Remarks

This interface is used to initialize a DeltaDataChanges coclass with random access.

Random access is needed when you want to use the IDataChanges::Extract method to see edits from specific tables or feature class in an XML delta file. If you do not initialize with random access, you need to step through the feature classes and tables in order using IDataChanges::GetModifiedClassesInfo. If you do not initialize with random access, an error is returned if you try to access edits from a feature class without processing the previous edits from other feature classes and tables referenced in the file.

This is only needed for delta XML files. Delta databases and delta file geodatabases support random access regardless of how the coclass is initialized.

When importing a delta file, initializing DeltaDataChanges with random access uses more memory, but performs faster than not using random access.
