String

void String(String response)

Parameters:

          Data response)

                               List<Data> response)

Parameters:

response - The operation result as an array of serialized byte-array that might have null entries.

ListEntry

void ListEntry(List<Map.Entry<Data,Data>> response)

Parameters:

Authentication

Object Authentication(byte status,
                      @Nullable
                      Address address,
                      @Nullable
                      String uuid,
                      @Nullable
                      String ownerUuid,
                      byte serializationVersion,
                      @Since(value="1.3")
                      String serverHazelcastVersion,
                      @Since(value="1.3") @Nullable
                      List<Member> clientUnregisteredMembers)

Parameters:

status - Authentication result as 0:AUTHENTICATED, 1:CREDENTIALS_FAILED, 2:SERIALIZATION_VERSION_MISMATCH

address - The address of the member server. This value will be null if status is not 0

uuid - Unique string identifying the connected client uniquely. This string is generated by the owner member server on initial connection. When the client connects to a non-owner member it sets this field on the request. This value will be null if status is not 0

ownerUuid - Unique string identifying the server member uniquely.This value will be null if status is not 0

serializationVersion - server side supported serialization version. This value should be used for setting serialization version if status is 2

serverHazelcastVersion - The hazelcast version of the member

clientUnregisteredMembers - The list of members at which the client has no resources. This may be due to the client no connected to the cluster at all or it may be that the cleanup operation is executed at the member and no resources of the particular client is left at the member. The client can use this information to restore its needed resources at the member, e.g. registers its listeners. The list will be empty if this is response to non-owner connection request.

Returns:

Returns the address, uuid and owner uuid.

Partitions

                @Since(value="1.5")
                int partitionStateVersion)

Parameters:

partitions - mappings from member address to list of partition id 's that member owns

partitionStateVersion - strictly increasing version of the partitions table.

ListDistributedObject

void ListDistributedObject(List<DistributedObjectInfo> response)

Parameters:

response - An list of DistributedObjectInfo (service name and object name).

EntryView

void EntryView(@Nullable
               SimpleEntryView<Data,Data> response)

Parameters:

response - Response as an EntryView Data type.

JobProcessInfo

Object JobProcessInfo(List<JobPartitionState> jobPartitionStates,
                      int processRecords)

Parameters:

jobPartitionStates - The state of the job. See Job Partition State Data Type description for details.

processRecords - Number of processed records.

Returns:

The information about the job if exists

CacheKeyIteratorResult

void CacheKeyIteratorResult(int tableIndex,
                            List<Data> keys)

Parameters:

tableIndex - the last tableIndex processed

keys - list of keys

Exception

void Exception(int errorCode,
               String className,
               @Nullable
               String message,
               StackTraceElement[] stacktrace,
               int causeErrorCode,
               @Nullable
               String causeClassName)

Parameters:

errorCode - error code of this exception

className - java class name of exception

message - details of exception

stacktrace - array of stack trace

causeErrorCode - error code of cause of this exception, if there is no cause -1

causeClassName - java class name of the cause of this exception

ReadResultSet

void ReadResultSet(int readCount,
                   List<Data> items,
                   @Since(value="1.5") @Nullable
                   long[] itemSeqs)

Parameters:

readCount - The number of items read from the ringbuffer. This can be different from the size of the item array if a filter was applied when reading and some items were skipped and are not in the returned array. This can also be seen as the delta with which the user should increase his sequence counter after consuming all of the returned items in the result set to request the next set from the ringbuffer.

items - The array of serialized items.

itemSeqs - sequence IDs of returned ringbuffer items. This array can be null if the cluster version is 3.8 or lower. If the cluster version is 3.9 or higher then the array with sequence IDs will be sent. The array size is equal to the size of the items array and the arrays have a one-to-one mapping: the index of the sequence ID in the sequence array is equal to the index of the item in the item array. These sequences can be used to provide the user information to request a subset of the returned set if the user has for some reason stopped processing working when processing this returned set. If the ringbuffer is read without a filter then these sequences are a contiguous range and the size of the arrays is equal to the readCount.

EntriesWithCursor

void EntriesWithCursor(int tableIndex,
                       List<Map.Entry<Data,Data>> entries)

Parameters:

tableIndex - the last tableIndex processed, it is used to act as a cursor to tell where should next batch read begin

entries - list of entries
