Create a new SortedRecordset object (SortedRecordset class)
This shared function instantiates an empty instance of a SortedRecordset object.
Available as of Sirius Mods version 7.6, the New method is an alternative to using a Sort statement factory constructor, as described in "Declaration and instantiation".
Syntax
%sortedRecordset = [%(SortedRecordset In filOrGrp name):]New
Syntax terms
| %srecs | A declared SortedRecordset object including its file/group context. |
|---|---|
| class | Either a parenthesized class name, as in %(SortedRecordset in file foo), or a non-parenthesized variable in the class, as in %srecs.
|
Usage notes
- If you are creating an extension class of the SortedRecordset class,
you can use New in the Construct statement in the extension class:
class sordidSet extends sortedRecordset in sordid inherit ... constructor new construct %(sortedRecordset in sordid):new ... end constructor ... end class
The Sort statement constructors cannot be used for this purpose.
Example
- The New constructor has no parameters and simply
instantiates an empty instance of its class:
%srs is object SortedRecordset in sordid ... %srs = new
