The Parent keyword is used with the namespace operator (::) to reference the previous definition of a function that has been overridden either through inheritance or packaging. The Parent keyword can only be used within specific contexts:
- From within a consoleMethod, or
- from within a packaged function.
//Calling an inherited parent
datablock ItemData( GoldCoin )
{

};
function ItemData::onAdd( %db, %obj )
{
echo( "ItemData::onAdd()" );
}
function GoldCoin::onAdd( %db, %obj )
{
Parent::onAdd( %db, %obj );
echo( "GoldCoin::onAdd()" );
}
//Calling a parent
function testFunction()
{
echo( "testFunction() - unpackaged." );
}
MyPackage0
{

echo( "testFunction() - MyPackage0." );

};
...
testFunction();
//prints => testFunction() - unpackaged.
ActivatePackage( MyPackage0 );
testFunction();
// prints => testFunction() - unpackaged.
// prints => testFunction() - MyPackage0.
