DESCRIPTION

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

METHODS

30       new
31

33
34       add $sb
35
36       Add a searchbuilder result (collection) to the Union object.
37
38       It must be the same type as the first object added.
39
40       First
41
42       Return the very first element of the Union (which is the first element
43       of the first Collection).  Also reset the current pointer to that ele‐
44       ment.
45
46       Next
47
48       Return the next element in the Union.

55
56       Returns the total number of elements in the Union'ed Collection
57
58       GotoFirstItem
59
60       Starts the recordset counter over from the first item. the next time
61       you call Next, you'll get the first item returned by the database, as
62       if you'd just started iterating through the result set.
63
64       IsLast
65
66       Returns true if the current row is the last record in the set.
67
68       ItemsArrayRef
69
70       Return a refernece to an array containing all objects found by this
71       search.
