CSSStatement-class: Class "CSSStatement"

In omegahat/RCSS: Facilities for reading and working with CSS files in R

Description

This is the basic class for representing an internal C-level CSS element. We can query certain elements within such objects directly or we can convert such an object to an S4 object that is equivalent. We use asCSSObject to perform this C-to-R conversion.

Objects from the Class

Objects of this and related sub-classes are created implicitly via accessing elements of a CSSStyleSheet-class object, e.g. using [[ and [ methods.

Slots

ref:

Object of class "externalptr" which holds the reference to the C object.

Extends

Class "ExternalRef", directly.
