Member Function Documentation

bool KJS::FunctionImp::getOwnPropertySlot	(	ExecState *	exec,
		const Identifier &	propertyName,
		PropertySlot &	slot
	)			`[virtual]`

Reimplemented from KJS::JSObject.

Definition at line 276 of file function.cpp.

void KJS::FunctionImp::put	(	ExecState *	exec,
		const Identifier &	propertyName,
		JSValue *	value,
		int	attr = `None`
	)			`[virtual]`

Sets the specified property.

See ECMA 8.6.2.2

Parameters:

	exec	The current execution state
	propertyName	The name of the property to set
	propertyValue	The value to set

Reimplemented from KJS::JSObject.

Definition at line 298 of file function.cpp.

bool KJS::FunctionImp::deleteProperty	(	ExecState *	exec,
		const Identifier &	propertyName
	)			`[virtual]`

Removes the specified property from the object.

See ECMA 8.6.2.5

Parameters:

	exec	The current execution state
	propertyName	The name of the property to delete

Returns:: true if the property was successfully deleted or did not exist on the object. false if deleting the specified property is not allowed.

Reimplemented from KJS::JSObject.

Definition at line 305 of file function.cpp.

JSValue * KJS::FunctionImp::callAsFunction	(	ExecState *	exec,
		JSObject *	thisObj,
		const List &	args
	)			`[virtual]`

Implements KJS::InternalFunctionImp.

Definition at line 110 of file function.cpp.

Identifier KJS::FunctionImp::getParameterName ( int index )

Definition at line 319 of file function.cpp.

virtual Completion KJS::FunctionImp::execute ( ExecState * exec ) [pure virtual]

Implemented in KJS::DeclaredFunctionImp.

virtual const ClassInfo* KJS::FunctionImp::classInfo ( ) const [inline, virtual]

A pointer to a ClassInfo struct for this class.

This provides a basic facility for run-time type information, and can be used to check an object's class an inheritance (see inherits()). This should always return a statically declared pointer, or 0 to indicate that there is no class information.

This is primarily useful if you have application-defined classes that you wish to check against for casting purposes.

For example, to specify the class info for classes FooImp and BarImp, where FooImp inherits from BarImp, you would add the following in your class declarations:

   class BarImp : public JSObject {
     virtual const ClassInfo *classInfo() const { return &info; }
     static const ClassInfo info;
     // ...
   };

   class FooImp : public JSObject {
     virtual const ClassInfo *classInfo() const { return &info; }
     static const ClassInfo info;
     // ...
   };

And in your source file:

   const ClassInfo BarImp::info = {"Bar", 0, 0, 0}; // no parent class
   const ClassInfo FooImp::info = {"Foo", &BarImp::info, 0, 0};

Reimplemented from KJS::InternalFunctionImp.

Reimplemented in KJS::DeclaredFunctionImp.

Definition at line 56 of file scriptfunction.h.

const ScopeChain& KJS::FunctionImp::scope ( ) const [inline]

Returns the scope of this object.

This is used when execution declared functions - the execution context for the function is initialized with extra object in it's scope. An example of this is functions declared inside other functions:

 function f() {

   function b() {
     return prototype;
   }

   var x = 4;
   // do some stuff
 }
 f.prototype = new String();

When the function f.b is executed, its scope will include properties of f. So in the example above the return value of f.b() would be the new String object that was assigned to f.prototype.

Parameters:

exec

The current execution state

Returns:: The function's scope

Definition at line 88 of file scriptfunction.h.

void KJS::FunctionImp::mark ( ) [virtual]

Reimplemented from KJS::JSObject.
