Retrieves the total number of records in a table or number of keys in an index.
public int GetRecordCount( FilterOption eOption );
public int GetRecordCount( FilterOption eOption, bool bRefreshCount );
Remarks
If eOption is AdsExtendedReader.FilterOption.IgnoreFilters, this function will return the total number of records in the current table or cursor.
If eOption is AdsExtendedReader.FilterOption.RespectScopes, this function will return the total number of records within the current range (scope).
If eOption is AdsExtendedReader.FilterOption.RespectFilters, ranges and filters are obeyed, and this function returns the count of all records in the current range passing the current Filter.
If bRefreshCount is true, the count will be recalculated. This may be necessary when it is known that other applications are appending records to the table and a more accurate count is needed. Note that if other applications are appending records to a table, there is no guarantee that the record count will be accurate because another application may append a record immediately after the record count is retrieved. To guarantee an accurate count, an application must have opened the table exclusively or locked the table.
