The WriteMask type is a typedef for QFlags <WriteMaskBit>. It stores an OR combination of WriteMaskBit values.
转换 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.
若 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
)
返回
true
if
securityPolicy
is a secure policy,
false
否则。
This function was introduced in QtOpcUa 5.14.
This method can be used to check if a call has successfully finished.
返回
true
if
statusCode
's serverity 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
被返回。
该函数在 Qt 5.13 引入。
Returns a node id string for the namespace 0 identifier id .
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, 未知 被返回。
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 枚举。
Returns the name of the namespace 0 node id id .
若 id is unknown or Qt OPC UA has been configured with -no-feature-ns0idnames, an empty string is returned.
返回
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.
Creates a node id string from the namespace index ns and the byte string 标识符 .
另请参阅 QOpcUaNode .
Creates a node id string from the namespace index ns and the GUID 标识符 .
另请参阅 QOpcUaNode .
Creates a node id string from the namespace index ns and the integer 标识符 .
另请参阅 QOpcUaNode .
Creates a node id string for the reference type id referenceType .
Creates a node id string from the namespace index ns and the string 标识符 .
另请参阅 QOpcUaNode .
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 标识符 and the identifier type (i, s, g, b) is copied into identifierType .
返回
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.
返回 QHash key for attr .
Returns a textual representation of statusCode .
Currently, this is the name of the enum value but may be a real message in future releases.
