## Detailed Description

ConverterOutputstream - Converter Output Stream.

Converter output stream implements OutputStream and allows conversion of data of various types during reading. ConverterOutputStream also implements the PollableOutputStream interface.

Since glibmm 2.34:

static Glib::RefPtr<ConverterOutputStream> Gio::ConverterOutputStream::create | ( | const Glib::RefPtr< OutputStream >& | base_stream,
|  | const Glib::RefPtr< Converter >& | converter
| ) |  |

static

Creates a new converter output stream for the base_stream.

Parameters

  base_stream | A OutputStream.
  converter | A Converter.

Returns
  A new OutputStream.

Glib::RefPtr<Converter> Gio::ConverterOutputStream::get_converter | ( |  | ) |

Gets the Converter that is used by converter_stream.

Since glibmm 2.24:

Returns
  The converter of the converter output stream.

Glib::RefPtr<const Converter> Gio::ConverterOutputStream::get_converter | ( |  | ) | const

Gets the Converter that is used by converter_stream.

Since glibmm 2.24:

Returns
  The converter of the converter output stream.

static GType Gio::ConverterOutputStream::get_type | ( |  | ) |

static

Get the GType for this class, for use with the underlying GObject type system.

GConverterOutputStream* Gio::ConverterOutputStream::gobj | ( |  | ) |

inline

Provides access to the underlying C GObject.

const GConverterOutputStream* Gio::ConverterOutputStream::gobj | ( |  | ) | const

inline

Provides access to the underlying C GObject.

GConverterOutputStream* Gio::ConverterOutputStream::gobj_copy | ( |  | ) |

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

Glib::PropertyProxy_ReadOnly< Glib::RefPtr<Converter> > Gio::ConverterOutputStream::property_converter | ( |  | ) | const

The converter object.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

related

A Glib::wrap() method for this object.

Parameters

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns
  A C++ instance that wraps this C instance.
