row().cache()

Since: DataTables 1.10

Get the DataTables cached data for the selected row.

Description

DataTables caches data for searching and ordering in order for those operations to run as quickly as possible when they are required.

Cached data is not guaranteed to be available at any particular moment. If DataTables hasn't requested the data, it won't have been cached. This is particularly obvious when using the order option and a sort hasn't been performed on a column. Invalidation of data will also cause the cache to be removed.

It should be noted that this method is required as DataTables has the ability to use different data for its different operations (searching, ordering, display etc) - see columns.data and columns.render for further information. If you don't want the cached data, rows().data() provides access to the original data array / object given to, or created by DataTables. If you aren't using orthogonal data for the different operations of DataTables, then this method is of limited used.

Note that this method is primarily aimed at plug-in developers who require access to the internal data that DataTables has stored.
