Detailed Description

This class stores common connection parameters like the session timeout, the secure channel lifetime and the localeIds.

The information from this class is currently only used by the open62541 backend.

Member Function Documentation


Constructs a connection settings object.

QOpcUaConnectionSettings::QOpcUaConnectionSettings(const QOpcUaConnectionSettings &other)

Constructs a connection settings object with the values of other.

[noexcept] QOpcUaConnectionSettings::QOpcUaConnectionSettings(QOpcUaConnectionSettings &&other)

Move-constructs a new connection settings object from other.

Note: The moved-from object other is placed in a partially-formed state, in which the only valid operations are destruction and assignment of a new value.

[noexcept] QOpcUaConnectionSettings::~QOpcUaConnectionSettings()

Destroys this connection settings object.

std::chrono::milliseconds QOpcUaConnectionSettings::connectTimeout() const

Returns the connect timeout.

This value determines how long the connect will wait for a reply.

See also setConnectTimeout().

std::chrono::milliseconds QOpcUaConnectionSettings::requestTimeout() const

Returns the request timeout.

This value determines how long a synchronous service call will wait for a reply.

See also setRequestTimeout().

std::chrono::milliseconds QOpcUaConnectionSettings::secureChannelLifeTime() const

Returns the secure channel lifetime.

See also setSecureChannelLifeTime().

QStringList QOpcUaConnectionSettings::sessionLocaleIds() const

Returns the session locale ids.

See also setSessionLocaleIds().

std::chrono::milliseconds QOpcUaConnectionSettings::sessionTimeout() const

Returns the requested session timeout.

See also setSessionTimeout().

void QOpcUaConnectionSettings::setConnectTimeout(std::chrono::milliseconds timeout)

Sets timeout as the new connect timeout.

See also connectTimeout().

void QOpcUaConnectionSettings::setRequestTimeout(std::chrono::milliseconds timeout)

Sets timeout as the new request timeout.

See also requestTimeout().

void QOpcUaConnectionSettings::setSecureChannelLifeTime(std::chrono::milliseconds lifeTime)

Sets lifeTime as the new secure channel lifetime.

For details, see https://reference.opcfoundation.org/v104/Core/docs/Part4/5.5.2/#Table11

See also secureChannelLifeTime().

void QOpcUaConnectionSettings::setSessionLocaleIds(const QStringList &localeIds)

Sets localeIds as the new list of locale IDs. This setting is currently not supported by the open62541 backend.

For details, see https://reference.opcfoundation.org/v104/Core/docs/Part4/5.6.3/#Table17

See also sessionLocaleIds().

void QOpcUaConnectionSettings::setSessionTimeout(std::chrono::milliseconds timeout)

Sets timeout as the new requested session timeout.

For details, see https://reference.opcfoundation.org/v104/Core/docs/Part4/5.6.2/#Table15

See also sessionTimeout().

[noexcept] void QOpcUaConnectionSettings::swap(QOpcUaConnectionSettings &other)

Swaps connection settings object other with this connection settings object. This operation is very fast and never fails.

QOpcUaConnectionSettings &QOpcUaConnectionSettings::operator=(const QOpcUaConnectionSettings &rhs)

Sets the values from rhs in this connection settings object.

[noexcept] QOpcUaConnectionSettings &QOpcUaConnectionSettings::operator=(QOpcUaConnectionSettings &&other)

Move-assigns other to this QOpcUaConnectionSettings instance.

Note: The moved-from object other is placed in a partially-formed state, in which the only valid operations are destruction and assignment of a new value.

[noexcept] bool operator!=(const QOpcUaConnectionSettings &rhs, const QOpcUaConnectionSettings &rhs)

Returns true if lhs does not contain the same connection settings as rhs; otherwise returns false.
