Detailed Description

template<class T> class QuantLib::TsiveriotisFernandesLattice< T >

Binomial lattice approximating the Tsiveriotis-Fernandes model.

Member Function Documentation

void rollback (DiscretizedAsset &, Time to) const [protected, virtual]

Roll back an asset until the given time, performing any needed adjustment.

Reimplemented from TreeLattice< BlackScholesLattice< T > >.

void partialRollback (DiscretizedAsset &, Time to) const [protected, virtual]

Roll back an asset until the given time, but do not perform the final adjustment.

Warning

: In version 0.3.7 and earlier, this method was called rollAlmostBack method and performed pre-adjustment. This is no longer true; when migrating your code, you'll have to replace calls such as:

                     method->rollAlmostBack(asset,t);

with the two statements:

                     method->partialRollback(asset,t);
                     asset->preAdjustValues();
