线程中的override有什么作用的?
例如:
protected
procedure Execute;
override;
public
constructor Create(Suspended:Boolean;Query:TAdoQuery;DS:TDataSource);
{ 线程构造器 }
destructor Destroy;override;
///////////////
public
constructor Create(CreateSuspended: Boolean;
aFileName,{文件名} aTbName:{表名} string;
aConn: TADOConnection);
overload;
destructor Destroy;
override;
在很多的例子中,都有override,第二代源码中,还用到overload,起到什么的作用?
