What does T mean when used as a method signature? Is it a return type?

Question

abstract public  T iterEdges(EdgeFun func, T accum);

This is for a multithreaded library for graphs. I am not asking for anything

Answer 1

It is a generic method. The first is for the generic type that would be used. The function is also declaring that is returns that type T. The parameters are showing that they use that generic parameter type.
