A Static result set is one where the original data source (a result set object) is copied to a process
private global upon instantiation. Future data requests then use that snapshot instead of the original
data.
Advance the result set cursor to the next row. Returns 0 if the cursor is at the end of the
result set.
The global structure consists of a base $list with individual nodes for columns. The base $list() can contain zero or more column
values. Additional column values are stored in the global subscripted by column number and equal to the column value.
Inherited description: This callback method is invoked by the %New() method to
provide notification that a new instance of an object is being created.
If this method returns an error then the object will not be created.
It is passed the arguments provided in the %New call.
When customizing this method, override the arguments with whatever variables and types you expect to receive from %New().
For example, if you're going to call %New, passing 2 arguments, %OnNew's signature could be:
Method %OnNew(dob as %Date = "", name as %Name = "") as %Status
If instead of returning a %Status code this returns an oref and this oref is a subclass of the current
class then this oref will be the one returned to the caller of %New method.
