Detailed Description

Discretized option on a given asset.

Warning:
it is advised that derived classes take care of creating and initializing themselves an instance of the underlying.

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.

Reimplemented in DiscretizedSwaption.

◆ 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.

Note
The returned values are not guaranteed to be sorted.

Implements DiscretizedAsset.
