Detailed Description

ZlibCompressor - Zlib compressor.

ZlibCompressor is an implementation of Converter that compresses data using zlib.

Since glibmm 2.34:

Member Function Documentation

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

Creates a new ZlibCompressor.

Since glibmm 2.24:
Parameters
formatThe format to use for the compressed data.
levelCompression level (0-9), -1 for default.
Returns
A new ZlibCompressor.
Glib::RefPtr<FileInfo> Gio::ZlibCompressor::get_file_info ( )

Returns the ZlibCompressor::property_file_info() property.

Since glibmm 2.26:
Returns
A FileInfo, or nullptr.
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.
static GType Gio::ZlibCompressor::get_type ( )
static

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

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

Provides access to the underlying C GObject.

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

Provides access to the underlying C GObject.

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.

ZlibCompressor& Gio::ZlibCompressor::operator= ( ZlibCompressor&&  src)
noexcept
Glib::PropertyProxy< Glib::RefPtr<FileInfo> > Gio::ZlibCompressor::property_file_info ( )

If set to a non-nullptr FileInfo object, and ZlibCompressor::property_format() is Gio::ZlibCompressorFormat::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.
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 Gio::ZlibCompressorFormat::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.
Glib::PropertyProxy_ReadOnly< ZlibCompressorFormat > Gio::ZlibCompressor::property_format ( ) const

The format of the compressed data.

Default value: Gio::ZlibCompressorFormat::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.
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.
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 Gio::ZlibCompressorFormat::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_infoA FileInfo.
