Clear the current password used by the handler. Calling clearPassword() will disable the encryption/decryption of archives.
Note
This is equivalent to calling setPassword(L"").
const BitInOutFormat & compressionFormat() const noexcept
Returns the format used for creating/updating an archive.
BitCompressionLevel compressionLevel() const noexcept
Returns the compression level used for creating/updating an archive.
BitCompressionMethod compressionMethod() const noexcept
Returns the compression method used for creating/updating an archive.
Returns whether the creator crypts also the headers of archives or not.
Returns the dictionary size used for creating/updating an archive.
FileCallback fileCallback() const
Returns the current file callback.
[virtual] const BitInFormat &override format() const noexcept
Returns the format used for creating/updating an archive.
Returns a boolean value indicating whether a password is defined or not.
const Bit7zLibrary & library() const noexcept
Returns the Bit7zLibrary object used by the handler.
OverwriteMode overwriteMode() const
Returns the current OverwriteMode.
tstring password() const
Returns the password used to open, extract, or encrypt the archive.
PasswordCallback passwordCallback() const
Returns the current password callback.
ProgressCallback progressCallback() const
Returns the current progress callback.
RatioCallback ratioCallback() const
Returns the current ratio callback.
Returns a boolean value indicating whether the directory structure must be preserved while extracting or compressing the archive.
void setCompressionLevel( BitCompressionLevel level ) noexcept
Sets the compression level to be used when creating/updating an archive.
Parameters:
- level: the compression level desired.
void setCompressionMethod( BitCompressionMethod method )
Sets the compression method to be used when creating/updating an archive.
Parameters:
- method: the compression method desired.
Sets the dictionary size to be used when creating/updating an archive.
Parameters:
- dictionarySize: the dictionary size desired.
void setFileCallback( const FileCallback& callback )
Sets the function to be called when the current file being processed changes.
Parameters:
- callback: the file callback to be used.
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.
Parameters:
- name: The string name of the property to be set.
- value: The value to be used for the property.
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).
Parameters:
- name: The string name of the property to be set.
- value: The value to be used for the property.
void setOverwriteMode( OverwriteMode mode )
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.
[virtual] void setPassword( const tstring& password ) override
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).
Note
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.
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).
Note
Calling setPassword with "cryptHeaders" set to true does not have effects on formats different from 7z.
Note
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).
void setPasswordCallback( const PasswordCallback& callback )
Sets the function to be called when a password is needed to complete the ongoing operation.
Parameters:
- callback: the password callback to be used.
void setProgressCallback( const ProgressCallback& callback )
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.
void setRatioCallback( const RatioCallback& callback )
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.
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
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.
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.
Sets the number of threads to be used when creating/updating an archive.
Parameters:
- threadsCount: the number of threads desired.
void setTotalCallback( const TotalCallback& callback )
Sets the function to be called when the total size of an operation is available.
Parameters:
- callback: the total callback to be used.
Sets whether the creator can update existing archives or not.
Warning
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.
[virtual] void setUpdateMode( UpdateMode mode )
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.
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.
Sets the word size to be used when creating/updating an archive.
Parameters:
- wordSize: the word size desired.
Returns whether the archive creator uses solid compression or not.
Returns whether the archive creator stores symbolic links as links in the output archive.
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 totalCallback() const
Returns the current total callback.
UpdateMode updateMode() const noexcept
Returns the update mode used when updating existing archives.
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).
Returns the word size used for creating/updating an archive.
