Object-oriented approach

The {esqlabsR} package utilizes the concept of object-oriented (OO) programming based on the R6 system. While the philosophy of the package is to offer a functional programming workflow more common for the R users, it is important to understand some basic concepts of the OO programming. Many of the functions implemented in {esqlabsR} return an instance (or an object) of a class. These objects can be used as inputs for other methods. Additionally, each object offers a set of properties (which can be other objects) and methods, which are accessible by the $ character:

# create an instance of an object
object1 <- ClassName$new()

# extract a property associated with this object
aProperty <- object1$property1

# apply a method associated with this object
resultOfAFunction <- object1$multiply(1,2)

Important information about the object can be printed out by calling print(object).
