WARNING
This module is still experimental.

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 reference to an array containing all objects found by this search.

Will destroy any positional state.
