Owen O'Malley commented on HADOOP-3315:
---------------------------------------
I would suggest splitting the API into two parts a cooked part and raw part.
{code}
public class TFile {
static public class Writer {
public void append(byte[] keyData, int keyOffset, int keyLength,
byte[] valueData, int valueOffset, int valueLength)
throws IOException;
/**
* Get an output stream to write the key and value to. Only valid until the
next call to append.
* The number of bytes written to the stream must equal keyLength +
valueLength.
*/
public OutputStream append(long keyLength, long valueLength) throws
IOException;
}
public static Writer create(Path p, RawComparator comparator) throws
IOException;
static public class Reader {
/**
* Get an input stream to read the key from. available() will return the
number of bytes left.
* Only valid until the next next call on this stream.
*/
public InputStream nextKeyInputStream() throws IOException;
/**
* Get and input stream to read the value from. available will return the
number of bytes left.
* Only valid until the next next call.
*/
public InputStream nextValueInputStream() throws IOException;
}
public static Reader open(Path p, RawComparator comparator) throws
IOException;
}
