API版本AnchorPane.topAnchor FXML屬性？

Question

我想弄清楚JavaFX API調用等效於FXML AnchorPane.topAnchor（和底部，右側，左側錨點）屬性。通常FXML屬性似乎是對象的屬性，但似乎沒有一個AnchorPane類型屬性或返回此類型對象的任何其他屬性。

舉例來說，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 

什麼是相關的Java API調用設置anchorpane錨？

例如

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

感謝您的任何指示。
