Constructor & Destructor Documentation

JsObject	(	const char *	name = "Object",
		Mutex *	mtx = 0,
		bool	frozen = false
	)

Constructor

Parameters:

name	Name of the object
mtx	Pointer to the mutex that serializes this object
frozen	True if the object is to be frozen from creation

virtual ~JsObject

[virtual]

Destructor

Member Function Documentation

void freeze

(

)

[inline]

Freeze the Javascript object preventing external changes to it

bool frozen

(

)

const [inline]

Retrieve the object frozen status (cannot modify attributes or methods)

Returns:

True if the object is frozen

static void initialize

(

ScriptContext *

context

)

[static]

Initialize the standard global objects in a context

Parameters:

context

Script context to initialize

virtual Mutex* mutex

(

)

[inline, virtual]

Retrieve the Mutex object used to serialize object access

Returns:

Pointer to the mutex of the context this object belongs to

Implements ScriptContext.

virtual ExpOperation* popValue	(	ObjList &	stack,
		GenObject *	context = 0
	)		[virtual]

Pops and evaluate the value of an operand off an evaluation stack, does not pop a barrier

Parameters:

stack	Evaluation stack to remove the operand from
context	Pointer to arbitrary object to be passed to called methods

Returns:

Value removed from stack, NULL if stack underflow or field not evaluable

virtual bool runAssign	(	ObjList &	stack,
		const ExpOperation &	oper,
		GenObject *	context
	)		[virtual]

Try to assign a value to a single field if object is not frozen

Parameters:

stack	Evaluation stack in use
oper	Field to assign to, contains the field name and new value
context	Pointer to arbitrary object passed from evaluation methods

Returns:

True if assignment succeeded

Reimplemented from ScriptContext.

virtual bool runField	(	ObjList &	stack,
		const ExpOperation &	oper,
		GenObject *	context
	)		[virtual]

Try to evaluate a single field

Parameters:

stack	Evaluation stack in use, field value must be pushed on it
oper	Field to evaluate
context	Pointer to arbitrary object passed from evaluation methods

Returns:

True if evaluation succeeded

Reimplemented from ScriptContext.

virtual bool runFunction	(	ObjList &	stack,
		const ExpOperation &	oper,
		GenObject *	context
	)		[virtual]

Try to evaluate a single method

Parameters:

stack	Evaluation stack in use, parameters are popped off this stack and results are pushed back on stack
oper	Function to evaluate
context	Pointer to arbitrary object passed from evaluation methods

Returns:

True if evaluation succeeded

Reimplemented from ScriptContext.

virtual bool runNative	(	ObjList &	stack,
		const ExpOperation &	oper,
		GenObject *	context
	)		[protected, virtual]

Try to evaluate a single native method

Parameters:

stack	Evaluation stack in use, parameters are popped off this stack and results are pushed back on stack
oper	Function to evaluate
context	Pointer to arbitrary object passed from evaluation methods

Returns:

True if evaluation succeeded
