## Detailed Description

The abstract class QuantLib::YieldTermStructure provides the common interface to concrete yield-rate term structure models. Among others, methods are declared which return instantaneous forward rate, discount factor, and zero rate at a given date. Adapter classes are provided which already implement part of the required methods, thus allowing the programmer to define only the non-redundant part.

## Typedef Documentation

typedef InterpolatedDiscountCurve<LogLinear> DiscountCurve

Term structure based on log-linear interpolation of discount factors.

Log-linear interpolation guarantees piecewise-constant forward rates.

typedef InterpolatedForwardCurve<BackwardFlat> ForwardCurve

Term structure based on flat interpolation of forward rates.

typedef InterpolatedPiecewiseZeroSpreadedTermStructure<Linear> PiecewiseZeroSpreadedTermStructure

Piecewise zero-spreaded yield curve based on linear interpolation of zero rates.

typedef InterpolatedZeroCurve<Linear> ZeroCurve

Term structure based on linear interpolation of zero yields.
