ObjectStructure.S3: Class: ObjectStructure.S3

Description Usage Arguments Value Fields Intended use of this class Author(s) References See Also Examples

Class to represent object structures (S3).

1	ObjectStructure.S3(.x, struc = data.frame())

`.x`	`ANY`. An object of an arbitrary class whose class attribute should be updated so that it becomes an instance of class `ObjectStructure.S3`. Mainly intended for rapid prototyping purposes
`struc`	Constructor argument. See field `.struc`.

Instance of class ObjectStructure.S3.

.struc: data.frame. Object structure.

This S3 class, or to be more precise its constructor function, exists mainly for rapid prototyping purposes. This is mainly reflected in the fact, that when specifying .x, this constructor function will simply update the class attribute of whatever object has been provided.

However, it also allows for a more formal OOP-style of rapid prototyping by offering explicit class fields (all arguments except .x). Nevertheless, it is probably advisable to switch to an explicit formal approach such as S4 and/or Reference Classes once the package or application has reached a certain state of maturity.

## Not run: 

## Informal use (intended mainly for rapid prototyping) //
## Takes *any* object and simply changes the class attributes
ObjectStructure.S3(data.frame())  
ObjectStructure.S3("example of other input")  

## Formal use (explicitly using field constructor arguments) //
ObjectStructure.S3()
ObjectStructure.S3(struc = getStructure(list(a = 1, b = 2), extended = FALSE))

## Recommended: inlcude namespace //
listr::ObjectStructure.S3(
  struc = getStructure(list(a = 1, b = 2), extended = FALSE)
)
