# MethodSourceInfo

This object is used by Loupe JavaScript agents to record information about where a message is being logged from.

## Definition

The object is very simple:

```
MethodSourceInfo {
    file;
    method;
    line;
    column
}
```

## Creation

To make it easier to use this the `loupe` namespace has a constructor function on it allowing you
to create a new one by calling `new` against it providing parameters for the information e.g. 

```
var methodSourceInfo = new loupe.MethodSourceInfo('app.js','init',10,1);
```
