ZeroRatePeriodicDiscountFactors介绍

[英]Provides access to discount factors for a currency based on a zero rate periodically-compounded curve.

This provides discount factors for a single currency.

This implementation is based on an underlying curve that is stored with maturities and zero-coupon periodically-compounded rates.
[中]提供对基于零利率周期复合曲线的货币贴现系数的访问。
这为单一货币提供了贴现系数。
这种实现基于一条基本曲线，该曲线以到期日和零息票周期复合利率存储。
