Detailed Description

template<typename _Tp, typename _CharT = char, typename _Traits = std::char_traits<_CharT>, typename _Dist = ptrdiff_t>
class rpa::istream_iterator_delimiter< _Tp, _CharT, _Traits, _Dist >

Provides input iterator semantics for streams. Equivalent to istream_iterator, but with an arbitrary delimiter. Can be of general purpose, but used here for tests only. NOTE: When buffering the input, it would be extremely fine to avoid an extra copy and storage of the data type. See member _M_value.

[inline]

Construct end of input stream iterator.

rpa::istream_iterator_delimiter< _Tp, _CharT, _Traits, _Dist >::istream_iterator_delimiter	(	istream_type &	__s,
		const char_type *	aDelim
	)			[inline]

Construct start of input stream iterator. If the delimiter is NULL, we assume an empty string.

void rpa::istream_iterator_delimiter< _Tp, _CharT, _Traits, _Dist >::_M_read

(

)

[inline, private]

Does the same as for a plain std::istream_iterator, but after the value is read, it attemps to read the delimiter, and fails if it is not there.

Now reads the delimiter if there is one. If we cannot read a full delimiter, the iterator is left as invalid.

This indicates the end of stream.
