330 // an Any. Then the type info does not tell what the type of the value, that is kept

334 // the JScript value objects within a JScript script on such an occasion.

338 // A JScriptValue (ValueObject) object is a COM object in that it implements IDispatch and the
339 // IJScriptValue object interface. Such objects are provided by all UNO wrapper
340 // objects used within a JScript script. To obtain an instance one has to call
341 // "_GetValueObject() or Bridge_GetValueObject()" on an UNO wrapper object (class InterfaceOleWrapper_Impl).
342 // A value object is appropriately initialized within the script and passed as
343 // parameter to an UNO object method or property. The convertDispparamsArgs function
344 // can easily find out that a param is such an object by queriing for the
345 // IJScriptValue interface. By this interface one the type and kind ( out, in/out)
346 // can be determined and the right conversion can be applied.
347 // Using ValueObjects we spare us the effort of acquiring and examining type information
348 // in order to figure out what the an IDispatch parameter is meant for.
349
350 // Normal JScript object parameter can be mixed with JScriptValue object. If an
351 // VARIANT contains an VT_DISPATCH that is no JScriptValue than the type information
352 // is used to find out about the reqired type.
