Function Documentation

browse() [1/2]

BrowseResponse opcua::services::browse ( Client &  connection, const BrowseRequest &  request  )

noexcept

Discover the references of one or more nodes (client only).

Parameters

connection	Instance of type Client
request	Browse request

Referenced by opcua::services::browseAll(), and opcua::Node< Connection >::browseParent().

browse() [2/2]

template<typename T >

BrowseResult opcua::services::browse ( T &  connection, const BrowseDescription &  bd, uint32_t  maxReferences  )

noexcept

Discover the references of a specified node.

Parameters

connection	Instance of type Server or Client
bd	Browse description
maxReferences	The maximum number of references to return (0 if no limit)

browseAll()

template<typename T >

Result< std::vector< ReferenceDescription > > opcua::services::browseAll	(	T &	connection,
		const BrowseDescription &	bd
	)

Discover all the references of a specified node (without calling browseNext).

Parameters

connection	Instance of type Server or Client
bd	Browse description

Definition at line 333 of file view.hpp.

Referenced by opcua::Node< Connection >::browseReferencedNodes(), and opcua::Node< Connection >::browseReferences().

browseAsync() [1/2]

template<typename CompletionToken >

auto opcua::services::browseAsync	(	Client &	connection,
		const BrowseDescription &	bd,
		uint32_t	maxReferences,
		CompletionToken &&	token
	)

Discover the references of a specified node.

Parameters

connection	Instance of type Server or Client
bd	Browse description
maxReferences	The maximum number of references to return (0 if no limit)
token	The completion token that will be used to produce a completion handler, which will be called when the operation completes. Potential completion tokens include useFuture, useDeferred, useDetached, or a function (object) with the correct completion signature. The function signature of the completion handler must be: void(BrowseResult&)

Returns

• void if token is a callback function (object)
• std::future<BrowseResult> if token is of type UseFutureToken
• auto(auto&& token) callable for deferred execution if token is of type UseDeferredToken
• void if token is of type UseDetachedToken

Definition at line 76 of file view.hpp.

browseAsync() [2/2]

template<typename CompletionToken >

auto opcua::services::browseAsync	(	Client &	connection,
		const BrowseRequest &	request,
		CompletionToken &&	token
	)

Discover the references of one or more nodes (client only).

Parameters

connection	Instance of type Client
request	Browse request
token	The completion token that will be used to produce a completion handler, which will be called when the operation completes. Potential completion tokens include useFuture, useDeferred, useDetached, or a function (object) with the correct completion signature. The function signature of the completion handler must be: void(BrowseResponse&)

Returns

• void if token is a callback function (object)
• std::future<BrowseResponse> if token is of type UseFutureToken
• auto(auto&& token) callable for deferred execution if token is of type UseDeferredToken
• void if token is of type UseDetachedToken
