#include <CGAL/IO/Indenting_ostream.h>

Inherits from

std::basic_streambuf< CharT, std::char_traits< CharT > >, and std::char_traits< CharT >.

Definition

template<typename CharT, typename Traits = std::char_traits<CharT>>
class CGAL::IO::Basic_indenting_streambuf< CharT, Traits >

The class template Basic_indenting_streambuf wraps another basic_streambuf and automatically adds indentation at the beginning of each line.

This is useful for formatting debug output with consistent indentation levels.

Template Parameters

CharT	Character type (typically `char` or `wchar_t`)
Traits	Character traits type

Public Types
using	char_type = CharT
	Character type.

using	traits_type = Traits
	Character traits type.

using	int_type = typename traits_type::int_type
	Integer type for character representation.

using	pos_type = typename traits_type::pos_type
	Position type for stream positioning.

using	off_type = typename traits_type::off_type
	Offset type for stream positioning.

using	streambuf_type = std::basic_streambuf< char_type, traits_type >
	Type of the wrapped streambuf.

using	string = std::basic_string< char_type >
	String type matching character type.

Public Member Functions
	Basic_indenting_streambuf (streambuf_type &wrapped_buf, const string &indent_string={2, char_type(' ')})
	constructs an indenting streambuf wrapper.

const string &	indent_string () const
	gets the current indentation string.

void	set_indent_string (const string &new_indent)
	sets a new indentation string.

void	set_indent_level (int level, int spaces_per_level=2)
	sets indentation level using repeated spaces.

streambuf_type &	wrapped_streambuf () const
	gets the wrapped streambuf.

	)

sets indentation level using repeated spaces.

Parameters

level	Number of indentation levels
spaces_per_level	Number of spaces per level (default: 2)

Parameters
