Member Function Documentation

◆ GetEntry()

BooleanArrayEntry nt::BooleanArrayTopic::GetEntry	(	ParamType	defaultValue,
		const PubSubOptions &	options = `kDefaultPubSubOptions`
	)

inline

Create a new entry for the topic.

Entries act as a combination of a subscriber and a weak publisher. The subscriber is active as long as the entry is not destroyed. The publisher is created when the entry is first written to, and remains active until either Unpublish() is called or the entry is destroyed.

Note: It is not possible to use two different data types with the same topic. Conflicts between publishers are typically resolved by the server on a first-come, first-served basis. Any published values that do not match the topic's data type are dropped (ignored), and the entry will show no new values if the data type does not match. To determine if the data type matches, use the appropriate Topic functions.

Parameters

defaultValue	default value used when a default is not provided to a getter function
options	publish and/or subscribe options

Returns: entry

◆ GetEntryEx()

BooleanArrayEntry nt::BooleanArrayTopic::GetEntryEx	(	std::string_view	typeString,
		ParamType	defaultValue,
		const PubSubOptions &	options = `kDefaultPubSubOptions`
	)

inline

Create a new entry for the topic, with specific type string.

Entries act as a combination of a subscriber and a weak publisher. The subscriber is active as long as the entry is not destroyed. The publisher is created when the entry is first written to, and remains active until either Unpublish() is called or the entry is destroyed.

Note: It is not possible to use two different data types with the same topic. Conflicts between publishers are typically resolved by the server on a first-come, first-served basis. Any published values that do not match the topic's data type are dropped (ignored), and the entry will show no new values if the data type does not match. To determine if the data type matches, use the appropriate Topic functions.

Parameters

typeString	type string
defaultValue	default value used when a default is not provided to a getter function
options	publish and/or subscribe options

Returns: entry

◆ Publish()

BooleanArrayPublisher nt::BooleanArrayTopic::Publish ( const PubSubOptions & options = kDefaultPubSubOptions )

inline

Create a new publisher to the topic.

The publisher is only active as long as the returned object is not destroyed.

Note: It is not possible to publish two different data types to the same topic. Conflicts between publishers are typically resolved by the server on a first-come, first-served basis. Any published values that do not match the topic's data type are dropped (ignored). To determine if the data type matches, use the appropriate Topic functions.

Parameters

options publish options

Returns: publisher

◆ PublishEx()

BooleanArrayPublisher nt::BooleanArrayTopic::PublishEx	(	std::string_view	typeString,
		const wpi::json &	properties,
		const PubSubOptions &	options = `kDefaultPubSubOptions`
	)

inline

Create a new publisher to the topic, with type string and initial properties.

The publisher is only active as long as the returned object is not destroyed.

Note: It is not possible to publish two different data types to the same topic. Conflicts between publishers are typically resolved by the server on a first-come, first-served basis. Any published values that do not match the topic's data type are dropped (ignored). To determine if the data type matches, use the appropriate Topic functions.

Parameters

typeString	type string
properties	JSON properties
options	publish options

Returns: publisher

◆ Subscribe()

BooleanArraySubscriber nt::BooleanArrayTopic::Subscribe	(	ParamType	defaultValue,
		const PubSubOptions &	options = `kDefaultPubSubOptions`
	)

inline

Create a new subscriber to the topic.

The subscriber is only active as long as the returned object is not destroyed.

Note: Subscribers that do not match the published data type do not return any values. To determine if the data type matches, use the appropriate Topic functions.

Parameters

defaultValue	default value used when a default is not provided to a getter function
options	subscribe options

Returns: subscriber

◆ SubscribeEx()

BooleanArraySubscriber nt::BooleanArrayTopic::SubscribeEx	(	std::string_view	typeString,
		ParamType	defaultValue,
		const PubSubOptions &	options = `kDefaultPubSubOptions`
	)

inline

Create a new subscriber to the topic, with specific type string.

The subscriber is only active as long as the returned object is not destroyed.

Note: Subscribers that do not match the published data type do not return any values. To determine if the data type matches, use the appropriate Topic functions.

Parameters

typeString	type string
defaultValue	default value used when a default is not provided to a getter function
options	subscribe options

Returns: subscriber
