Package org.apache.commons.compress.archivers.zip

Provides stream classes for reading and writing archives using the ZIP format.

Interface Summary

Interface	Description
CharsetAccessor	An interface added to allow access to the character set associated with an NioZipEncoding, without requiring a new method to be added to ZipEncoding.
ExtraFieldParsingBehavior	Controls details of parsing zip extra fields.
UnixStat	Constants from stat.h on Unix systems.
UnparseableExtraFieldBehavior	Handles extra field data that doesn't follow the recommended pattern for extra fields with a two-byte key and a two-byte length.
ZipArchiveEntryPredicate	A predicate to test if a #ZipArchiveEntry matches a criteria.
ZipArchiveEntryRequestSupplier	Supplies ZipArchiveEntryRequest.
ZipEncoding	An interface for encoders that do a pretty encoding of ZIP file names.
ZipExtraField	General format of extra field data.

Class Summary

Class	Description
AbstractUnicodeExtraField	A common base class for Unicode extra information extra fields.
AsiExtraField	Adds Unix file permission and UID/GID fields as well as symbolic link handling.
ExtraFieldUtils	ZipExtraField related methods
ExtraFieldUtils.UnparseableExtraField	"enum" for the possible actions to take if the extra field cannot be parsed.
GeneralPurposeBit	Parser/encoder for the "general purpose bit" field in ZIP's local file and central directory headers.
JarMarker	If this extra field is added as the very first extra field of the archive, Solaris will consider it an executable jar file.
ParallelScatterZipCreator	Creates a zip in parallel by using multiple threadlocal ScatterZipOutputStream instances.
PKWareExtraHeader	Base class for all PKWare strong crypto extra headers.
ResourceAlignmentExtraField	An extra field who's sole purpose is to align and pad the local file header so that the entry's data starts at a certain position.
ScatterStatistics	Provides information about a scatter compression run.
ScatterZipOutputStream	A zip output stream that is optimized for multi-threaded scatter/gather construction of zip files.
ScatterZipOutputStream.ZipEntryWriter
StreamCompressor	Encapsulates a Deflater and crc calculator, handling multiple types of output streams.
UnicodeCommentExtraField	Info-ZIP Unicode Comment Extra Field (0x6375):
UnicodePathExtraField	Info-ZIP Unicode Path Extra Field (0x7075):
UnparseableExtraFieldData	Wrapper for extra field data that doesn't conform to the recommended format of header-tag + size + data.
UnrecognizedExtraField	Simple placeholder for all those extra fields we don't want to deal with.
UnsupportedZipFeatureException.Feature	ZIP Features that may or may not be supported.
X000A_NTFS	NTFS extra field that was thought to store various attributes but in reality only stores timestamps.
X0014_X509Certificates	PKCS#7 Store for X.509 Certificates (0x0014).
X0015_CertificateIdForFile	X.509 Certificate ID and Signature for individual file (0x0015).
X0016_CertificateIdForCentralDirectory	X.509 Certificate ID and Signature for central directory (0x0016).
X0017_StrongEncryptionHeader	Strong Encryption Header (0x0017).
X0019_EncryptionRecipientCertificateList	PKCS#7 Encryption Recipient Certificate List (0x0019).
X5455_ExtendedTimestamp	An extra field that stores additional file and directory timestamp data for zip entries.
X7875_NewUnix	An extra field that stores UNIX UID/GID data (owner & group ownership) for a given zip entry.
Zip64ExtendedInformationExtraField	Holds size and other extended information for entries that use Zip64 features.
ZipArchiveEntry	Extension that adds better handling of extra fields and provides access to the internal and external file attributes.
ZipArchiveEntryRequest	A Thread-safe representation of a ZipArchiveEntry that is used to add entries to parallel archives.
ZipArchiveInputStream	Implements an input stream that can read Zip archives.
ZipArchiveOutputStream	Reimplementation of java.util.zip.ZipOutputStream that does handle the extended functionality of this package, especially internal/external file attributes and extra fields with different layouts for local file data and central directory entries.
ZipArchiveOutputStream.UnicodeExtraFieldPolicy	enum that represents the possible policies for creating Unicode extra fields.
ZipEightByteInteger	Utility class that represents an eight byte integer with conversion rules for the little endian byte order of ZIP files.
ZipEncodingHelper	Static helper functions for robustly encoding file names in zip files.
ZipFile	Replacement for java.util.ZipFile.
ZipLong	Utility class that represents a four byte integer with conversion rules for the little endian byte order of ZIP files.
ZipShort	Utility class that represents a two byte integer with conversion rules for the little endian byte order of ZIP files.
ZipSplitReadOnlySeekableByteChannel	MultiReadOnlySeekableByteChannel that knows what a split ZIP archive should look like.
ZipUtil	Utility class for handling DOS and Java time conversions.

Enum Summary

Enum	Description
PKWareExtraHeader.EncryptionAlgorithm	Encryption algorithm.
PKWareExtraHeader.HashAlgorithm	Hash Algorithm
Zip64Mode	The different modes ZipArchiveOutputStream can operate in.
ZipArchiveEntry.CommentSource	Indicates how the comment of this entry has been determined.
ZipArchiveEntry.ExtraFieldParsingMode	How to try to parse the extra fields.
ZipArchiveEntry.NameSource	Indicates how the name of this entry has been determined.

Exception Summary

Exception	Description
UnsupportedZipFeatureException	Exception thrown when attempting to read or write data for a zip entry that uses ZIP features not supported by this library.
Zip64RequiredException	Exception thrown when attempting to write data that requires Zip64 support to an archive and UseZip64 has been set to Never.
