Structure
ATLIterateExpression
Represents an ATL iterate expression with complex syntax.
struct ATLIterateExpressionOverview
The iterate expression supports the OCL-style iterate syntax:
collection->iterate(param; accumulator : Type = defaultValue | body_expression)Example Usage
let iterateExpr = ATLIterateExpression(
source: ATLVariableExpression(name: "numbers"),
parameter: "n",
accumulator: "sum",
accumulatorType: "Integer",
defaultValue: ATLLiteralExpression(value: 0),
body: ATLBinaryExpression(
left: ATLVariableExpression(name: "sum"),
operator: .add,
right: ATLVariableExpression(name: "n")
)
