Memory-managed wrapper type.

Type class for types which can be safely cast to Context, for instance with toContext.

Cast to Context, for types for which this is known to be safe. For general casts, use castTo.

Check the given code in context for syntax errors. The lineNumber is the starting line number in uri; the value is one-based so the first line is 1. uri and lineNumber are only used to fill the exception. In case of errors exception will be set to a new Exception with the details. You can pass Nothing to exception to ignore the error details.

Clear the uncaught exception in context if any.

Evaluate code in context.

Evaluate code and create an new object where symbols defined in code will be added as properties, instead of being added to context global object. The new object is returned as object parameter. Similar to how valueNewObject works, if objectInstance is not Nothing objectClass must be provided too. The lineNumber is the starting line number in uri; the value is one-based so the first line is 1. uri and lineNumber will be shown in exceptions and they don't affect the behavior of the script.

Evaluate code in context using uri as the source URI. The lineNumber is the starting line number in uri; the value is one-based so the first line is 1. uri and lineNumber will be shown in exceptions and they don't affect the behavior of the script.

Get the Context that is currently executing a function. This should only be called within a function or method callback, otherwise Nothing will be returned.

Get the last unhandled exception thrown in context by API functions calls.

Get a Value referencing the context global object

Get a property of context global object with name.

Get the VirtualMachine where context was created.

Create a new Context. The context is created in a new VirtualMachine. Use contextNewWithVirtualMachine to create a new Context in an existing VirtualMachine.

Create a new Context in virtualMachine.

Remove the last ExceptionHandler previously pushed to context with contextPushExceptionHandler.

Push an exception handler in context. Whenever a JavaScript exception happens in the Context, the given handler will be called. The default ExceptionHandler simply calls contextThrowException to throw the exception to the Context. If you don't want to catch the exception, but only get notified about it, call contextThrowException in handler like the default one does. The last exception handler pushed is the only one used by the Context, use contextPopExceptionHandler to remove it and set the previous one. When handler is removed from the context, destroyNotify i called with userData as parameter.

Register a custom class in context using the given name. If the new class inherits from another Class, the parent should be passed as parentClass, otherwise Nothing should be used. The optional vtable parameter allows to provide a custom implementation for handling the class, for example, to handle external properties not added to the prototype. When an instance of the Class is cleared in the context, destroyNotify is called with the instance as parameter.

Set a property of context global object with name and value.

Throw an exception to context using the given error message. The created Exception can be retrieved with contextGetException.

Throw exception to context.

Throw an exception to context using the given error name and message. The created Exception can be retrieved with contextGetException.

Construct a GValueConstruct with valid value for the “virtual-machine” property. This is rarely needed directly, but it is used by new.

Get the value of the “virtual-machine” property. When overloading is enabled, this is equivalent to

get context #virtualMachine
