public boolean isRowCountIsCalculated() throws IOException, AutomationException
Returns true if the only way to count the number of rows in the dataset is to get a cursor and count. If the data source has a faster method for getting a count of rows in a dataset, this method should return false and the optional interface IPlugInFastRowCount should be implemented on dataset helpers returned by OpenDataset. It is always safe to return true here.

- If there are interop problems.
AutomationException
- If the ArcObject component throws an exception.public boolean isOIDIsRecordNumber() throws IOException, AutomationException
It should return true if the record number of your data source is used as the Object ID, that is the Object IDs are always continuous. If true, some joins are optimized.

Creates and initializes an instance of the dataset helper class and returns its IPlugInDatasetHelper pointer. If localName is not a local name of a dataset, the method should fail and return a null pointer.
