IROPooledClassFactory

Overview

The IROPooledClassFactory interface is designed to clear the pool of the TROPooledClassFactory instance.

The following example demonstrates the usage of this interface:

var
  list: IROStrings;
  i: integer;
  cf: IROClassFactory;
  pcf: IROPooledClassFactory;
begin
  list := GetClassFactoryNames;
  for i := 0 to list.Count -1 do begin
    cf := GetClassFactory(list[i]);
    if Supports(cf,IROPooledClassFactory, pcf) then pcf.ClearPool;
    pcf := nil;
    cf := nil; 
  end;   
  list := nil;
