result_type pni::io::nx::begin_visitor< GTYPE, FTYPE, ATYPE, LTYPE >::operator() ( const field_type &  ) const

Throws type_error as fields do not have children over which we can iterate.

Exceptions

type_error

in any case

Parameters

f	field instance

Returns

to be ignored

template<typename GTYPE , typename FTYPE , typename ATYPE , typename LTYPE >

result_type pni::io::nx::begin_visitor< GTYPE, FTYPE, ATYPE, LTYPE >::operator() ( const attribute_type &  ) const

inline

Throws type_error - an attribute does not have an interator.

Exceptions

type_error

in any case

Parameters

a	attribute instance

Returns
