Constructor Details

LibraryExtractor

public LibraryExtractor(ZipFile compression,
 String libraryPath,
 String destination)
                 throws IOException

Instantiates a native dynamic library extractor for an external compression file locator routine.

Parameters:

compression - the zip file object for external locator routines

libraryPath - the path of the library inside the compression filesystem

destination - the extraction destination filesystem path

Throws:

IOException - if the jar filesystem to be located is not found, or if the extraction destination is not found

LibraryExtractor

public LibraryExtractor(String libraryPath,
 String destination)

Instantiates a native dynamic library extractor with a library path and an extract destination filesystem path. This object locates a dynamic native library inside the stock jar filesystem based on a classpath input stream (i.e., classpath file locator routine).

Parameters:

libraryPath - the path of the library inside the jar filesystem

destination - the extraction destination filesystem path
