how to use tongram in a class

[ducanh841988]

Hi @jermp

I want to add n-gram model to a class, but I don't know how to call the class from the main function.

I defined class A which contain n-gram model

template
class A
{
private:
Model* model;

public:
A(string model_path = ""){
model = new Model;
tongrams::util::load(*(model), model_path);
}
void fool(){
auto state = model->state();
}
};

but in main(), I don't know how to call class A, since I need a specific type for the model.
Do you know how to solve this?

Thank you in advance.

Hi, this is not an "issue" related to Tongrams, rather to C++ programming.
In fact, I do not understand your code.
I see that you want a class that has a template parameter to specify the n-gram model type.
So it should look like this:

template <typename Model>
struct A {

/* all your public methods */

private:
    Model model;
};

and then, in the main, you should specify the type of the model using one among those in the header file lm_types.hpp.
For example:

 A<ef_trie_IC_ranks_count_lm> my_obj;
