TFloClientDataset.EOF

EOF stands for End-Of-File, and this indicates whether the data set is at the end of its records.

If EOF returns True then there are no more records in this data set.

If EOF returns False then more records exist.

Typically this is used to determine whether there are any records at all within the data set - if you have just started working with the data set and it returns True then there are no records.

This is also good for looping through a data set. While the data set is not EOF you can do something with its data, and then move to the next record.

Declaration: property EOF: Boolean

Remember, that <DatasetName> in these examples is a placeholder for the actual name of your data set as per your Map.

procedure OnMapEvent(var Value:Variant);
begin
 //Check EOF to see if any more records exist
 if <DatasetName>.EOF then
    LogInfo('There are no more records in this dataset')
end;

procedure OnMapEvent(var Value:Variant);
begin
 //loop data set until end of its records
 while not <DatasetName>.EOF do
 begin
 do something...
 //move to the next record
    <DatasetName>.Next;
 end;
end;
