setRegionKey

public Region.Builder<K> setRegionKey(RegionKey key)

setKeyProvider

public Region.Builder<K> setKeyProvider(IKeyProvider<K> keyProvider)

setSectorSize

public Region.Builder<K> setSectorSize(int sectorSize)

addHeaderEntry

public Region.Builder<K> addHeaderEntry(IHeaderDataEntryProvider<?,K> headerEntry)

addSpecialSectorMapEntry

public Region.Builder<K> addSpecialSectorMapEntry(java.lang.Object marker,
                                                  int value,
                                                  java.util.function.Function<K,java.nio.ByteBuffer> specialReader,
                                                  java.util.function.BiConsumer<K,java.nio.ByteBuffer> writeConflictHandler)

Creates a special IntPackedSectorMap entry type, with custom read function. The supplied conflict handler should handle conflicts in such way that the supplied reader will return the previously written value, or throw an exception is this is not possible.

Parameters:

marker - a marker object used to specify writing special value

value - the raw int header value

specialReader - data reader for this special value

writeConflictHandler - function for handling conflicts when writing real data with the same sectormap value.
