Object Bundles

Compatibility note: this documentation applies to ELKI 0.4 and later

Object bundles in ELKI serve as an exchange format for objects in particular between the input layer, filters and the database layer. At some point, we also plan to use this for serialization using a kind of “stream bundle”.

When using object bundles, you should understand the following principles:


A parser loads data from a file and builds a bundle. However, it also lets go of the data afterwards. One or more filters may successively be applied to the data and change it completely. When returing the data to the data loader, they however also let go of it. Finally when loading the data into a database, the records might be written to disk and be garbage collected.
