Interface SequenceFile.Sorter.RawKeyValueIterator

Enclosing class:

SequenceFile.Sorter

public static interface SequenceFile.Sorter.RawKeyValueIterator

The interface to iterate over raw keys/values of SequenceFiles.

Method Summary

Modifier and Type	Method and Description
void	close() closes the iterator so that the underlying streams can be closed
org.apache.hadoop.io.DataOutputBuffer	getKey() Gets the current raw key
org.apache.hadoop.util.Progress	getProgress() Gets the Progress object; this has a float (0.0 - 1.0) indicating the bytes processed by the iterator so far
SequenceFile.ValueBytes	getValue() Gets the current raw value
boolean	next() Sets up the current key and value (for getKey and getValue)

Method Detail

getKey

org.apache.hadoop.io.DataOutputBuffer getKey()
                                      throws IOException

Gets the current raw key

Returns:

DataOutputBuffer

Throws:

IOException

getValue

SequenceFile.ValueBytes getValue()
                          throws IOException

Gets the current raw value

Returns:

ValueBytes

Throws:

next

boolean next()
      throws IOException

Sets up the current key and value (for getKey and getValue)

Returns:

true if there exists a key/value, false otherwise

Throws:

IOException

close

void close()
