A ResultSetFilter is a custom Java class deployed to Unwired Server that manipulates rows and columns of data before synchronization.
Result set filters are more versatile (and more complicated to implement) than an attribute filter implemented through a synchronization parameter, since you must write code that implements the filter, instead of simply mapping a parameter to a column to use as the filter. See Developers Reference: Server API.
- Enterprise information system (EIS) data is sent to Unwired Server.
- The result set filter filters the results, and applies those results to the CDB for a given MBO. For example, the result set filter combines two columns into one.
- The device application synchronizes with the results contained in the CDB.
The client cannot distinguish between MBOs that have had their attributes transformed through a ResultSetFilter from those that have not.
