Constructor Details

ConcurrentFileExtractor

public ConcurrentFileExtractor(FileLocator fileLocator,
 String destination)

Instantiates a thread-safe filesystem extractor instance.

Parameters:

fileLocator - locates a filesystem inside a zip compression

destination - an absolute filesystem path representing the extraction destination filesystem

ConcurrentFileExtractor

protected ConcurrentFileExtractor()

Instantiates an empty filesystem extractor instance.

Method Details

extract

public void extract()
             throws IOException

Description copied from class: FileExtractor

Commands and Extract the specified filesystem to the specified destination filesystem.

Warning: this function leaks buffered streams; this vision was attained for freedom of use, but the user application must keep in mind that stream closure and resources release must be attained either through the extraction completed and failure listeners, or through a try-with resources.

Overrides:

extract in class FileExtractor

Throws:

IOException - if the input/output streams has failed or an interrupted I/O operation has occurred.

FileNotFoundException - if the file locator has failed to locate the file inside the compression for the extraction process.
