Function Details

noop_read_filter/1

noop_read_filter(X :: term()) -> term()

noop_write_filter/3

noop_write_filter(Old :: term(), WF :: term(), Val :: term()) ->
                     {term(), none}

init/1

init(DBName :: atom() | tuple()) -> state()

close/1

close(State :: state()) -> true

Closes the given DB (it may be recoverable using open/1 depending on the DB back-end).

close_and_delete/1

close_and_delete(State :: state()) -> true

Closes the given DB and deletes all contents (this DB can thus not be re-opened using open/1).

set_entry/2

set_entry(NewEntry :: entry(), TableName :: state()) -> state()

delete_entry/2

delete_entry(TableName :: state(), Entry :: entry()) ->
                db_prbr:db()

get_load/1

get_load(State :: state()) -> non_neg_integer()

tab2list/1

tab2list(State :: state()) -> [{any(), any()}]

tab2list_raw_unittest/1
