This Methodmay be used to check the specific update behavior for a set of files. The files are identified by the NodeIdof their FileTypeinstance in the FileSystem.

GetUpdateBehavior(

[in] NodeId[] NodeIds,

[out]UpdateBehaviorUpdateBehavior);

Argument

Description

NodeIds

NodeIds of the files to install.

UpdateBehavior

If one or more NodeIdsare not found.

This Methodmay be used to check if the specified set of files are valid and complete for an installation. This should also include dependency checks if appropriate.

Note: In case of Direct-Loadingor Cached-Loadingthese checks should be part of the transfer and this method shall not be supported since it is part of the file transfer (e.g. in CloseAndCommit).

[in] NodeId[]NodeIds,

[out]ErrorCodeInt32,

[out]ErrorMessageLocalizedText);
