Method Detail

queryOnPartition

Collection<QueryableEntry> queryOnPartition(String mapName,
                                          Predicate predicate,
                                          int partitionId)

Query a specific partition.

Parameters:

mapName - map name.

predicate - any predicate.

partitionId - partition id.

Returns:

result of query

queryLocalMember
