List of all members.

Public Member Functions
	ExpressionEvaluatorJs ()
	Initializes a new JavaScript evaluator. This includes compiling the JavaScript code where evaluation is plugged in.
override void	RepairCommand (ref string command)
	Repairs the specified command and returns the repaired command string. Reparations serve for easier insertion of commands and for addition of syntactic cookies.
void	Register ()
	Registers the current object. Subsequent calls (after the first one) have no effect.
bool	IsRegistered ()
	Returns true if the current object is registered, false if not.
void	Unregister ()
	Unregisters the current object if it is currently registered. Can be performed several times, in this case only the first call may have effect.
Static Public Member Functions
static void	ExampleCommandLine ()
	Launches command-line JavaScript interpreter.
Protected Member Functions
override void	InitExpressionEvaluator ()
	Contains initializations for the particular class.

Properties
override string	ScriptBase [get]
	Container for compiled code that evaluates JavaScript expressions.
ObjectRegister < ExpressionEvaluatorJs >	ObjectRegister [get]

static ExpressionEvaluatorJs	Global [get, set]
	Global JavaScript expression evaluator. Initialized on first use.
Static Private Attributes

Member Function Documentation

override void IG::Lib::ExpressionEvaluatorJs::InitExpressionEvaluator

(

)

[inline, protected, virtual]

Contains initializations for the particular class.

This method is called form base class' constructor.

Implements IG::Lib::ExpressionEvaluatorCompiled.

override void IG::Lib::ExpressionEvaluatorJs::RepairCommand

(

ref string

command

)

[inline, virtual]

Repairs the specified command and returns the repaired command string. Reparations serve for easier insertion of commands and for addition of syntactic cookies.

Parameters:

command

Command to be repaired.

Reimplemented from IG::Lib::ExpressionEvaluatorCompiled.

void IG::Lib::ExpressionEvaluatorJs::Register

(

)

[inline]

Registers the current object. Subsequent calls (after the first one) have no effect.

Implements IG::Lib::IRegisterable< T >.

bool IG::Lib::ExpressionEvaluatorJs::IsRegistered

(

)

[inline]

Returns true if the current object is registered, false if not.

Returns:

Implements IG::Lib::IRegisterable< T >.

void IG::Lib::ExpressionEvaluatorJs::Unregister

(

)

[inline]

Unregisters the current object if it is currently registered. Can be performed several times, in this case only the first call may have effect.

Implements IG::Lib::IRegisterable< T >.

static void IG::Lib::ExpressionEvaluatorJs::ExampleCommandLine

(

)

[inline, static]

Launches command-line JavaScript interpreter.

Member Data Documentation

string IG::Lib::ExpressionEvaluatorJs::_baseDefinitionsJs [protected]

ObjectRegister<ExpressionEvaluatorJs> IG::Lib::ExpressionEvaluatorJs::_register [static, private]

Initial value:

            new ObjectRegister<ExpressionEvaluatorJs>(1 )

Static object that providees object register and generates IDs for this class:

ExpressionEvaluatorJs IG::Lib::ExpressionEvaluatorJs::_evaluatorGlobal = null [static, protected]

object IG::Lib::ExpressionEvaluatorJs::_globalLock = new object() [static, private]

---

Property Documentation

override string IG::Lib::ExpressionEvaluatorJs::ScriptBase [get, protected]

Container for compiled code that evaluates JavaScript expressions.

Reimplemented from IG::Lib::ExpressionEvaluatorCompiled.

ObjectRegister<ExpressionEvaluatorJs> IG::Lib::ExpressionEvaluatorJs::ObjectRegister [get]

Gets object register where the current object is registered.

Implements IG::Lib::IRegisterable< T >.

ExpressionEvaluatorJs IG::Lib::ExpressionEvaluatorJs::Global [static, get, set]

Global JavaScript expression evaluator. Initialized on first use.

In many applications you will not need more than one evaluator and you can just use this instance.
