如何显式调用对象的init块？

Question

object MyClass {
    var editor: Editor = getDefaultEditor()
        set(value) {
            field = value

            //Todo: figure out how to avoid duplicating init block
            project = editor.project!!
            document = editor.document.charsSequence.toString().toLowerCase()
            findModel = FindManager.getInstance(project).findInFileModel.clone()
            findManager = FindManager.getInstance(project)
        }

    var project: Project
    var document: String
    var findModel: FindModel
    var findManager: FindManager

    init {
        project = editor.project!!
        document = editor.document.charsSequence.toString().toLowerCase()
        findModel = FindManager.getInstance(project).findInFileModel.clone()
        findManager = FindManager.getInstance(project)
    }
}

Answer 1

您可以使用lateInit对编译器说“稍后我将初始化该属性”。

lateinit var project: Project
lateinit var document: String
lateinit var findModel: FindModel
lateinit var findManager: FindManager

然后，可以在init块中省略初始化，并随时进行。
