API版本AnchorPane.topAnchor FXML属性？

Question

我想弄清楚JavaFX API调用等效于FXML AnchorPane.topAnchor（和底部，右侧，左侧锚点）属性。通常FXML属性似乎是对象的属性，但似乎没有一个AnchorPane类型属性或返回此类型对象的任何其他属性。

举例来说，如果我有以下FXML

<BorderPane fx:id="borderPane" AnchorPane.bottomAnchor="4.0" 
    AnchorPane.leftAnchor="4.0" 
    AnchorPane.rightAnchor="4.0" 
    AnchorPane.topAnchor="30.0"> .... more FXML here 

什么是相关的Java API调用设置anchorpane锚？

例如

BorderPane borderPane = new BorderPane(); 
// 
// What method calls on borderPane would set the anchors? 
// 

感谢您的任何指示。
