ATLTargetPattern

struct ATLTargetPattern

Overview

Target patterns define the output specifications for both matched and called rules. They specify the type of target elements to create, variable binding for reference within the rule, and property bindings that define the relationships and values for the created elements.

Overview

Target patterns support several key features:

• Element creation: Automatic instantiation of target metamodel elements

• Property binding: Declarative specification of property values

• Reference resolution: Automatic handling of cross-references and containment

• Variable scoping: Local variables accessible to other patterns and expressions

Example Usage

let personPattern = ATLTargetPattern(
    variableName: "targetPerson",
    type: "Persons!Person",
    bindings: [
        "fullName": ATLVariableExpression(name: "s.firstName"),
        "gender": ATLHelperCallExpression(helperName: "determineGender", arguments: [])
    ]
)
