Utilities.getDocument介绍

[英]Helper method to obtain instance of BaseDocument from JTextComponent. If the document of the component is not an instance of the org.netbeans.editor.BaseDocument the method returns null. The method doesn't require any document locking.
[中]帮助器方法从JTextComponent获取BaseDocument实例。如果组件的文档不是组织的实例。上网本。编辑BaseDocument方法返回null。该方法不需要任何文档锁定。
