ATLCollectionExpression

struct ATLCollectionExpression

Overview

Collection expressions handle OCL-style collection operations such as select, collect, exists, forAll, and other iterator-based operations on collections. They support both simple operations and complex iterator expressions.

Example Usage

// Simple collection operation
let sizeExpr = ATLCollectionExpression(
    source: ATLVariableExpression(name: "items"),
    operation: .size
)

// Iterator-based operation
let selectExpr = ATLCollectionExpression(
    source: ATLVariableExpression(name: "numbers"),
    operation: .select,
    iterator: "n",
    body: ATLBinaryExpression(
        left: ATLVariableExpression(name: "n"),
        operator: .greaterThan,
        right: ATLLiteralExpression(value: 0)
    )
)
