Methods

Map(TFrom, TTo)

State that a value in the source generation becomes a specific value in the target generation.

IValueMapBuilder<TFrom, TTo> Map(TFrom from, TTo to)

Parameters

from TFrom

The value as it appears in the source generation.

to TTo

The value it becomes in the target generation.

Returns

IValueMapBuilder<TFrom, TTo>

The builder for continued configuration.

Remarks

Only values the map mentions are translated - anything else is carried across as it is, because a value the map stays silent about means the same thing in both generations.
