Method: Leaf::Collection#initialize

Defined in:
lib/leaf/collection.rb

#initialize(page, per_page, total = nil) ⇒ Collection

Arguments to the constructor are the current page number, per-page limit and the total number of entries. The last argument is optional because it is best to do lazy counting; in other words, count conditionally after populating the collection using the replace method.

Raises:



29
30
31
32
33
34
35
36
