Constructor & Destructor Documentation

string_writer() [1/2]

xtd::io::string_writer::string_writer ( )

default

Initializes a new instance of the stream_writer class .

string_writer() [2/2]

xtd::io::string_writer::string_writer ( const xtd::string &  str )

explicit

Initializes a new instance of the stream_writer class for the specified string.

Parameters

str	base string.

Member Function Documentation

base_stream() [1/2]

const std::ostream & xtd::io::string_writer::base_stream ( ) const

noexcept

Returns the underlying stream.

Returns

The underlying stream.

base_stream() [2/2]

std::ostream & xtd::io::string_writer::base_stream ( )

noexcept

Returns the underlying stream.

Returns

The underlying stream.

flush()

void xtd::io::string_writer::flush ( )

overridevirtual

Clears all buffers for the current writer and causes any buffered data to be written to the underlying device.

Remarks

This default method does nothing, but derived classes can virtual the method to provide the appropriate functionality

Reimplemented from xtd::io::text_writer.

to_string()

xtd::string xtd::io::string_writer::to_string ( ) const

overridevirtualnoexcept

Returns a xtd::string that represents the current object.

Returns

A string that represents the current object.

Examples

The following code example demonstrates what to_string returns.

#include <xtd/xtd>
 
using namespace xtd;
 
namespace examples {
  namespace object_test {
    class object1 : public object {
    };
  }
}
 
auto main() -> int {
  ptr<object> obj1 = new_ptr<examples::object_test::object1>();
  console::write_line(obj1->to_string());
 
  ptr<object> obj2 = new_ptr<date_time>(1971, 1, 5, 23, 5, 0);
  console::write_line(obj2->to_string());
 
  ptr<object> obj3 = new_ptr<boolean_object>();
  console::write_line(obj3->to_string());
}
 
// This code produces the following output :
//
// examples::object_test::object1
// Tue Jan  5 23:05:00 1971
// false

Reimplemented from xtd::object.

write()

void xtd::io::string_writer::write ( const xtd::string &  value )

overridevirtual

Writes the specified string value to the text stream.

Parameters

value

The value to write

Exceptions

io::io_exception

An I/O error occurs.

Reimplemented from xtd::io::text_writer.
