what '< >' means in c++?

I have a tiny question, probably an easy one, but I couldn't found googling it. I am working on some code that has something like that:

Inserter::Inserter(const data::Set& set){
produces<Info>();
}

I don't quite understand what produces means or I am doing something wrong. Here is my interpretation, PLEASE correct me if I am said something wrong:

I had a class Inserter that had an Inserter object, calling from a constant of the object set of class data. Then I produces another object called Info.

am I right?. Please I need some help!!!

Generics :)

Aka "templates"

I had a class Inserter that had an Inserter object, calling from a constant of the object set of class data. Then I produces another object called Info.

Kind of :)

You have a class "Inserter".

It's constructor uses a template class "producer". You instantiate an "Info" kind of "producer".

Here's a good tutorial on templates:

They surround a template type.

produces is either a function or a class which is templated. The function, or a default constructor, is called.

The specific meaning depends on the implementation. You should read up on how templates work; it is much too involved for a SO answer.
