Member Function Documentation

◆ create()

static Glib::RefPtr< ZlibCompressor > Gio::ZlibCompressor::create	(	ZlibCompressorFormat	format,
		int	level
	)

static

Creates a new ZlibCompressor.

Since glibmm 2.24:

Parameters

format	The format to use for the compressed data.
level	Compression level (0-9), -1 for default.

Returns: A new ZlibCompressor.

◆ get_file_info() [1/2]

Glib::RefPtr< FileInfo > Gio::ZlibCompressor::get_file_info ( )

Returns the ZlibCompressor::property_file_info() property.

Since glibmm 2.26:

Returns: A FileInfo, or nullptr.

◆ get_file_info() [2/2]

Glib::RefPtr< const FileInfo > Gio::ZlibCompressor::get_file_info ( ) const

Returns the ZlibCompressor::property_file_info() property.

Since glibmm 2.26:

Returns: A FileInfo, or nullptr.

◆ get_type()

static GType Gio::ZlibCompressor::get_type ( )

static

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

◆ gobj() [1/2]

GZlibCompressor * Gio::ZlibCompressor::gobj ( )

inline

Provides access to the underlying C GObject.

◆ gobj() [2/2]

const GZlibCompressor * Gio::ZlibCompressor::gobj ( ) const

inline

Provides access to the underlying C GObject.

◆ gobj_copy()

GZlibCompressor * Gio::ZlibCompressor::gobj_copy ( )

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

◆ operator=()

ZlibCompressor & Gio::ZlibCompressor::operator= ( ZlibCompressor && src )

noexcept

◆ property_file_info() [1/2]

Glib::PropertyProxy< Glib::RefPtr< FileInfo > > Gio::ZlibCompressor::property_file_info ( )

If set to a non-nullptr FileInfo object, and ZlibCompressor::property_format() is ZLIB_COMPRESSOR_FORMAT_GZIP, the compressor will write the file name and modification time from the file info to the GZIP header.

Since glibmm 2.26:

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

◆ property_file_info() [2/2]

Glib::PropertyProxy_ReadOnly< Glib::RefPtr< FileInfo > > Gio::ZlibCompressor::property_file_info ( ) const

If set to a non-nullptr FileInfo object, and ZlibCompressor::property_format() is ZLIB_COMPRESSOR_FORMAT_GZIP, the compressor will write the file name and modification time from the file info to the GZIP header.

Since glibmm 2.26:

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

◆ property_format()

Glib::PropertyProxy_ReadOnly< ZlibCompressorFormat > Gio::ZlibCompressor::property_format ( ) const

The format of the compressed data.

Default value: ZLIB_COMPRESSOR_FORMAT_ZLIB

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

◆ property_level()

Glib::PropertyProxy_ReadOnly< int > Gio::ZlibCompressor::property_level ( ) const

The level of compression from 0 (no compression) to 9 (most compression), -1 for the default level.

Default value: -1

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

◆ set_file_info()

void Gio::ZlibCompressor::set_file_info ( const Glib::RefPtr< FileInfo > & file_info )

Sets file_info in compressor.

If non-nullptr, and compressor's ZlibCompressor::property_format() property is ZLIB_COMPRESSOR_FORMAT_GZIP, it will be used to set the file name and modification time in the GZIP header of the compressed data.

Note: it is an error to call this function while a compression is in progress; it may only be called immediately after creation of compressor, or after resetting it with g_converter_reset().

Since glibmm 2.26:

Parameters

file_info A FileInfo.

◆ wrap()

Glib::RefPtr< Gio::ZlibCompressor > wrap	(	GZlibCompressor *	object,
		bool	take_copy = `false`
	)

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.
