Method Detail

get

public static ArchiveFormat get()

Required by ArchiveFormatFactory.

getName

public java.lang.String getName()

Specified by:

getName in interface ArchiveFormat

Returns:

A short, familiar text which describes this archive format, e.g. '7z', 'zip', 'tar'

isArchiveFileName

public boolean isArchiveFileName(java.lang.String fileName)

Specified by:

isArchiveFileName in interface ArchiveFormat

Returns:

Whether the given fileName is typical for this ArchiveFormat

getArchiveFileName

public java.lang.String getArchiveFileName(java.lang.String fileName)

Description copied from interface: ArchiveFormat

Maps the given fileName to the name that a corresponding archive file would have. This is typically achieved by appending a suffix, like '.7z', '.zip', '.tar'.

Specified by:

getArchiveFileName in interface ArchiveFormat

archiveInputStream

public org.apache.commons.compress.archivers.ArchiveInputStream archiveInputStream(java.io.InputStream is)

Specified by:

archiveInputStream in interface ArchiveFormat

Returns:

An ArchiveInputStream for this format which reads from the given input stream

open

public org.apache.commons.compress.archivers.ArchiveInputStream open(java.io.File archiveFile)
                                                              throws java.io.IOException

Description copied from interface: ArchiveFormat

Opens an existing archive file for reading.

Specified by:

open in interface ArchiveFormat

Returns:

An ArchiveInputStream for this format which reads from the given archiveFile

Throws:

java.io.IOException

archiveOutputStream

public org.apache.commons.compress.archivers.ArchiveOutputStream archiveOutputStream(java.io.OutputStream os)

Specified by:

archiveOutputStream in interface ArchiveFormat

Returns:

An ArchiveOutputStream for this format which writes to the given output stream

create

public org.apache.commons.compress.archivers.ArchiveOutputStream create(java.io.File archiveFile)
                                                                 throws java.io.IOException

Description copied from interface: ArchiveFormat

Creates a new archive file.

Specified by:

create in interface ArchiveFormat

Returns:

An ArchiveOutputStream for this format which writes to the given archiveFile

Throws:

java.io.IOException

writeEntry

public void writeEntry(org.apache.commons.compress.archivers.ArchiveOutputStream archiveOutputStream,
                       java.lang.String name,
                       ConsumerWhichThrows<java.io.OutputStream,java.io.IOException> writeContents)
                throws java.io.IOException

Description copied from interface: ArchiveFormat

Appends an entry with the given contents to the given archiveOutputStream. The archive entry is filled with "standard values", except for the entry 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

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

Throws:

java.io.IOException

writeEntry

public void writeEntry(org.apache.commons.compress.archivers.ArchiveOutputStream archiveOutputStream,
                       org.apache.commons.compress.archivers.ArchiveEntry archiveEntry,
                       @Nullable
                       java.lang.String name,
                       ConsumerWhichThrows<java.io.OutputStream,java.io.IOException> writeContents)
                throws java.io.IOException

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

Throws:

java.io.IOException

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
