## Detailed Description

### template<class Arguments, class Results>
class QuantLib::LatticeShortRateModelEngine< Arguments, Results >

Engine for a short-rate model specialized on a lattice.

Derived engines only need to implement the `calculate()` method

## Member Function Documentation

void update | ( |  | ) | `[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 GenericEngine< Arguments, Results >.
