Function Documentation
QOpcUa::ErrorCategory QOpcUa::errorCategory(QOpcUa::UaStatusCode statusCode)
Converts statusCode to an ErrorCategory. ErrorCategory can be used in cases where the exact error is not important.
For error handling dependent on status codes, the full status code must be used instead. The meaning of the status codes for the different services is documented in OPC UA part 4.
If statusCode has not been categorized, UnspecifiedError is returned. In this case, the user must check the full status code.
[since QtOpcUa 5.14] bool QOpcUa::isSecurePolicy(const QString &securityPolicy)
Returns true if securityPolicy is a secure policy, false otherwise.
This function was introduced in QtOpcUa 5.14.
bool QOpcUa::isSuccessStatus(QOpcUa::UaStatusCode statusCode)
This method can be used to check if a call has successfully finished.
Returns true if statusCode's severity field is Good.
QOpcUa::Types QOpcUa::metaTypeToQOpcUaType(QMetaType::Type type)
Returns the Qt OPC UA type from type. In case the type does not map, QOpcUa::Undefined is returned.
QString QOpcUa::namespace0Id(QOpcUa::NodeIds::Namespace0 id)
Returns a node id string for the namespace 0 identifier id.
QOpcUa::NodeIds::Namespace0 QOpcUa::namespace0IdFromNodeId(const QString &nodeId)
Returns the enum value from QOpcUa::NodeIds::Namespace0 for nodeId.
If the node id is not in namespace 0 or doesn't have a numeric identifier which is part of the OPC Foundation's NodeIds.csv file, Unknown is returned.
If Qt OPC UA has been configured with -no-feature-ns0idnames, the check if the numeric identifier is part of the NodeIds.csv file is omitted. If the node id is in namespace 0 and has a numeric identifier, the identifier is returned regardless if it is part of the QOpcUa::NodeIds::Namespace0 enum.
QString QOpcUa::namespace0IdName(QOpcUa::NodeIds::Namespace0 id)
Returns the name of the namespace 0 node id id.
If id is unknown or Qt OPC UA has been configured with -no-feature-ns0idnames, an empty string is returned.
bool QOpcUa::nodeIdEquals(const QString &first, const QString &second)
Returns true if the two node ids first and second have the same namespace index and identifier. A node id string without a namespace index is assumed to be in namespace 0.
QString QOpcUa::nodeIdFromByteString(quint16 ns, const QByteArray &identifier)
Creates a node id string from the namespace index ns and the byte string identifier.
See also QOpcUaNode.
QString QOpcUa::nodeIdFromGuid(quint16 ns, const QUuid &identifier)
Creates a node id string from the namespace index ns and the GUID identifier.
See also QOpcUaNode.
QString QOpcUa::nodeIdFromInteger(quint16 ns, quint32 identifier)
Creates a node id string from the namespace index ns and the integer identifier.
See also QOpcUaNode.
QString QOpcUa::nodeIdFromReferenceType(QOpcUa::ReferenceTypeId referenceType)
Creates a node id string for the reference type id referenceType.
QString QOpcUa::nodeIdFromString(quint16 ns, const QString &identifier)
Creates a node id string from the namespace index ns and the string identifier.
See also QOpcUaNode.
bool QOpcUa::nodeIdStringSplit(const QString &nodeIdString, quint16 *nsIndex, QString *identifier, char *identifierType)
Splits the node id string nodeIdString in its components. The namespace index of the node id will be copied into nsIndex. The identifier string is copied into identifier and the identifier type (i, s, g, b) is copied into identifierType.
Returns true if the node id could be split successfully.
For example, "ns=1;s=MyString" is split into 1, 's' and "MyString". If no namespace index is given, ns=0 is assumed.
size_t QOpcUa::qHash(const QOpcUa::NodeAttribute &attr)
Returns a QHash key for attr.
QString QOpcUa::statusToString(QOpcUa::UaStatusCode statusCode)
Returns a textual representation of statusCode.
Currently, this is the name of the enum value but may be a real message in future releases.
