Function Documentation

std::string zypp::iostr::getline

(

std::istream &

str

)

Read one line from stream.

Reads everything up to the next newline or EOF. newline is read but not returned.

forEachLine

Definition at line 31 of file IOStream.cc.

std::ostream& zypp::iostr::copy	(	std::istream &	from_r,
		std::ostream &	to_r
	)		[inline]

Copy istream to ostream.

Returns:

reference to the ostream.

Definition at line 49 of file IOStream.h.

std::ostream& zypp::iostr::copyIndent	(	std::istream &	from_r,
		std::ostream &	to_r,
		const std::string &	indent_r = "> "
	)		[inline]

Copy istream to ostream, prefixing each line with indent_r (default "> " ).

Returns:

reference to the ostream.

Definition at line 63 of file IOStream.h.

void zypp::iostr::tee	(	std::istream &	from_r,
		std::ostream &	to1_r,
		std::ostream &	to2_r
	)		[inline]

Copy istream to ostream, prefixing each line with indent_r (default "> " ).

Returns:

reference to the ostream.

Definition at line 83 of file IOStream.h.

template<class _Function >

_Function& zypp::iostr::forEachLine	(	std::istream &	str_r,
		_Function &	consume_r
	)

Simple lineparser: Call functor consume_r for each line.

Parameters:

str_r	The istream to read from.
consume_r	A reference to a function or functor. The loop is aborted if the function returns false. bool consume( const std::string & ) { ... } struct Consume : public std::unary_function<const std::string &, bool> { bool operator()( const std::string & line_r ) { ... } };

Returns:

A reference to consume_r.

Todo:

Should be templated and specialized according to the functors return type, to allow void consumer.
