Method Detail

indexInfoSerializer

public IndexInfo.Serializer indexInfoSerializer()

Specified by:

indexInfoSerializer in interface RowIndexEntry.IndexSerializer<IndexInfo>

serialize

public void serialize(RowIndexEntry<IndexInfo> rie,
                      DataOutputPlus out,
                      java.nio.ByteBuffer indexInfo)
               throws java.io.IOException

Specified by:

serialize in interface RowIndexEntry.IndexSerializer<IndexInfo>

Throws:

java.io.IOException

serializeForCache

public void serializeForCache(RowIndexEntry<IndexInfo> rie,
                              DataOutputPlus out)
                       throws java.io.IOException

Specified by:

serializeForCache in interface RowIndexEntry.IndexSerializer<IndexInfo>

Throws:

java.io.IOException

deserializeForCache

public RowIndexEntry<IndexInfo> deserializeForCache(DataInputPlus in)
                                             throws java.io.IOException

Specified by:

deserializeForCache in interface RowIndexEntry.IndexSerializer<IndexInfo>

Throws:

java.io.IOException

skipForCache

public static void skipForCache(DataInputPlus in)
                         throws java.io.IOException

Throws:

java.io.IOException

deserialize

public RowIndexEntry<IndexInfo> deserialize(DataInputPlus in,
                                            long indexFilePosition)
                                     throws java.io.IOException

Specified by:

deserialize in interface RowIndexEntry.IndexSerializer<IndexInfo>

Throws:

java.io.IOException

deserializePositionAndSkip

public long deserializePositionAndSkip(DataInputPlus in)
                                throws java.io.IOException

Specified by:

deserializePositionAndSkip in interface RowIndexEntry.IndexSerializer<IndexInfo>

Throws:

java.io.IOException

readPosition

public static long readPosition(DataInputPlus in)
                         throws java.io.IOException

Reads only the data 'position' of the index entry and returns it. Note that this left 'in' in the middle of reading an entry, so this is only useful if you know what you are doing and in most case 'deserialize' should be used instead.

Throws:

java.io.IOException

skip

public static void skip(DataInputPlus in,
                        Version version)
                 throws java.io.IOException

Throws:

java.io.IOException

serializeOffsets

public static void serializeOffsets(DataOutputBuffer out,
                                    int[] indexOffsets,
                                    int columnIndexCount)
                             throws java.io.IOException

Throws:

java.io.IOException
