Method Summary

Methods

Modifier and Type	Method and Description
boolean	identifierCheck(Bytes entry, int chronicleId) check that the identifier in the entry is from this node
void	readExternalEntry(ThreadLocalCopies copies, VanillaChronicleMap.SegmentState segmentState, Bytes source) The map implements this method to restore its contents.
int	sizeOfEntry(Bytes entry, int chronicleId) The size of entry in bytes
void	writeExternalEntry(Bytes entry, Bytes destination, int chronicleId, long bootstrapTime) The map implements this method to save its contents.

Method Detail

sizeOfEntry

int sizeOfEntry(@NotNull
              Bytes entry,
              int chronicleId)

The size of entry in bytes

Parameters:

entry - an entry in the map

chronicleId - is the channel id used to identify the canonical map or queue

Returns:

the size of the entry

identifierCheck

boolean identifierCheck(@NotNull
                      Bytes entry,
                      int chronicleId)

check that the identifier in the entry is from this node

Parameters:

entry - an entry in the map

chronicleId - is the channel id used to identify the canonical map or queue

Returns:

the size of the entry

writeExternalEntry

void writeExternalEntry(@NotNull
                      Bytes entry,
                      @NotNull
                      Bytes destination,
                      int chronicleId,
                      long bootstrapTime)

The map implements this method to save its contents.

Parameters:

entry - the byte location of the entry to be stored

destination - a buffer the entry will be written to, the segment may reject this operation and add zeroBytes, if the identifier in the entry did not match the maps local

chronicleId - is the channel id used to identify the canonical map or queue

bootstrapTime -

readExternalEntry

void readExternalEntry(@NotNull
                     ThreadLocalCopies copies,
                     @NotNull
                     VanillaChronicleMap.SegmentState segmentState,
                     @NotNull
                     Bytes source)

The map implements this method to restore its contents. This method must read the values in the same sequence and with the same types as were written by writeExternalEntry(). This method is typically called when we receive a remote replication event, this event could originate from either a remote put(K key, V value) or remove(Object key)

Parameters:

copies -

segmentState -

source - bytes to read an entry from
