## Detailed Description

Term structure with an added vector of spreads on the zero-yield rate.

The zero-yield spread at any given date is linearly interpolated between the input data.

Note:
  This term structure will remain linked to the original structure, i.e., any changes in the latter will be reflected in this structure as well.

void update | ( |  | ) | `[protected, virtual]`

This method must be implemented in derived classes. An instance of Observer does not call this method directly: instead, it will be called by the observables the instance registered with when they need to notify any changes.

Reimplemented from YieldTermStructure.
