Class JRubyLibrary

java.lang.Object

org.jruby.ext.jruby.JRubyLibrary

All Implemented Interfaces:

Library

public class JRubyLibrary
extends java.lang.Object
implements Library

Native part of require 'jruby', e.g. provides methods for swapping between the normal Ruby reference to an object and the Java-integration-wrapped reference. Parts of JRuby name-space are loaded even without require 'jruby', those live under JRuby::Util.

Method Detail

load

public void load(Ruby runtime,
                 boolean wrap)

Specified by:

load in interface Library

reference

public static IRubyObject reference(ThreadContext context,
                                    IRubyObject recv,
                                    IRubyObject obj)

Wrap the given object as in Java integration and return the wrapper. This version uses ObjectProxyCache to guarantee the same wrapper is returned as long as it is in use somewhere.

reference0

public static IRubyObject reference0(ThreadContext context,
                                     IRubyObject recv,
                                     IRubyObject obj)

Wrap the given object as in Java integration and return the wrapper. This version does not use ObjectProxyCache.

runtime

public static IRubyObject runtime(ThreadContext context,
                                  IRubyObject recv)

dereference

public static IRubyObject dereference(ThreadContext context,
                                      IRubyObject recv,
                                      IRubyObject obj)

Unwrap the given Java-integration-wrapped object, returning the unwrapped object. If the wrapped object is not a Ruby object, an error will raise.

with_current_runtime_as_global

public static IRubyObject with_current_runtime_as_global(ThreadContext context,
                                                         IRubyObject recv,
                                                         Block block)

Run the provided (required) block with the "global runtime" set to the current runtime, for libraries that expect to operate against the global runtime.

set_context_class_loader

public static IRubyObject set_context_class_loader(ThreadContext context,
                                                   IRubyObject recv,
                                                   IRubyObject[] args)

is_security_restricted

public static RubyBoolean is_security_restricted(IRubyObject recv)

set_security_restricted

public static IRubyObject set_security_restricted(IRubyObject recv,
                                                  IRubyObject arg)

identity_hash

public static IRubyObject identity_hash(ThreadContext context,
                                        IRubyObject recv,
                                        IRubyObject obj)

Provide the "identity" hash code that System.identityHashCode would produce. Added here as an extension because calling System.identityHashCode (and other Java-integration-related mechanisms) will cause some core types to coerce to Java types, losing their proper identity.

parse

public static IRubyObject parse(ThreadContext context,
                                IRubyObject recv,
                                IRubyObject[] args,
                                Block block)

compile_ir

public static IRubyObject compile_ir(ThreadContext context,
                                     IRubyObject recv,
                                     IRubyObject[] args,
                                     Block block)

compile

public static IRubyObject compile(ThreadContext context,
                                  IRubyObject recv,
                                  IRubyObject[] args,
                                  Block block)

load_string_ext

@Deprecated
public static IRubyObject load_string_ext(ThreadContext context,
                                                      IRubyObject recv)

Deprecated.

subclasses

public static IRubyObject subclasses(ThreadContext context,
                                     IRubyObject recv,
                                     IRubyObject arg)

                                     IRubyObject recv,
