This interface defines a strategy for how Tar entries are written to a tar file. Different implementations of this interface create Tar files formatted in different ways.
Implementations of this interface is used by the TarBuilder
.

void writeFile(DataSink out, ReadableFile f, AbsoluteLocation location, TarEntrySettings effectiveSettings, Date lastModified) throws WrappedIOException, ArchiveEntryAddException
out
- The DataSink
to write to. This may be a
RandomAccess
object. When this method is called, the DataSink
is positioned at the start of the entry to write. If this
method returns successfully, the DataSink
should be positioned at
the next block boundary after the written entry (the Tar file is divided
into 512-byte blocks).f
- The file to add to the archive. If this file is in a locking
FileSystem
, it is locked for reading by the caller before this
method is called.location
- The absolute location of the entry in the Tar archive.effectiveSettings
- The effective settings for the entry.lastModified
- The time when the file entity was last modified.
WrappedIOException
- On I/O errors.
ArchiveEntryAddException
- If the file entry cannot be added for
some other reason than an I/O error.void writeFileFromStream(RandomAccess out, InputStream is, AbsoluteLocation location, TarEntrySettings effectiveSettings, Date lastModified) throws WrappedIOException, ArchiveEntryAddException
out
- The RandomAccess
to write to. When this method is
called, the RandomAccess
is positioned at the start of the entry
to write. If this method returns successfully, the RandomAccess
should be positioned at the next block boundary after the written entry
(the Tar file is divided into 512-byte blocks).is
- The stream containing the file's data.location
- The absolute location of the entry in the Tar archive.effectiveSettings
- The effective settings for the entry.lastModified
- The time when the file entity was last modified.
WrappedIOException
- On I/O errors.
ArchiveEntryAddException
