类名称：Node
方法名：getEncapsulatingSourceSection

Node.getEncapsulatingSourceSection介绍

[英]Retrieves the segment of guest language source code that is represented by this Node, if present; otherwise retrieves the segment represented by the nearest AST ancestor that has this information. Can be called on any thread and without a language context.
[中]检索此节点表示的来宾语言源代码段（如果存在）；否则，检索由具有此信息的最近AST祖先表示的段。可以在任何线程上调用，无需语言上下文。
