Hi,
I haven't used type helpers but why not change to defines like
type
jObjectRec = record end;
jObject= ^jObjectRec;
jClassRec = record end;
jClass = ^jClassRec;
or possibly simpler you could try
jclass = type(jobject); // I believe this forces a new type and is
not just an alias
that looks better.
Who can change them? These jobject/jclass type definitions are part of
fpc...
Although type is weird
type a = type (pointer);
type b = type (a);
does not compile, duplicate identifier a
type a = type (pointer);
type b = type a;
compiles, but a type helper for cannot use self as pointer. self <> nil
=> operator is not overloaded. But you can do writeln(self);
type a = type pointer;
type b = type (a);
does not compile, duplicate identifier a
type a = type pointer;
type b = type a;
compiles, and is like a pointer, but unlike case 2, you cannot do
writeln(self) in the type helper
type a = type (pointer);
type b = type (pointer);
does not compile, duplicate identifier
type a = type (pointer);
type b = type pointer;
does not compile, error in type definition
type a = type pointer;
type b = type (pointer);
compiles
type a = type pointer;
type b = type pointer;
compiles
Cheers,
Benito

But this does not work, because fpc thinks jclass and jobject are the
same type, so there is only one type helper for both of the types
allowed.
Because it is declared as
type
jobject=pointer;
jclass=jobject;
What can we do about this?
