类名称：YangFunctionCallExpr

YangFunctionCallExpr介绍

[英]Function call invocation. Function names without a prefix are mapped into YangConstants#RFC6020_YIN_MODULE, as they are required to be mapped into YANG as per RFC7950 definitions.
[中]函数调用。没有前缀的函数名被映射到YangConstants#RFC6020_YIN_模块，因为根据RFC7950的定义，它们需要映射到YANG。
