Implementations

impl Operand

pub fn element(index: u32) -> Operand

pub fn literal<T>(literal: T) -> Operand

where T: Into<LiteralOperand>,

pub fn simple_attribute<T>( type_definition_id: T, browse_path: &str, attribute_id: AttributeId, index_range: UAString, ) -> Operand

where T: Into<NodeId>,

Creates a simple attribute operand. The browse path is the browse name using / as a separator.
