Members

private

• $archiveHeaderData
• $password

protected

• $_errors_queue_size — array
• $_parametersArray — array
  Any configuration variables, in the form of an array.
• $_warnings_queue_size — array
• $active_domain — string
  The name of the engine part (a.k.a. Domain), used in return table generation.
• $active_step — string
  The step this engine part is in. Used verbatim in return table and should be set by the code in the _run() method.
• $active_substep — string
  A more detailed description of the step this engine part is in. Used verbatim in return table and should be set by the code in the _run() method.
• $addPath — string
• $chunkSize — integer
• $currentPartNumber — integer
• $currentPartOffset — integer
• $dataReadLength — int
• $databaseRoot — string
• $fileHeader — stdClass
• $filename — string
• $flagRestorePermissions — bool
• $fp — resource
• $hasRan — boolean
  Indicates whether this part has finished its run cycle
• $isFinished — boolean
  Indicates whether this part has finished its finalization cycle
• $isPrepared — boolean
  Indicates whether this part has finished its initialisation cycle
• $isRunning — boolean
  Indicates whether this part has more work to do (it's in running state)
• $observers — array
• $postProcEngine — AKAbstractPostproc
• $runState — int

public

• $archiveList — array
• $renameDirs — array
• $renameFiles — array
• $skipFiles — array
• $totalSize — int

Methods

private

• processTypeDir() — Process the file data of a directory entry
• processTypeFileCompressedSimple()
• processTypeFileUncompressed()
• processTypeLink() — Process the file data of a link entry

protected

• createDirectory() — Creates the directory this file points to
• processFileData() — Concrete classes must use this method to process file data. It must set $runState to AK_STATE_DATAREAD when it's finished processing the file data.
• readArchiveHeader()
• readFileHeader() — Concrete classes must use this method to read the file header

Inherited from AKUnarchiverJPA

protected

• createDirectory() — Creates the directory this file points to
• processFileData() — Concrete classes must use this method to process file data. It must set $runState to AK_STATE_DATAREAD when it's finished processing the file data.
• readArchiveHeader()
• readFileHeader() — Concrete classes must use this method to read the file header

Inherited from AKAbstractUnarchiver

protected

• _finalize()
• _prepare() — Implements the abstract _prepare() method
• _run()
• fread() — Reads data from the archive and notifies the observer with the 'reading' message
• isEOF() — Returns true if we have reached the end of file
• nextFile() — Opens the next part file for reading
• processFileData() — Concrete classes must use this method to process file data. It must set $runState to AK_STATE_DATAREAD when it's finished processing the file data.
• readArchiveHeader() — Concrete classes are supposed to use this method in order to read the archive's header and prepare themselves to the point of being ready to extract the first file.
• readFileHeader() — Concrete classes must use this method to read the file header
• setCorrectPermissions() — Tries to make a directory user-writable so that we can write a file to it

public

• __wakeup() — Wakeup function, called whenever the class is unserialized
• shutdown() — Sleep function, called whenever the class is serialized

Inherited from AKAbstractPart

protected

• _finalize() — Runs the finalisation process for this part. Should set _isFinished to true.
• _makeReturnTable() — Constructs a Response Array based on the engine part's state.
• _prepare() — Runs the preparation for this part. Should set _isPrepared to true
• _run() — Runs the main functionality loop for this part. Upon calling, should set the _isRunning to true. When it finished, should set the _hasRan to true. If an error is encountered, setError should be used.
• notify() — Notifies observers each time something interesting happened to the part
• setBreakFlag() — Sets the BREAKFLAG, which instructs this engine part that the current step must break immediately, in fear of timing out.
• setDomain()
• setState() — Sets the engine part's internal state, in an easy to use manner
• setStep()
• setSubstep()

public

• attach() — Attaches an observer object
• detach() — Dettaches an observer object
• getDomain()
• getState() — Returns the state of this engine part.
• getStatusArray() — Returns a copy of the class's status array
• getStep()
• getSubstep()
• setup() — Sends any kind of setup information to the engine part. Using this, we avoid passing parameters to the constructor of the class. These parameters should be passed as an indexed array and should be taken into account during the preparation process only. This function will set the error flag if it's called after the engine part is prepared.
• tick() — The public interface to an engine part. This method takes care for calling the correct method in order to perform the initialisation - run - finalisation cycle of operation and return a proper reponse array.

Inherited from AKAbstractObject

protected

• setErrorsQueueSize() — Sets the size of the error queue (acts like a LIFO buffer)
• setWarningsQueueSize() — Sets the size of the warnings queue (acts like a LIFO buffer)

public

• getError() — Get the most recent error message
• getErrors() — Return all errors, if any
• getWarning() — Get the most recent warning message
• getWarnings() — Return all warnings, if any
• propagateFromObject() — Propagates errors and warnings from a foreign object. Each propagated list is then cleared on the foreign object, as long as it implements resetErrors() and/or resetWarnings() methods.
• propagateToObject() — Propagates errors and warnings to a foreign object. The foreign object SHOULD implement the setError() and/or setWarning() methods but DOESN'T HAVE TO be of AKAbstractObject type. For example, this can even be used to propagate to a JObject instance in Joomla!. Propagated items will be removed from ourself.
• resetErrors() — Resets all error messages
• resetWarnings() — Resets all warning messages
• setError() — Add an error message
• setWarning() — Add an error message
