Odpověď:
Průběh zatížení na linii je definován pomocí atributu "Distribution". Atribut "Distribution" je typu "LoadDistributionType" a položky v poli se seznamem jsou typu "String", takže je vyžadována konverze typu. Funkce "GetLoadDistributionType" převede položku seznamu typu String na LoadDistributionType.
