Member Function Documentation

◆ reset()

void reset ( Size size )

overridevirtual

This method should initialize the asset values to an Array of the given size and with values depending on the particular asset.

Implements DiscretizedAsset.

◆ mandatoryTimes()

std::vector< Time > mandatoryTimes ( ) const

overridevirtual

This method returns the times at which the numerical method should stop while rolling back the asset. Typical examples include payment times, exercise times and such.
