包路径：org.netbeans.editor.Utilities
类名称：Utilities
方法名：getIdentifierBlock

Utilities.getIdentifierBlock介绍

[英]Get the identifier around the given position or null if there's no identifier around the given position. The identifier is not verified against SyntaxSupport.isIdentifier().
[中]获取给定位置周围的标识符，如果给定位置周围没有标识符，则为null。未根据SyntaxSupport验证标识符。isIdentifier（）。
