noexcept

Sets the compression level to be used when creating/updating an archive.

Parameters

level the compression level desired.

◆ setCompressionMethod()

void setCompressionMethod ( BitCompressionMethod method )

Sets the compression method to be used when creating/updating an archive.

◆ setFormatProperty() [1/2]

template<std::size_t N, typename T , typename = typename std::enable_if< !std::is_integral< T >::value >::type>

void setFormatProperty	(	const wchar_t(&)	name[N],
		const T &	value
	)

inlinenoexcept

Sets a property for the output archive format as described by the 7-zip documentation (e.g., https://sevenzip.osdn.jp/chm/cmdline/switches/method.htm).

For example, passing the string L"tm" with a false value while creating a .7z archive will disable storing the last modified timestamps of the compressed files.

Template Parameters

T	A non-integral type (i.e., a string).

Parameters

name	The string name of the property to be set.
value	The value to be used for the property.

◆ setFormatProperty() [2/2]

template<std::size_t N, typename T , typename = typename std::enable_if< std::is_integral< T >::value >::type>

void setFormatProperty	(	const wchar_t(&)	name[N],
		T	value
	)

inlinenoexcept

Sets a property for the output archive format as described by the 7-zip documentation (e.g., https://sevenzip.osdn.jp/chm/cmdline/switches/method.htm).

Template Parameters

T	An integral type (i.e., a bool or an integer type).

Parameters

name	The string name of the property to be set.
value	The value to be used for the property.

◆ setOverwriteMode()

void setOverwriteMode ( OverwriteMode mode )

inherited

Sets how the handler should behave when it tries to output to an existing file or buffer.

Parameters

mode	the OverwriteMode to be used by the handler.

◆ setPassword() [1/2]

void setPassword ( const tstring & password )

overridevirtual

Sets up a password for the output archives.

When setting a password, the produced archives will be encrypted using the default cryptographic method of the output format. The option "crypt headers" remains unchanged, in contrast with what happens when calling the setPassword(tstring, bool) method.

Note: Calling setPassword when the output format doesn't support archive encryption (e.g., GZip, BZip2, etc...) does not have any effects (in other words, it doesn't throw exceptions, and it has no effects on compression operations).; After a password has been set, it will be used for every subsequent operation. To disable the use of the password, you need to call the clearPassword method (inherited from BitAbstractArchiveHandler), which is equivalent to setPassword(L"").

Parameters

password the password to be used when creating/updating archives.

Reimplemented from BitAbstractArchiveHandler.

◆ setPassword() [2/2]

void setPassword	(	const tstring &	password,
		bool	cryptHeaders
	)

Sets up a password for the output archive.

When setting a password, the produced archive will be encrypted using the default cryptographic method of the output format. If the format is 7z, and the option "cryptHeaders" is set to true, the headers of the archive will be encrypted, resulting in a password request every time the output file will be opened.

Note: Calling setPassword when the output format doesn't support archive encryption (e.g., GZip, BZip2, etc...) does not have any effects (in other words, it doesn't throw exceptions, and it has no effects on compression operations).; Calling setPassword with "cryptHeaders" set to true does not have effects on formats different from 7z.; After a password has been set, it will be used for every subsequent operation. To disable the use of the password, you need to call the clearPassword method (inherited from BitAbstractArchiveHandler), which is equivalent to setPassword(L"").

Parameters

password	the password to be used when creating/updating archives.
cryptHeaders	if true, the headers of the output archives will be encrypted (valid only when using the 7z format).

◆ setPasswordCallback()

void setPasswordCallback ( const PasswordCallback & callback )

inherited

Sets the function to be called when a password is needed to complete the ongoing operation.

Parameters

callback the password callback to be used.

◆ setProgressCallback()

void setProgressCallback ( const ProgressCallback & callback )

inherited

Sets the function to be called when the processed size of the ongoing operation is updated.

Note: The completion percentage of the current operation can be obtained by calculating static_cast<int>((100.0 * processed_size) / total_size).

Parameters

callback the progress callback to be used.

◆ setRatioCallback()

void setRatioCallback ( const RatioCallback & callback )

inherited

Sets the function to be called when the input processed size and current output size of the ongoing operation are known.

Note: The ratio percentage of a compression operation can be obtained by calculating static_cast<int>((100.0 * output_size) / input_size).

Parameters

callback the ratio callback to be used.

◆ setRetainDirectories()

void setRetainDirectories ( bool retain )

noexceptinherited

Sets whether the operations' output will preserve the input's directory structure or not.

Parameters

retain the setting for preserving or not the input directory structure

◆ setSolidMode()

void setSolidMode ( bool solidMode )

noexcept

Sets whether to use solid compression or not.

Note: Setting the solid compression mode to true has effect only when using the 7z format with multiple input files.

Parameters

solidMode if true, it will be used the "solid compression" method.

◆ setStoreSymbolicLinks()

void setStoreSymbolicLinks ( bool storeSymlinks )

noexcept

Sets whether the creator will store symbolic links as links in the output archive.

Parameters

storeSymlinks if true, symbolic links will be stored as links.

◆ setThreadsCount()

void setThreadsCount ( uint32_t threadsCount )

noexcept

Sets the number of threads to be used when creating/updating an archive.

Parameters

threadsCount the number of threads desired.

◆ setTotalCallback()

void setTotalCallback ( const TotalCallback & callback )

inherited

Sets the function to be called when the total size of an operation is available.

Parameters

callback the total callback to be used.

◆ setUpdateMode() [1/2]

void setUpdateMode ( bool canUpdate )

Sets whether the creator can update existing archives or not.

Deprecated:: since v4.0; it is provided just for an easier transition from the old v3 API.

Note: If set to false, a subsequent compression operation may throw an exception if it targets an existing archive.

Parameters

canUpdate if true, compressing operations will update existing archives.

◆ setUpdateMode() [2/2]

virtual void setUpdateMode ( UpdateMode mode )

virtual

Sets whether and how the creator can update existing archives or not.

Note: If set to UpdateMode::None, a subsequent compression operation may throw an exception if it targets an existing archive.

Parameters

mode	the desired update mode.

Reimplemented in BitArchiveEditor.

◆ setVolumeSize()

void setVolumeSize ( uint64_t volumeSize )

noexcept

Sets the volumeSize (in bytes) of the output archive volumes.

Note: This setting has effects only when the destination archive is on the filesystem.

Parameters

volumeSize The dimension of a volume.

◆ setWordSize()

void setWordSize ( uint32_t wordSize )

Sets the word size to be used when creating/updating an archive.

Parameters

wordSize the word size desired.

auto solidMode ( ) const -> bool

noexcept

Returns: whether the archive creator uses solid compression or not.

noexcept

Returns: whether the archive creator stores symbolic links as links in the output archive.

◆ threadsCount()

auto threadsCount ( ) const -> uint32_t

noexcept

Returns: the number of threads used when creating/updating an archive (a 0 value means that it will use the 7-zip default value).

◆ totalCallback()

auto totalCallback ( ) const -> TotalCallback

inherited

Returns: the current total callback.

◆ updateMode()

auto updateMode ( ) const -> UpdateMode

noexcept

Returns: the update mode used when updating existing archives.

◆ volumeSize()

auto volumeSize ( ) const -> uint64_t

noexcept

Returns: the volume size (in bytes) used when creating multi-volume archives (a 0 value means that all files are going in a single archive).

◆ wordSize()

auto wordSize ( ) const -> uint32_t

noexcept

Returns: the word size used for creating/updating an archive.
