DeclarationCollector

DeclarationCollector

A Swift syntax visitor that collects declarations.

open class DeclarationCollector

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"

Initializers

init()

Creates a new declaration collector.
