view ¶

view(
    *,
    nodeId=None,
    browseName=None,
    displayName=None,
    description=None,
    containsNoLoops=True,
    eventNotifier=0,
    writeMask=0,
    userWriteMask=0,
    rolePermissions=None,
    accessRestrictions=0,
    parent="i=87",
    referenceType="i=35",
    references=None,
    ns=None,
    server=_UNSET
)

Declare or immediately create an OPC UA View node.

A View narrows browsing to a chosen subset of the address space. The references listed in references are the View's members; nodes stay owned by their original parents.

The return value is a live ViewNode when a server is resolved, and an unmaterialized declaration otherwise. Resolution follows the same rules as declared type instances: an explicit server wins, then a live parent, and calls made while a registered namespace module is being evaluated stay declarations until server.ns.append(module) runs.

Parameters:

Name	Type	Description	Default
`nodeId`	`Optional[NodeIdLike]`	NodeId of the View node. Allocated in `ns` when omitted.	`None`
`browseName`	`Optional[str]`	BrowseName of the node. Defaults to `"View"`.	`None`
`displayName`	`Optional[LocalizedTextLike]`	DisplayName of the node. Defaults to the BrowseName.	`None`
`description`	`Optional[LocalizedTextLike]`	Description attribute of the node.	`None`
`containsNoLoops`	`bool`	ContainsNoLoops attribute, asserting that browsing the View cannot revisit a node.	`True`
`eventNotifier`	`int`	EventNotifier attribute of the node.	`0`
`writeMask`	`int`	WriteMask attribute of the node.	`0`
`userWriteMask`	`int`	UserWriteMask attribute of the node.	`0`
`rolePermissions`	`Optional[Mapping[Any, int]]`	RolePermissions, as a mapping of role to `o6.Permission` mask.	`None`
`accessRestrictions`	`int`	AccessRestrictions attribute of the node.	`0`
`parent`	`Any`	Node or declaration that owns the View. Defaults to the standard `ViewsFolder` (`i=87`).	`'i=87'`
`referenceType`	`NodeIdLike`	ReferenceType linking the View to its parent. Defaults to `Organizes`.	`'i=35'`
`references`	`Optional[list[Any]]`	Nodes that make up the View's contents.	`None`
`ns`	`Optional[str]`	Shortname of the declaring namespace. Inferred from `nodeId` when that carries a namespace.	`None`
`server`	`Any`	Server that should create the node. `None` forces a declaration.	`_UNSET`
