DESCRIPTION
Implements a subset of the DBIx::SearchBuilder collection methods, but
enough to do iteration over a bunch of results. Useful for displaying
the results of two unrelated searches (for the same kind of objects) in
a single list.
METHODS
new
Create a new DBIx::SearchBuilder::Union object. No arguments.
add $sb
Add a searchbuilder result (collection) to the Union object.
It must be the same type as the first object added.
First
Return the very first element of the Union (which is the first element
of the first Collection). Also reset the current pointer to that
element.
Next
Return the next element in the Union.
Last
Returns the last item
Count
Returns the total number of elements in the Union'ed Collection
GotoFirstItem
Starts the recordset counter over from the first item. the next time
you call Next, you'll get the first item returned by the database, as
if you'd just started iterating through the result set.
IsLast
Returns true if the current row is the last record in the set.
ItemsArrayRef
Return a refernece to an array containing all objects found by this
search.
Will destroy any positional state.
