Delphi Compiler Error
E2602 Procedure DISPOSE needs destructor identifier of ‘%s’, but undeclared identifier ‘%s’ found
Reason for the Error & Solution
This error message is issued when an identifier in the parameter list given to Dispose is not a destructor.
type
PObj = ^TObj;
TObj = object
FData: Integer;
destructor Finalize;
end;
var
R: PObj;
destructor TObj.Finalize;
begin
end;
begin
Dispose(R, Foo); // issues error: E2602
end.
The solution is to either pass a destructor to Dispose, or to eliminate the second argument.
type
PObj = ^TObj;
TObj = object
FData: Integer;
destructor Finalize;
end;
var
R: PObj;
destructor TObj.Finalize;
begin
end;
begin
Dispose(R, Finalize); // ok
end.
