TRIO.BeforeDestruction Method
|
RAD Studio VCL Reference
|
|
|
Prevents the destruction of a TRIO instance if the reference count is greater than zero.
procedure BeforeDestruction; override;
virtual __fastcall BeforeDestruction();
BeforeDestruction is called automatically before the TRIO object's first destructor executes. Do not call it explicitly in your applications.
TRIO overrides the BeforeDestruction method to check the RefCount property. If RefCount is greater than zero, then there is still an outstanding reference to the TRIO object's interface,. and BeforeDestruction raises an exception to prevent the destruction of this object.
