Request

requestHeader

RequestHeader

Common request parameters (see 7.28 for RequestHeader definition).

View

ViewDescription

Description of the View to browse (see 7.39 for ViewDescription definition). An empty ViewDescription value indicates the entire AddressSpace. Use of the empty ViewDescription value causes all References of the nodesToBrowse to be returned. Use of any other View causes only the References of the nodesToBrowse that are defined for that View to be returned.

requestedMax

ReferencesPerNode

Counter

Indicates the maximum number of references to return for each starting Node specified in the request. The value 0 indicates that the Client is imposing no limitation (see 7.5 for Counter definition).

nodesToBrowse []

BrowseDescription

A list of nodes to Browse. This structure is defined in-line with the following indented items.

nodeId

NodeId

NodeId of the Node to be browsed. If a view is provided, it shall include this Node.

browseDirection

Enum

BrowseDirection

An enumeration that specifies the direction of References to follow. It has the following values:

FORWARD_0select only forward References.

INVERSE_1 select only inverse References.

BOTH_2 select forward and inverse References.

INVALID_3 no value specified.

The returned References do indicate the direction the Server followed in the isForward parameter of the ReferenceDescription.

Symmetric References are always considered to be in forward direction therefore the isForward flag is always set to TRUE and symmetric References are not returned if browseDirection is set to INVERSE_1.

referenceTypeId

NodeId

Specifies the NodeId of the ReferenceType to follow. Only instances of this ReferenceType or its subtypes are returned.

If not specified then all References are returned and includeSubtypes is ignored.

includeSubtypes

Boolean

Indicates whether subtypes of the ReferenceType should be included in the browse. If TRUE, then instances of referenceTypeId and all of its subtypes are returned.

nodeClassMask

UInt32

Specifies the NodeClasses of the TargetNodes. Only TargetNodes with the selected NodeClasses are returned. The NodeClasses are assigned the following bits:

If set to zero, then all NodeClasses are returned.

If the NodeClass is unknown for a remote Node, the nodeClassMask is ignored.

resultMask

UInt32

Specifies the fields in the ReferenceDescription structure that should be returned. The fields are assigned the following bits:

The ReferenceDescription type is defined in 7.25.

Response

responseHeader

Response Header

Common response parameters (see 7.29 for ResponseHeader definition).

results []

BrowseResult

A list of BrowseResults. The size and order of the list matches the size and order of the nodesToBrowse specified in the request.

The BrowseResult type is defined in 7.3.

diagnosticInfos []

Diagnostic Info

List of diagnostic information for the results (see 7.8 for DiagnosticInfo definition). The size and order of the list matches the size and order of the results response parameter. This list is empty if diagnostics information was not requested in the request header or if no diagnostic information was encountered in processing of the request.
