public class MultiAlgorithmDSL
extends LenskitConfigDSL

DSL delegate for configuring multiple LensKit algorithms with names and attributes. It adds two new capabilities:

• The getAttributes() property exposes the algorithm instance attributes for manipulation.
• The algorithm(String, Closure) method allows for algorithm blocks so more than one algorithm can be defined in a script.

If algorithm blocks are used in a script, then only those blocks’ algorithms are generated; a top-level algorithm is not generated. algorithm blocks also nest, and only those blocks that have no child algorithm blocks actually produce new algorithms.
