XBRL
is a "mutable state" function that offers a object-oriented
programming-like interface, by exposing "methods" that perform accions
on XBRL files. It keeps a list of data frames that are populated by
the "methods" by calls to the low-level functions (see
xbrlParse
).
The approach used is derived from an example included in *10.7 Scope*
of *An Introduction to R*. The employed terminology may be inaccurate,
hence the quotations. XBRL
"methods" are called by
xbrlDoAll
. See examples of use below.
