Description
Disposed is a read-only property that shows the current state of this object.
The Disposed property returns True if the object has been disposed using the DisposeOf method. Otherwise, it returns False.
type
TMySimpleClass = class
private
//
stringMember: String;
constructor Create(Text: String);
destructor Destroy;
end;
constructor TMySimpleClass.Create(Text: String);
begin
stringMember := Text;
end;
destructor TMySimpleClass.Destroy;
begin
// this will be executed on calling the DisposeOf method.
end;
var
myObject: TMySimpleClass;
begin
myObject := TMySimpleClass.Create
('This is a code snippet illustrating the functionality for the DisposeOf method and Disposed property');
if not myObject.Disposed then
myObject.DisposeOf;
//Starting here, the object has entered the Disposed state.
end.
Note: The System.TObject.DisposeOf method is supported by the Delphi mobile compilers. The Disposed state only takes effect under compilers that use Automatic Reference Counting, such as DCCIOSARM.EXE, DCCIOSARM64.EXE, and DCCIOS32.EXE.
