Method Detail

alreadyContains

public boolean alreadyContains(String path)

close

public abstract void close()
                    throws IOException

No more output will be sent to this OutputFileSet. It is safe to call close() on an already-closed instance.

Throws:

IOException

getPathDescription

public String getPathDescription()

Return a description of this output file set's path. The precise meaning is unspecified, except that it should be informative when used in log messages.

openForWrite

public final OutputStream openForWrite(String path)
                                throws IOException

Opens a file for write. If writing to a zip file and the file already exists, this has no effect. Otherwise, overwrites any existing file.

Returns:

the output stream to write to, possibly a NullOutputStream

Throws:

IOException

openForWrite

public OutputStream openForWrite(String path,
                                 long timeStampMillis)
                          throws IOException

Opens a file for write. If writing to a zip file and the file already exists, there will be no effect. If writing to a directory, the file exists, and the given timestamp is older or equal to the file's current timestamp, there will be no effect.

Parameters:

timeStampMillis - last modified time in milliseconds, or TIMESTAMP_UNAVAILABLE to force an overwrite.

Returns:

the output stream to write to, possibly a NullOutputStream

Throws:

IOException

createNewOutputStream

protected abstract OutputStream createNewOutputStream(String path,
                                                      long lastModifiedTime)
                                               throws IOException

Throws:

IOException
