Properties
| Name | Description |
|---|---|
| Description | Gets or sets the value of the optional Description attribute which shall explain the meaning of the node. |
| DisplayName | Gets or sets the value of the DisplayName attribute which defines the localizable name of the node. |
| Has | Gets a value indicating whether there exists any pending change on the node. |
| Name | Gets or sets the value of the BrowseName attribute which defines the non-localizable human-readable name used when browsing the address space. |
| Namespace | Gets the namespace of the node. |
| Parent | Gets the parent node of the node. |
| PendingChanges | Gets a value indicating the changes performed on the node since their last notification. |
| Tag | Gets or sets the object that contains additional user data about the node. |
| UserWriteAccess | Gets or sets the value of the optional UserWriteAccess attribute which exposes the possibilities of a client to write the attributes of the node taking user access rights into account. |
| WriteAccess | Gets or sets the value of the optional WriteAccess attribute which exposes the posibilities of a client to write the attributes of the node. |
