| * An object reference managed by the v8 garbage collector. |

| * because the garbage collector may move objects, it is unsafe to |
| * point directly to an object. Instead, all objects are stored in |

| * whenever an object moves. Handles should always be passed by value |
| * (except in cases like out-parameters) and they should never be |
| * allocated on the heap. |
| * |
| * There are two types of handles: local and persistent handles. |
| * Local handles are light-weight and transient and typically used in |
| * local operations. They are managed by HandleScopes. Persistent |
| * handles can be used when storing objects across several independent |
| * operations and have to be explicitly deallocated when they're no |
| * longer used. |
| * |
| * It is safe to extract the object stored in the handle by |
| * dereferencing the handle (for instance, to extract the Object* from |
| * an Handle<Object>); the value will still be governed by a handle |
| * behind the scenes and the same rules apply to these values as to |

| * A FunctionTemplate is used to create functions at runtime. There |
| * can only be one function created from a FunctionTemplate in a |
| * context. |
| * |
| * A FunctionTemplate can have properties, these properties are added to the |
| * function object when it is created. |
| * |
| * A FunctionTemplate has a corresponding instance template which is |
| * used to create object instances when the function is used as a |
| * constructor. Properties added to the instance template are added to |
| * each object instance. |
| * |
| * A FunctionTemplate can have a prototype template. The prototype template |
| * is used to create the prototype object of the function. |
| * |
| * The following example shows how to use a FunctionTemplate: |
| * |
| * \code |
| * v8::Local<v8::FunctionTemplate> t = v8::FunctionTemplate::New(); |
| * t->Set("func_property", v8::Number::New(1)); |
| * |
| * v8::Local<v8::Template> proto_t = t->PrototypeTemplate(); |
| * proto_t->Set("proto_method", v8::FunctionTemplate::New(InvokeCallback)); |
| * proto_t->Set("proto_const", v8::Number::New(2)); |
| * |
| * v8::Local<v8::ObjectTemplate> instance_t = t->InstanceTemplate(); |
| * instance_t->SetAccessor("instance_accessor", InstanceAccessorCallback); |
| * instance_t->SetNamedPropertyHandler(PropertyHandlerCallback, ...); |
| * instance_t->Set("instance_property", Number::New(3)); |
| * |
| * v8::Local<v8::Function> function = t->GetFunction(); |
| * v8::Local<v8::Object> instance = function->NewInstance(); |
| * \endcode |
| * |
| * Let's use "function" as the JS variable name of the function object |
| * and "instance" for the instance object created above. The function |
| * and the instance will have the following properties: |
| * |
| * \code |
| * func_property in function == true; |
| * function.func_property == 1; |
| * |
| * function.prototype.proto_method() invokes 'InvokeCallback' |
| * function.prototype.proto_const == 2; |
| * |
| * instance instanceof function == true; |
| * instance.instance_accessor calls 'InstanceAccessorCallback' |
| * instance.instance_property == 3; |
| * \endcode |
| * |
| * A FunctionTemplate can inherit from another one by calling the |
| * FunctionTemplate::Inherit method. The following graph illustrates |
| * the semantics of inheritance: |
| * |
| * \code |
| * FunctionTemplate Parent -> Parent() . prototype -> { } |
| * ^ ^ |
| * | Inherit(Parent) | .__proto__ |
| * | | |
| * FunctionTemplate Child -> Child() . prototype -> { } |
| * \endcode |
| * |
| * A FunctionTemplate 'Child' inherits from 'Parent', the prototype |
| * object of the Child() function has __proto__ pointing to the |
| * Parent() function's prototype object. An instance of the Child |
| * function has all properties on Parent's instance templates. |
| * |
| * Let Parent be the FunctionTemplate initialized in the previous |
| * section and create a Child FunctionTemplate by: |
| * |
| * \code |
| * Local<FunctionTemplate> parent = t; |
| * Local<FunctionTemplate> child = FunctionTemplate::New(); |
| * child->Inherit(parent); |
| * |
| * Local<Function> child_function = child->GetFunction(); |
| * Local<Object> child_instance = child_function->NewInstance(); |
| * \endcode |
| * |
| * The Child function and Child instance will have the following |
| * properties: |
| * |
| * \code |
| * child_func.prototype.__proto__ == function.prototype; |
| * child_instance.instance_accessor calls 'InstanceAccessorCallback' |
| * child_instance.instance_property == 3; |

| * Multiple threads in V8 are allowed, but only one thread at a time |

| * accessing handles or holding onto object pointers obtained from V8 |
| * handles. It is up to the user of V8 to ensure (perhaps with |
| * locking) that this constraint is not violated. |
| * |
| * If you wish to start using V8 in a thread you can do this by constructing |
| * a v8::Locker object. After the code using V8 has completed for the |
| * current thread you can call the destructor. This can be combined |
| * with C++ scope-based construction as follows: |
| * |
| * \code |
| * ... |
| * { |
| * v8::Locker locker; |
| * ... |
| * // Code using V8 goes here. |
| * ... |
| * } // Destructor called here |
| * \endcode |
| * |
| * If you wish to stop using V8 in a thread A you can do this by either |
| * by destroying the v8::Locker object as above or by constructing a |
| * v8::Unlocker object: |
| * |
| * \code |
| * { |
| * v8::Unlocker unlocker; |
| * ... |
| * // Code not using V8 goes here while V8 can run in another thread. |
| * ... |
| * } // Destructor called here. |
| * \endcode |
| * |
| * The Unlocker object is intended for use in a long-running callback |
| * from V8, where you want to release the V8 lock for other threads to |
| * use. |
| * |
| * The v8::Locker is a recursive lock. That is, you can lock more than |
| * once in a given thread. This can be useful if you have code that can |
| * be called either from code that holds the lock or from code that does |
| * not. The Unlocker is not recursive so you can not have several |
| * Unlockers on the stack at once, and you can not use an Unlocker in a |
| * thread that is not inside a Locker's scope. |
| * |
| * An unlocker will unlock several lockers if it has to and reinstate |
| * the correct depth of locking on its destruction. eg.: |
| * |
| * \code |
| * // V8 not locked. |
| * { |
| * v8::Locker locker; |
| * // V8 locked. |
| * { |
| * v8::Locker another_locker; |
| * // V8 still locked (2 levels). |
| * { |
| * v8::Unlocker unlocker; |
| * // V8 not locked. |
| * } |
| * // V8 locked again (2 levels). |
| * } |
