Search Method (Selection)
Search and retrieve specific rows in this
Selection that satisfy the criteria set in the . If no query filter is set, all rows will be retrieved. This method must be called on the MCT. Use QueuedTask.Run.
Parameters
- queryFilter
-
This argument is optional. If unset or set to null, a default query filter will be used, which will cause all rows to be returned.
- useRecyclingCursor
- If set to true, all the entries in RowCursor will reference the most current row returned by Current. To ensure all the entries in RowCursor remain unique, set to false.
Return Value
A
RowCursor that encapsulates the retrieved rows.
