struct ATLExpressionXMISerializer

Overview

This serializer converts expression trees into the standard Eclipse ATL XMI representation, following the OCL metamodel structure defined in the ATL specification.

Expression Types Supported

Literals: Integer, string, boolean, and null literals
Variables: Variable references
Navigation: Property and feature navigation
Operations: Binary, unary, and method call operations
Collections: Collection literals and operations
Control Flow: Conditional (if-then-else) expressions
Advanced: Let expressions, lambda expressions, iterate expressions

XMI Format

Expressions are serialized with xsi:type attributes to distinguish types:

<expression xsi:type="ocl:VariableExp" varName="sourceElement"/>
<expression xsi:type="ocl:OperationCallExp" operationName="concat">
  <source xsi:type="ocl:VariableExp" varName="firstName"/>
  <arguments xsi:type="ocl:StringExp" stringSymbol="..."/>
</expression>
