示例1: idfObject
TEST_F(UnitsFixture,IddUnits_DefaultValue) {
IdfObject idfObject(IddObjectType::OS_Building);
// IdfObject::getQuantity(unsigned index, bool returnDefault=false, bool returnIP=false) const;
// this field is empty but has a default value of 3 m
EXPECT_TRUE(idfObject.getQuantity(OS_BuildingFields::NominalFloortoFloorHeight, false).empty());
OSOptionalQuantity siQ = idfObject.getQuantity(OS_BuildingFields::NominalFloortoFloorHeight, true, false);
ASSERT_FALSE(siQ.empty());
OptionalUnit mUnit = createUnit("m");
ASSERT_TRUE(mUnit);
EXPECT_EQ(*mUnit, siQ.get().units());
EXPECT_EQ(3.0, siQ.get().value());
OSOptionalQuantity ipQ = idfObject.getQuantity(OS_BuildingFields::NominalFloortoFloorHeight, true, true);
