sqrt(v))/(2*a)
       s1 = ((-1)*b + Math.sqrt(v))/(2*a)
       return s0, s1
     end

 Usage
     ScriptingContainer container = new ScriptingContainer();
     String filename = "ruby/quadratic_formula_class.rb";
     Object receiver = container.runScriptlet(PathType.CLASSPATH, filename);
     QuadraticFormula qf = container.getInstance(receiver, QuadraticFormula.class);
     try {
          List<Double> solutions = qf.solve(1, -2, -13);
          printSolutions(solutions);
          solutions = qf.solve(1, -2, 13);
          for (double s : solutions) {
              System.out.print(s + ", ");
          }
     } catch (Exception e) {
          e.printStackTrace();

Returns an error output stream that Ruby runtime has. The stream is set when Ruby runtime is initialized.

Deprecated:

Returns:
an error output stream that Ruby runtime has
    public PrintStream getErr() {
        return getError();
    }

    
Cleanly shut down this ScriptingContainer and any JRuby resources it holds. All ScriptingContainer instances should be terminated when you are done with them, rather then leaving them for GC to finalize.

Since:
JRuby 1.5.0
    public void terminate() {
        if (getProvider().isRuntimeInitialized()) getProvider().getRuntime().tearDown(false);
        getProvider().terminate();
    }

    
Ensure this ScriptingContainer instance is terminated when nobody holds any references to it (and GC wants to reclaim it).

Throws:
java.lang.Throwable
Since:
JRuby 1.6.0
    public void finalize() throws Throwable {
        super.finalize();
        terminate();
    }
