◆ AttributeId

enum class opcua::AttributeId : int32_t
strong

Attribute identifiers.

See also
UA_AttributeId
https://reference.opcfoundation.org/Core/Part3/v105/docs/5.9
Enumerator
NodeId 

Unambiguous identifier of a node.


NodeClass 

Identifies the class of the node.


BrowseName 

A non-localised human-readable name used to browse the address space.

The browse name of a reference type must be unique in a server.


DisplayName 

The localized name of the node.


Description 

Explains the meaning of the node in a localized text.


WriteMask 

Exposes the possibilities of a client to write the attributes of the node.


UserWriteMask 

Exposes the possibilities of a client to write the attributes of the node.

In contrast to the write mask, the user write mask is taking access rights into account.


IsAbstract 

If a reference is abstract, no reference of this type shall exist, only of its subtypes.


Symmetric 

If a reference is symmetric, it can seen from both the source and target node.


InverseName 

The inverse name describes the reference type as seen from the target node.

For example, the reference type HasSubtype has the inverse name HasSupertype.


ContainsNoLoops 

Indicates that by following the references in the context of the view there are no loops.


EventNotifier 

Indicates if the node can be used to subscribe to events or the read/write historic events.


Value 

The most recent value of the variable that the server has.


DataType 

The NodeId of the data type definition for the Value attribute.


ValueRank 

Indicates whether the Value attribute of the variable node is an array and how many dimensions the array has.

See also
ValueRank
ArrayDimensions 

Specifies the maximum supported length of each dimension of the Value attribute.

Should be unspecified if ValueRank <= 0 (ValueRank::Any, ValueRank::Scalar, ValueRank::ScalarOrOneDimension, ValueRank::OneOrMoreDimensions). The dimension 0 is a wildcard and the actual value may have any length in this dimension.


AccessLevel 

Indicate how the value of a variable can be accessed (read/write) and if it contains current and/or historic data.


UserAccessLevel 

Indicates how the value of a variable can be accessed (read/write) and if it contains current and/or historic data.

In contrast to the AccessLevel, the UserAccessLevel is taking access rights into account.


MinimumSamplingInterval 

Specifies (in milliseconds) how fast the server can reasonably sample the value for changes.

A minimum sampling interval of 0 indicates that the server is to monitor the item continuously. A minimum sampling interval of -1 means indeterminate.


Historizing 

Indicates whether the server is actively collecting data for the history of the variable.


Executable 

Indicates if the method is currently executable.


UserExecutable 

Indicates if the method is currently executable taking user access rights into account.


DataTypeDefinition 

Provides the meta data and encoding information for custom data types.

See also
https://reference.opcfoundation.org/Core/Part3/v105/docs/5.8.3


RolePermissions 

Permissions that apply to a node.

See also
https://reference.opcfoundation.org/Core/Part3/v105/docs/5.2.9


UserRolePermissions 

Specifies the permissions that apply to a node for all roles granted to current session.

See also
https://reference.opcfoundation.org/Core/Part3/v105/docs/5.2.10


AccessRestrictions 

Specifies access restrictions that apply to a node.

See also

◆ NodeClass
