The central component of the library is the basic_ptree
class template. Instances of this class are property trees. It is parametrized
on key and data type, and key comparison policy; ptree
,
wptree
, iptree
and wiptree
are typedefs of basic_ptree
using predefined combinations of template parameters. Property tree is basically
a somewhat simplified standard container (the closest being std::list), plus
a bunch of extra member functions. These functions allow easy and effective
access to the data stored in property tree. They are various variants of get
, put
, get_value
,
put_value
,
get_child
,
put_child
.
Additionally, there is a data
function to access node data directly.
