inline fun <TARGET : Any, T> BiDiLensSpec<TARGET, String>.composite(crossinline fn: BiDiLensSpec<TARGET, String>.(TARGET) -> T): Lens<TARGET, T>(source)

This allows creation of a composite object from several values from the same source.

inline fun <TARGET : Any, T> BiDiLensSpec<TARGET, String>.composite(crossinline getFn: BiDiLensSpec<TARGET, String>.(TARGET) -> T, crossinline setFn: T.(TARGET) -> TARGET): BiDiLens<TARGET, T>(source)
