21 This module is still experimental.
22
24 Implements a subset of the DBIx::SearchBuilder collection methods, but
25 enough to do iteration over a bunch of results. Useful for displaying
26 the results of two unrelated searches (for the same kind of objects) in
27 a single list.
28
30 new
31 Create a new DBIx::SearchBuilder::Union object. No arguments.
32
33 add $sb
34 Add a searchbuilder result (collection) to the Union object.
35
36 It must be the same type as the first object added.
37
38 First
39 Return the very first element of the Union (which is the first element
40 of the first Collection). Also reset the current pointer to that
41 element.
42
43 Next
44 Return the next element in the Union.
45
46 Last
47 Returns the last item
48
49 Count
50 Returns the total number of elements in the Union'ed Collection
51
52 GotoFirstItem
53 Starts the recordset counter over from the first item. the next time
54 you call Next, you'll get the first item returned by the database, as
55 if you'd just started iterating through the result set.
56
57 IsLast
58 Returns true if the current row is the last record in the set.
59
60 ItemsArrayRef
61 Return a refernece to an array containing all objects found by this
62 search.
63
