Class TMessage

Unit

BaseMsg

Declaration

type TMessage = class(TObject)

Description

Base class for all message classes

Messages are stored in specific pool (see TMessagePool) to speed-up allocation and avoid memory leaks.
As a consequence, messages can be created in such way: SomeObject.HandleMessage(TMessage.Create) without risk of a memory leak.
Restriction: do not use in messages classes fields of types which needs finalization (such as dynamic arrays or long strings). Use short strings instead.
