Question

Often when looking at method calls with many parameters, I’d like to know what a particular parameter’s Javadoc without counting the number of commas, then going to the declaration and counting again.

How can I directly view the Javadoc for a particular parameter from the client method call?

Answer 1

Eclipse does not support this, and I’ve filed an enhancement request.

Suppose I have the following code:

void foo(int i) {}
void bar() {
   foo(1);
}

If I hover over the 1, I would like to see “int i” as I do if I hover
over “foo”. I know this can conflict with showing the Javadocs of
methods or fields in the parameter such as how presently Eclipse shows
on hover the Javadoc for random() below:

void bar() {
   foo(random());
}

Perhaps there could be a hover modifier key to override this and a
precedence order to determine which Javadoc is displayed in this case.
