Hi,
I know this is not a Java forum, but thought maybe somebody here with
Object Pascal and Java knowledge could help (seeing that Java-only
developers might not know what I'm talking about).
Does Java have an equivalent feature of a Object Pascal language's Class
Reference.
For Example:
I want to write Java code that does similar to my Object Pascal code
shown below:
TVisClassRef = class of TVisitor ;
procedure ExecuteVisitor(const pData: TVisited; const pVisClass:
TVisClassRef);
var
lVisitor: TVisitor;
begin
lVisitor := pVisClass.Create; // <<-- Important Part
try
pData.Iterate(lVisitor);
finally
lVisitor.Free;
end;
end;
This procedure takes care of the tedious business of creating the
visitor, calling iterate, then freeing the visitor when done. I can pass
in various class references as the second argument (all descendants of
TVisitor), and different class instances will be created and used as needed.
I would love to know how I could do this in Java.
Regards,
Graeme
