Method Detail

get

public static ArchiveFormat get()

Required by ArchiveFormatFactory.

getName

public java.lang.String getName()

Specified by:

getName in interface ArchiveFormat

Returns:

writeEntry

public void writeEntry(org.apache.commons.compress.archivers.ArchiveOutputStream archiveOutputStream,
                       java.lang.String name,

writeContents is called exactly once unless the name designates a directory entry

Specified by:

writeEntry in interface ArchiveFormat

Parameters:

archiveOutputStream - Must match this ArchiveFormat

name - The name for the entry; may be slightly changed (in particulary wrt/ leading and trailing slashes) before the entry is created

writeContents - Writes the entry's contents to the 'subject' output stream

See Also:

ArchiveFormat.writeDirectoryEntry(ArchiveOutputStream, String)

writeDirectoryEntry

public void writeDirectoryEntry(org.apache.commons.compress.archivers.ArchiveOutputStream archiveOutputStream,
                                java.lang.String name)

Description copied from interface: ArchiveFormat

Appends a 'directory entry', i.e. an entry without contents, to the given archiveOutputStream. The archive entry is filled with "standard values", except for the entry name.

Specified by:

writeDirectoryEntry in interface ArchiveFormat

Parameters:

archiveOutputStream - Must match this ArchiveFormat

name - The name for the entry; may be slightly changed (in particulary wrt/ leading and trailing slashes) before the entry is created

writeEntry

public void writeEntry(org.apache.commons.compress.archivers.ArchiveOutputStream archiveOutputStream,
                       org.apache.commons.compress.archivers.ArchiveEntry archiveEntry,

                       java.lang.String name,
                       ConsumerWhichThrows<? super java.io.OutputStream,? extends java.io.IOException> writeContents)

Description copied from interface: ArchiveFormat

Appends the given archiveEntry with the given contents to the given archiveOutputStream. If name is not null, then it overrides the name in the archive entry.

If the type of the archiveEntry does not match this ArchiveFormat, then it is automatically converted to the correct type, preserving as much information as possible ('re-archiving').

writeContents is called exactly once unless the archiveEntry is a directory entry.

Specified by:

writeEntry in interface ArchiveFormat

Parameters:

archiveOutputStream - Must match this ArchiveFormat

archiveEntry - May or may not match this ArchiveFormat (see above)

name - Overrides the name in the archiveEntry, or null

writeContents - Writes the entry's contents to the 'subject' output stream

matches

public boolean matches(byte[] signature,
                       int signatureLength)

Specified by:

matches in interface ArchiveFormat

Returns:

Whether the first few bytes of archive data match what is expected for this format

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
