FastUnloadTask class

The FastUnloadTask class is used for retrieving data from a Fast/Unload task as it is output.

The only way to instantiate a FastUnloadTask object is via the FastUnloadTask method of the Recordset class.

The FastUnloadTask class is only available to customers licensed for the Fast/Unload User Language Interface, and it is only available in Sirius Mods version 6.7 and later.

FastUnloadTask objects always have one of three states, as described by values of the FastUnloadTaskState enumeration:

Started	The initial state of a FastUnloadtask object: no GetNextRecord (FastUnloadTask function) method calls have yet been issued.
HaveRecord	GetNextRecord has been called, and the call did, indeed, retrieve another record from Fast/Unload.
Done	GetNextRecord has been called, and the call discovered that there were no more records to retrieve, that is, Fast/Unload had terminated.

FastUnloadTask example

The following code prints the contents of set of fields in a fixed format, using Fast/Unload to extract the fields. There is probably little benefit to using Fast/Unload here instead of native Model 204 field access facilities, but the example does show some of the FastUnloadtask methods:

b %rs is object recordSet in file sirFiled %ft is object fastUnloadTask %listi is object stringList find records to %rs end find %listi = new text to %listi FOR EACH RECORD PUT FILE AS STRING(8) PUT RECTYPE AS STRING(8) PUT DATE AS STRING(12) OUTPUT END FOR end text %ft = %rs:fastUnloadTask(%listi, parameters='NEBUFF=2', - reportToStringlist=true) repeat while %ft:getNextRecord ne done print %ft:currentRecord end repeat %ft:report:print print %ft:returnCode end
