Method Detail

serialize

public int serialize(int offset,
            byte[] data)

Create a byte array consisting of an SST record and any required Continue records, ready to be written out.

If an SST record and any subsequent Continue records are read in to create this instance, this method should produce a byte array that is identical to the byte array produced by concatenating the input records' data.

Returns:

the byte array

getUnicodeString

private UnicodeString getUnicodeString(int index)

getUnicodeString

private static UnicodeString getUnicodeString(IntMapper strings,
                             int index)

getBucketAbsoluteOffsets

public int[] getBucketAbsoluteOffsets()

getBucketRelativeOffsets

public int[] getBucketRelativeOffsets()
