```
public final class Ruby
extends Object
```
The Ruby object represents the top-level of a JRuby "instance" in a given VM. JRuby supports spawning multiple instances in the same JVM. Generally, objects created under these instances are tied to a given runtime, for such details as identity and type, because multiple Ruby instances means there are multiple instances of each class. This means that in multi-runtime mode (or really, multi-VM mode, where each JRuby instance is a ruby "VM"), objects generally can't be transported across runtimes without marshaling. This class roots everything that makes the JRuby runtime function, and provides a number of utility methods for constructing global types and accessing global runtime structures.

newInstance
```
public static Ruby newInstance(InputStream in,
               PrintStream out,
               PrintStream err)
```
Returns a new instance of the JRuby runtime configured with the given input, output and error streams and otherwise default configuration (except where specified system properties alter defaults).

Parameters:
in - the custom input stream
out - the custom output stream
err - the custom error stream

Returns:
the JRuby runtime
See Also:
RubyInstanceConfig

isGlobalRuntimeReady
```
public static boolean isGlobalRuntimeReady()
```
Tests whether globalRuntime has been instantiated or not. This method is used by singleton model of org.jruby.embed.ScriptingContainer to decide what RubyInstanceConfig should be used. When a global runtime is not there, RubyInstanceConfig of AbstractContextProvider will be used to enact configurations set by a user. When a global runtime is already instantiated, RubyInstanceConfig of the global runtime should be used in ScriptingContaiener.

Returns:
true if a global runtime is instantiated, false for other.

getGlobalRuntime
```
public static Ruby getGlobalRuntime()
```
Get the global runtime.

Returns:
the global runtime

useAsGlobalRuntime
```
public void useAsGlobalRuntime()
```
Convenience method for java integrators who may need to switch the notion of "global" runtime. Use JRuby.runtime.use_as_global_runtime from Ruby code to activate the current runtime as the global one.

clearGlobalRuntime
```
public static void clearGlobalRuntime()
```
Clear the global runtime.

getThreadLocalRuntime
```
public static Ruby getThreadLocalRuntime()
```
Get the thread-local runtime for the current thread, or null if unset.

Returns:
the thread-local runtime, or null if unset

setThreadLocalRuntime
```
public static void setThreadLocalRuntime(Ruby ruby)
```
Set the thread-local runtime to the given runtime. Note that static threadlocals like this one can leak resources across (for example) application redeploys. If you use this, it is your responsibility to clean it up appropriately.

Parameters:
ruby - the new runtime for thread-local

evalScriptlet
```
public IRubyObject evalScriptlet(String script)
```
Evaluates a script under the current scope (perhaps the top-level scope) and returns the result (generally the last value calculated). This version goes straight into the interpreter, bypassing compilation and runtime preparation typical to normal script runs.

Parameters:
script - The scriptlet to run

evalScriptlet
```
public IRubyObject evalScriptlet(String script,
                        DynamicScope scope)
```
Evaluates a script under the current scope (perhaps the top-level scope) and returns the result (generally the last value calculated). This version goes straight into the interpreter, bypassing compilation and runtime preparation typical to normal script runs. This version accepts a scope to use, so you can eval many times against the same scope.

Parameters:
script - The scriptlet to run
scope - The scope to execute against (ManyVarsDynamicScope is recommended, so it can grow as needed)

executeScript
```
public IRubyObject executeScript(String script,
                        String filename)
```
Parse and execute the specified script This differs from the other methods in that it accepts a string-based script and parses and runs it as though it were loaded at a command-line. This is the preferred way to start up a new script when calling directly into the Ruby object (which is generally *dis*couraged.

Parameters:
script - The contents of the script to run as a normal, root script

Returns:
The last value of the script

runFromMain
```
public void runFromMain(InputStream inputStream,
               String filename)
```
Run the script contained in the specified input stream, using the specified filename as the name of the script being executed. The stream will be read fully before being parsed and executed. The given filename will be used for the ruby $PROGRAM_NAME and $0 global variables in this runtime. This method is intended to be called once per runtime, generally from Main or from main-like top-level entry points. As part of executing the script loaded from the input stream, various RubyInstanceConfig properties will be used to determine whether to compile the script before execution or run with various wrappers (for looping, printing, and so on, see jruby -help).

Parameters:
inputStream - The InputStream from which to read the script contents
filename - The filename to use when parsing, and for $PROGRAM_NAME and $0 ruby global variables.

parseFromMain
```
public Node parseFromMain(InputStream inputStream,
                 String filename)
```
Parse the script contained in the given input stream, using the given filename as the name of the script, and return the root Node. This is used to verify that the script syntax is valid, for jruby -c. The current scope (generally the top-level scope) is used as the parent scope for parsing.

Parameters:
inputStream - The input stream from which to read the script
filename - The filename to use for parsing

Parameters:
node - The node to attempt to compiled
inspector - The ASTInspector to use for making optimization decisions

Returns:
an instance of the successfully-compiled Script, or null.

Faster than newSymbol(String) if you already have an interned name String. Don't intern your string just to call this version - the overhead of interning will more than wipe out any benefit from the faster lookup.

Parameters:

Returns:
the symbol for name

Parameters:: exceptionClass -; message -
Returns:

newLightweightStopIterationError
```
public RaiseException newLightweightStopIterationError(String message)
```
Generate a StopIteration exception. This differs from the normal logic by avoiding the generation of a backtrace. StopIteration is used by Enumerator to end an external iteration, and so generating a full backtrace is usually unreasonable overhead. The flag -Xstop_iteration.backtrace=true or the property jruby.stop_iteration.backtrace=true forces all StopIteration exceptions to generate a backtrace.

Parameters:
message - the message for the exception

execRecursive
```
public IRubyObject execRecursive(Ruby.RecursiveFunction func,
                        IRubyObject obj)
```
Perform a recursive walk on the given object using the given function. Do not call this method directly unless you know you're within a call to recursiveListOperation, which will ensure the thread-local recursion tracking data structs are cleared. MRI: rb_exec_recursive Calls func(obj, arg, recursive), where recursive is non-zero if the current method is called recursively on obj

Parameters:
func -
obj -

Returns:

execRecursiveOuter
```
public IRubyObject execRecursiveOuter(Ruby.RecursiveFunction func,
                             IRubyObject obj)
```
Perform a recursive walk on the given object using the given function. Treat this as the outermost call, cleaning up recursive structures. MRI: rb_exec_recursive_outer If recursion is detected on the current method and obj, the outermost func will be called with (obj, arg, Qtrue). All inner func will be short-circuited using throw.

Parameters:
func -
obj -

Returns:

recursiveListOperation
```
public <T extends IRubyObject> T recursiveListOperation(Callable<T> body)
```
Begin a recursive walk that may make one or more calls to execRecursive. Clean up recursive structures once complete.

Type Parameters:
