Class Nodes::ClassNode

A data flow node corresponding to a class definition or a function definition acting as a class.

The following patterns are recognized as classes and methods:

class C {
  method()
}

function F() {}

F.prototype.method = function() {}

F.prototype = {
  method: function() {}
}

extend(F.prototype, {
  method: function() {}
});

Additional patterns can be recognized as class nodes, by extending DataFlow::ClassNode::Range.
