getAll method
The getAll() method of the IDBIndex
interface retrieves all objects that are inside the index.
There is a performance cost associated with looking at the value
property
of a cursor, because the object is created lazily. To use a feature
like getAll(), the browser has to create all the objects at once. If you
are just interested in looking at each of the keys, for instance, it is
more efficient
to use a
cursor. If
you are trying to get an
array of all the objects in an object store, though, you should
use getAll().
