"-function" special?

[ClusterCat]

Hi there,

in some clojure examples I see function names with a leading dash like
-main()
-getFoo() (in backing bean)
-setBar() (in backing bean)

Are these functions with leading dash anything special? Or is this dash
required for some interop?
I didn't find any documentation about it.

Thanks in advance,
Marcel

It's the default prefix for methods in classes generated by gen-class:

The leading dash is a convention in two places:

- gen-class methods implemented by Clojure functions (e.g. -main)

- low-level method implementations of built-in protocols in ClojureScript

The dash has no special significance as far as the compiler is concerned, it's just part of the name.
