class BitArchiveHandler
Description
Abstract class representing a generic archive handler.
Inheritance
Decsendents: BitArchiveOpener, BitArchiveCreator
Methods
| BitArchiveHandler | ||
| ~BitArchiveHandler | ||
| clearPassword | Clear the current password used by the handler. | |
| fileCallback | Return the current file callback. | |
| format | Return the format used by the handler for extracting or compressing. | |
| isPasswordDefined | Return true if a password is defined, false otherwise. | |
| library | Return the Bit7zLibrary object used by the handler. | |
| password | Return the password used to open, extract or encrypt the archive. | |
| passwordCallback | Return the current password callback. | |
| progressCallback | Return the current progress callback. | |
| ratioCallback | Return the current ratio callback. | |
| setFileCallback | Sets the callback to be called when the currently file being processed changes. | |
| setPassword | Sets up a password to be used by the archive handler. | |
| setPasswordCallback | Sets the callback to be called when a password is needed to complete the ongoing operation. | |
| setProgressCallback | Sets the callback to be called when the processed size of the ongoing operation is updated. | |
| setRatioCallback | Sets the callback to be called when the input processed size and current output size of the ongoing operation are known. | |
| setTotalCallback | Sets the callback to be called when the total size of an operation is available. | |
| totalCallback | Return the current total callback. |

* the extraction process.
*
* @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, which is equivalent
* to call setPassword(L"").
*
* @param password the password to be used.
