-
inline bool operator==(const event_impl &e) const#
Compares this event with another event for equality based on their unique identifiers.
- Parameters:
e – The event to compare with.
- Returns:
True if the events have the same unique identifier, false otherwise.
-
inline bool operator<(const event_impl &e) const#
Compares this event with another event for ordering based on their unique identifiers.
- Parameters:
e – The event to compare with.
- Returns:
True if this event’s unique identifier is less than the other event’s identifier, false otherwise.
- inline void set_symbol_with_dot(
- reserved::per_ctx_dot &dot,
- ::std::string s,
Sets a symbolic name for the event, useful for debugging or tracing.
- Parameters:
s – The symbolic name to associate with this event.
-
template<typename context_t>
inline void set_symbol( - context_t &ctx,
- ::std::string s,
Sets a symbolic name for the event, useful for debugging or tracing.
- Parameters:
s – The symbolic name to associate with this event.
- inline virtual event_list from_stream(
- backend_ctx_untyped&,
- cudaStream_t,
-
inline const ::std::string &get_symbol() const#
Retrieves the symbolic name of the event.
- Returns:
The symbolic name of the event. Generates a default name if none was set.
Public Members
