Where a unit exports an instance of an object, what's best practice for
making this read-only? I'm referring to the object reference itself
here, not properties of the object.
Where I've done this in the past I've used a function:
interface
function InitText: TFormattedString;
implementation
var xInitText: TFormattedString= nil;
function InitText: TFormattedString;
begin
result := xInitText
end { InitText } ;
Is there a better way using e.g. global properties that doesn't
necessitate both a property and an explicit function?
property InitText: TFormattedString read xInitText;
The obvious problem here is that xInitText is a forward reference to an
unexported variable.
