Delivering Recordset Data To Flash Applications In Coldfusion Mx - MACROMEDIA FLASH REMOTING MX-USING FLASH REMOTING FOR FLASH MX 2004 ACTIONSCRIPT 2.0 Use Manual

The following example filters a RecordSet object to produce a new RecordSet object with records
that have contact fields that start with a specific letter:
var mySelectionFunction = function(aRecord, letter)
{
return (aRecord.contact.charAt(0) == letter);
}
contact_grid.dataProvider = myRecordSet.filter(mySelectionFunction,
theLetter);
In this example:
•
The
contact_grid
•
The
myRecordSet
function.
•
The
theLetter
•
The
mySelectionFunction()
if the first letter of the record matches the specified letter.
•
The
myRecordSet.filter()
mySelectionFunction()
which the
mySelectionFunction()
object.
•
The Contact_grid component's
myRecordSet object, generated by the
contact_grid
Note: For RecordSet objects that have 2,000 or fewer records, the
less than one second to finish. The length of time to filter RecordSet objects increases rapidly as the
number of records grows.

Delivering RecordSet data to Flash applications in ColdFusion MX

By default, Flash Remoting returns a RecordSet object to the Flash client in a single response
when the application server finishes retrieving the data.
In ColdFusion MX, if you expect to return a large record set and the available data transmission
speeds are slow, such as when using dial-up modem, you can choose to return a record set from
the application server in increments. Incremental record sets are also known as pageable record sets.
When you use pageable record sets, the following events occur:
•
On the server, the record set is held in session data, and server-side Flash Remoting RecordSet
service provides access to the records.
•
On the client, the RecordSet object can download records when needed by the Flash
application.
