ios_base::event

  • Artykuł

Specifies event types.

enum event {erase_event, imbue_event, copyfmt_event};

Remarks

The type is an enumerated type that describes an object that can store the callback event used as an argument to a function registered with register_callback. The distinct event values are:

  • copyfmt_event, to identify a callback that occurs near the end of a call to copyfmt, just before the exception mask is copied.

  • erase_event, to identify a callback that occurs at the beginning of a call to copyfmt, or at the beginning of a call to the destructor for *this.

  • imbue_event, to identify a callback that occurs at the end of a call to imbue, just before the function returns.

Example

See register_callback for an example.
