public ChangeSetPerformer(final ChangeSet<E> changeSet)

Constructs a ChangeSetPerformer with the changes from this ChangeSet

Parameters

changeSet:ChangeSet<E>: the ChangeSet which operations are used for performing

Method Detail

copyStream	back to summary
private void copyStream(final InputStream inputStream, final O outputStream, final E archiveEntry) throws IOException Copies the ArchiveEntry to the Output stream Parameters inputStream:InputStream the stream to read the data from outputStream:O the stream to write the data to archiveEntry:E the entry to write Exceptions IOException: if data cannot be read or written

copyStream

back to summary

private void copyStream(final InputStream inputStream, final O outputStream, final E archiveEntry) throws IOException

Copies the ArchiveEntry to the Output stream

Parameters

inputStream:InputStream: the stream to read the data from
outputStream:O: the stream to write the data to
archiveEntry:E: the entry to write

Exceptions

IOException:: if data cannot be read or written

isDeletedLater	back to summary
private boolean isDeletedLater(final Set<Change<E>> workingSet, final E entry) Checks if an ArchiveEntry is deleted later in the ChangeSet. This is necessary if a file is added with this ChangeSet, but later became deleted in the same set. Parameters entry:E the entry to check Returns:boolean true, if this entry has a deletion change later, false otherwise

isDeletedLater

back to summary

private boolean isDeletedLater(final Set<Change<E>> workingSet, final E entry)

Checks if an ArchiveEntry is deleted later in the ChangeSet. This is necessary if a file is added with this ChangeSet, but later became deleted in the same set.

Parameters

entry:E: the entry to check

Returns:boolean

true, if this entry has a deletion change later, false otherwise

perform	back to summary

private Interface ChangeSetPerformer.ArchiveEntryIterator<E extends org.apache.commons.compress.archivers.ArchiveEntry>

Known Direct Implementers: org.apache.commons.compress.changes.ChangeSetPerformer.ArchiveInputStreamIterator, org.apache.commons.compress.changes.ChangeSetPerformer.ZipFileIterator

Abstracts getting entries and streams for archive entries.

Iterator#hasNext is not allowed to throw exceptions that's why we can't use Iterator<ArchiveEntry> directly - otherwise we'd need to convert exceptions thrown in ArchiveInputStream#getNextEntry.
