writeAll

default void writeAll(Iterable<QueryableMaintenanceStore.Row> rows)
               throws QueryableMaintenanceStore.SerializationException

Throws:

QueryableMaintenanceStore.SerializationException

writeAll

void writeAll(Stream<QueryableMaintenanceStore.Row> rows)
       throws QueryableMaintenanceStore.SerializationException

Throws:

QueryableMaintenanceStore.SerializationException

writeRaw

default void writeRaw(Iterable<QueryableMaintenanceStore.RawRow> rows)

void writeRaw(Stream<QueryableMaintenanceStore.RawRow> rows)

clear

void clear()

Deletes all entries from the store. If the store has been created limited to a concrete parent or a subset of parents, only the entries for this parent(s) will be deleted.

iterateAll

QueryableMaintenanceStore.MaintenanceIterator<T> iterateAll()

Returns an iterator to iterate over all entries in the store. If the store has been created limited to a concrete parent or a subset of parents, only the entries for this parent(s) will be returned. The iterated values offer additional methods to update or delete entries.
The iterator must be closed after usage. Otherwise, updates may not be persisted.

close

void close()
