Enum ArithmeticOperator 

pub enum ArithmeticOperator {
    Add,
    Divide,
    Multiply,
    Subtract,
}

How an applied value combines its components.

IfcArithmeticOperatorEnum, verified against IFC4 EXPRESS.

Variants

Add

.ADD.

Divide

.DIVIDE.

Multiply

.MULTIPLY.

Subtract

.SUBTRACT.

Implementations

impl ArithmeticOperator

pub fn parse(token: &str) -> Option<Self>

Parse the enum token, without its dots.

pub fn is_order_sensitive(self) -> bool

Whether operand order changes the result.

ADD and MULTIPLY are commutative, so folding a component list in file order is safe. SUBTRACT and DIVIDE are not, and IFC does not define the bracketing, so a caller folding them is choosing a convention rather than reading one.
