DeclarationCollector

DeclarationCollector

A Swift syntax visitor that collects declarations.

open class DeclarationCollector:​ SyntaxVisitor

Create an instance of DeclarationCollector and pass it by reference when walking an AST created by SyntaxParser to collect any visited declarations:​

import SwiftSyntax
import SwiftSemantics

let source = #"enum E {}"#

var collector = DeclarationCollector()
let tree = try SyntaxParser.parse(source:​ source)
tree.walk(&collector)

collector.enumerations.first?.name // "E"
