Method Detail

includeOptionalNode

default boolean includeOptionalNode(NodeId typeDefinitionId,
                                    QualifiedName browseName)

Called determine whether the optional member named browseName should be added to an instantiated Node of the type identified by typeDefinitionId

Parameters:

typeDefinitionId - the type definition id of the UaNode being instantiated.

browseName - the QualifiedName of the optional member.

Returns:

true if the optional member named browseName should be added.

onMethodAdded

default void onMethodAdded(@Nullable
                           @Nullable UaObjectNode parent,
                           UaMethodNode instance)

Called when a UaMethodNode has been added to a UaObjectNode somewhere in the instance hierarchy.

Parameters:

parent - the UaObjectNode the method was added to.

instance - the UaMethodNode instance.

onObjectAdded

default void onObjectAdded(@Nullable
                           @Nullable UaNode parent,
                           UaObjectNode instance,
                           NodeId typeDefinitionId)

Called when a UaObjectNode has been added to a parent UaNode by a hierarchical reference somewhere in the instance hierarchy.

If parent is null then instance is the root of the instance hierarchy.

Parameters:

parent - the parent UaNode.

instance - the UaObjectNode instance.

typeDefinitionId - the NodeId of the ObjectTypeDefinition.

onVariableAdded

default void onVariableAdded(@Nullable
                             @Nullable UaNode parent,
                             UaVariableNode instance,
                             NodeId typeDefinitionId)

Called when a UaVariableNode has been added to a parent UaNode by a hierarchical reference somewhere in the instance hierarchy.

If parent is null then instance is the root of the instance hierarchy.

Parameters:

parent - the parent UaNode.

instance - the UaVariableNode instance.

typeDefinitionId - the NodeId of the VariableTypeDefinition.
