XPathContextMajor.setStackFrame介绍

[英]Set the local stack frame. This method is used when creating a Closure to support delayed evaluation of expressions. The "stack frame" is actually on the Java heap, which means it can survive function returns and the like.
[中]设置本地堆栈帧。创建闭包以支持表达式的延迟求值时使用此方法。“堆栈框架”实际上位于Java堆上，这意味着它可以在函数返回等情况下存活。
