Class Public::MethodCallNode
A data flow node that represents a direct call to a method.
When a method value is assigned to a variable then when it is called it syntactically looks like a function call, as in the following example.
file, _ := os.Open("test.txt")
f := file.Close
f()
In this case it will not be considered a MethodCallNode.
