Detailed Description

template<class Interpolator>
class QuantExt::InterpolatedPillarOnlyZeroCurve< Interpolator >

Zero rate curve interpolating on pillar dates only, excluding synthetic t=0.

This curve interpolates continuously compounded zero rates on actual market pillar dates only, excluding the synthetic time-zero point.

Key features:

• At t=0: Returns DF(0) = 1.0 by definition
• Left extrapolation (0 < t < t₁): Flat zero rate from first pillar
• Interpolation (t₁ ≤ t ≤ tₙ): Uses provided interpolator on pillar zero rates
• Right extrapolation (t > tₙ): Flat zero rate from last pillar
• Discount factors computed as: DF(t) = exp(-z(t) * t)
