Detailed Description

Bond Basket.

This class holds a basket of defaultable bonds along with the pool of relevant names. There may be more bonds than names involved, e.g. several different bonds with same issuer.

The class provides tools for evaluating basket cash flows of different kinds (interest, principal) for scenarios of default times stored for all names involved in the Pool structure.

For further information refer to the detailed QuantExt documentation.
