Complaining, just post the object after inspecting it and ask directly, you are really lazy

You didn’t say what library you used. If there is a library and there is documentation, look at the documentation. If there is no documentation, look at the source code
There is no context as to how your object was created

About the question
The information you obtained seems to be in the @info instance variable
