Detailed Description

template<class TS> class QuantLib::BootstrapHelper< TS >

Base helper class for bootstrapping.

This class provides an abstraction for the instruments used to bootstrap a term structure.

It is advised that a bootstrap helper for an instrument contains an instance of the actual instrument class to ensure consistancy between the algorithms used during bootstrapping and later instrument pricing. This is not yet fully enforced in the available bootstrap helpers.

Member Function Documentation

void setTermStructure (TS * t) [virtual]

sets the term structure to be used for pricing Warning

Being a pointer and not a shared_ptr, the term structure is not guaranteed to remain allocated for the whole life of the rate helper. It is responsibility of the programmer to ensure that the pointer remains valid. It is advised that this method is called only inside the term structure being bootstrapped, setting the pointer to this, i.e., the term structure itself.

Reimplemented in YoYOptionletHelper, ZeroCouponInflationSwapHelper, and YearOnYearInflationSwapHelper.

Date earliestDate () const [virtual]

earliest relevant date The earliest date at which data are needed by the helper in order to provide a quote.

Date latestDate () const [virtual]

latest relevant date The latest date at which data are needed by the helper in order to provide a quote. It does not necessarily equal the maturity of the underlying instrument.
