java. context.getFormattedValue() and context.webRoot() methods: what they do?

check the code of one of the applications, and found this line:

out.print(con开发者_运维技巧text.getFormattedValue(context.webRoot(),null)); 

I tried to find a description of methods with Google:

context.webRoot()
context.getFormattedValue()

but I could not find the official description of these methods. Why?

This is what that very specific methods? This outdated methods?

"context" in your code is an object; you need to figure out the class of that object. For example, HttpServlet has a "ServletContext" object which maintains the context for the servlet. Your code probably has something that declares "context" as a specific Java type--once you know that, then you can do your web search on "ObjectClassname.webRoot()" and have some hope of figuring out what's going on.
