Method Detail

extract

public void extract(int[] indices,
                    boolean testMode,
                    IArchiveExtractCallback extractCallback)
             throws SevenZipException

Extract archive items with indices indices.
Note: passing sorted indices array is more efficient. But it isn't suggested to manually sort indices with something like Arrays.sort(int[]). Sort indices only, if you can do it quicker, that generic sort algorithms: O(n*log(n)).

Specified by:

extract in interface IInArchive

Parameters:

indices - (optional) array of indices of archive items to extract.
null - all archive items.

testMode - true - test archive items only
false - extract archive items

extractCallback - extraction callback object. Optional implementation of ICryptoGetTextPassword.

Throws:

SevenZipException - 7-Zip or 7-Zip-JBinding error occur. Use SevenZipException.printStackTraceExtended() to get stack traces of this SevenZipException and of the all thrown 'cause by' exceptions.
