Constructor Detail

ConcurrentJarCreator

public ConcurrentJarCreator(int nThreads)
                     throws IOException

Creates a new ConcurrentJarCreator instance.

ConcurrentJarCreator creates zip files using several concurrent threads.

This constructor has the same effect as ConcurrentJarCreator(true, nThreads)

Parameters:

nThreads - The number of concurrent thread used to create the archive

Throws:

IOException

ConcurrentJarCreator

public ConcurrentJarCreator(boolean compressAddedZips,
                            int nThreads)
                     throws IOException

Creates a new ConcurrentJarCreator instance.

ConcurrentJarCreator creates zip files using several concurrent threads. Entries that are already zip file could be just stored or compressed again.

Parameters:

compressAddedZips - Indicates if entries that are zip files should be compressed. If set to false entries that are zip files will be added using ZipEntry.STORED method. If set to true entries that are zip files will be added using the compression method indicated by the ZipArchiveEntry passed to addArchiveEntry(ZipArchiveEntry, InputStreamSupplier, boolean). The compression method for all entries that are not zip files will not be changed regardless of the value of this parameter

nThreads - The number of concurrent thread used to create the archive

Throws:

IOException

Method Detail

createDeferred

public static org.apache.commons.compress.archivers.zip.ScatterZipOutputStream createDeferred(org.apache.commons.compress.parallel.ScatterGatherBackingStoreSupplier scatterGatherBackingStoreSupplier)
                                                                                       throws IOException

Throws:

IOException

addArchiveEntry

public void addArchiveEntry(org.apache.commons.compress.archivers.zip.ZipArchiveEntry zipArchiveEntry,
                            org.apache.commons.compress.parallel.InputStreamSupplier source,
                            boolean addInParallel)
                     throws IOException

Adds an archive entry to this archive.

This method is expected to be called from a single client thread

Parameters:

zipArchiveEntry - The entry to add. Compression method

source - The source input stream supplier

addInParallel - Indicates if the entry should be add in parallel. If set to false the entry is added synchronously.

Throws:

IOException

writeTo

public void writeTo(org.apache.commons.compress.archivers.zip.ZipArchiveOutputStream targetStream)
             throws IOException,
                    ExecutionException,
                    InterruptedException

Throws:

IOException

ExecutionException

InterruptedException

getStatisticsMessage

public String getStatisticsMessage()

Returns a message describing the overall statistics of the compression run

Returns:

A string
