dpp::event_dispatch_t Struct Reference

Base event parameter struct. Each event you receive from the library will have its parameter derived from this class. The class contains the raw event data, and a pointer to the current shard's dpp::discord_client object. You can also use this object to cancel the current event, meaning that any listeners after yours do not get notified of the current event if you call it. More...

Detailed Description

Base event parameter struct. Each event you receive from the library will have its parameter derived from this class. The class contains the raw event data, and a pointer to the current shard's dpp::discord_client object. You can also use this object to cancel the current event, meaning that any listeners after yours do not get notified of the current event if you call it.

Constructor & Destructor Documentation

event_dispatch_t() [1/5]

dpp::event_dispatch_t::event_dispatch_t ( )

default

Construct a new event_dispatch_t object.

event_dispatch_t() [2/5]

dpp::event_dispatch_t::event_dispatch_t ( const event_dispatch_t &  rhs )

default

Construct a new event_dispatch_t object.

Parameters

rhs	event_dispatch_t object to copy from

event_dispatch_t() [3/5]

dpp::event_dispatch_t::event_dispatch_t ( event_dispatch_t &&  rhs )

default

Construct a new event_dispatch_t object.

Parameters

rhs	event_dispatch_t object to move from

event_dispatch_t() [4/5]

dpp::event_dispatch_t::event_dispatch_t	(	discord_client *	client,
		const std::string &	raw
	)

Construct a new event_dispatch_t object.

Parameters

client	The shard the event originated on. May be a nullptr, e.g. for voice events
raw	Raw event data as JSON or ETF

event_dispatch_t() [5/5]

dpp::event_dispatch_t::event_dispatch_t	(	discord_client *	client,
		std::string &&	raw
	)

raw	Raw event data as JSON or ETF

~event_dispatch_t()

virtual dpp::event_dispatch_t::~event_dispatch_t ( )

virtualdefault

Member Function Documentation

cancel_event() [1/2]

event_dispatch_t& dpp::event_dispatch_t::cancel_event

(

)

Cancels the event in progress. Any other attached lambdas for this event after this one are not called.

Warning

This will modify the event object in a non-thread-safe manner.

Returns

const event_dispatch_t& reference to self for chaining

cancel_event() [2/2]

const event_dispatch_t& dpp::event_dispatch_t::cancel_event

(

)

const

Cancels the event in progress. Any other attached lambdas for this event after this one are not called.

Warning

This will modify the event object in a non-thread-safe manner.

Returns

const event_dispatch_t& reference to self for chaining

is_cancelled()

bool dpp::event_dispatch_t::is_cancelled

(

)

const

Returns true if the event is cancelled. Note that event cancellation is a thread local state, and not stored in the object (because object which can be cancelled is const during the event, and cannot itself contain the changeable state).

Returns

true if the event is cancelled

operator=() [1/2]

event_dispatch_t& dpp::event_dispatch_t::operator= ( const event_dispatch_t &  rhs )

default

Copy another event_dispatch_t object.

Parameters

rhs	The event to copy from

operator=() [2/2]

event_dispatch_t& dpp::event_dispatch_t::operator= ( event_dispatch_t &&  rhs )

default

Move from another event_dispatch_t object.

Parameters

rhs	The event to move from

Member Data Documentation

cancelled

bool dpp::event_dispatch_t::cancelled = false

mutable

Whether the event was cancelled using cancel_event().

from

discord_client* dpp::event_dispatch_t::from = nullptr

Shard the event came from. Note that for some events, notably voice events, this may be nullptr.

raw_event

std::string dpp::event_dispatch_t::raw_event = {}

Raw event data. If you are using json on your websocket, this will contain json, and if you are using ETF as your websocket protocol, it will contain raw ETF data.
