Public Types
using	Ptr = std::shared_ptr<EventTypeWithSymbol<Symbol>>
	The alias to a type of shared pointer to the EventTypeWithSymbol's child object.
Public Types inherited from EventType
using	Ptr = std::shared_ptr<EventType>
	The alias to a type of shared pointer to the EventType object.
Public Types inherited from SharedEntity
using	Ptr = std::shared_ptr<SharedEntity>
	The alias to a type of shared pointer to the SharedEntity object.

Public Member Functions
virtual const Symbol &	getEventSymbol () const &noexcept=0
	Returns event symbol that identifies this event type in subscription.
virtual const std::optional< Symbol > &	getEventSymbolOpt () const &noexcept=0
	Returns event symbol that identifies this event type in subscription.
virtual void	setEventSymbol (const Symbol &eventSymbol) noexcept=0
	Changes event symbol that identifies this event type in subscription.
Public Member Functions inherited from EventType
virtual std::int64_t	getEventTime () const noexcept
	Returns time when event was created or zero when time is not available.
virtual void	setEventTime (std::int64_t) noexcept
	Changes event creation time.
virtual void *	toGraal () const =0
	Allocates memory for the dxFeed Graal SDK structure (recursively if necessary).
virtual void	assign (std::shared_ptr< EventType > event)
	Replaces the contents of the event.
std::string	toString () const override
	Returns a string representation of the current object.
Public Member Functions inherited from SharedEntity
template<typename T>
bool	is () const noexcept
	Checks that pointer to the current type could be converted to type T* In other words: whether type T belongs to the type hierarchy in which the current type resides.
template<typename T>
std::shared_ptr< T >	sharedAs () noexcept
	Returns a pointer to the current object wrapped in a smart pointer to type T.
template<typename T>
std::shared_ptr< T >	sharedAs () const noexcept
	Returns a pointer to the current object wrapped in a smart pointer to type T.
Public Member Functions inherited from Entity
virtual	~Entity () noexcept=default
	The default virtual d-tor.
