Although RFC 4627 requires root elements to be either an object or an
array, sometimes the plain (de)serialisation of an arbitrary value is
needed.
This patch adds a new function AcceptAnyRoot(bool) to
* GenericReader
* GenericDocument
* (Pretty)Writer
to optionally accept such arbitrary root elements for reading/parsing
and writing.
Example:
{
Document d;
d.AcceptAnyRoot().Parse<0>( "\"foo\"" );
assert(!d.HasParseError());
assert(d.IsString());
FileStream s(stdout);
PrettyWriter<FileStream> writer(s);
d.Accept( writer.AcceptAnyRoot() );
}
This functionality is guarded behind the preprocessor symbol
RAPIDJSON_ACCEPT_ANY_ROOT.
And consistently add documentation to all AcceptAnyRoot() functions.
