Method Detail

select

String select(int index)

multi

String multi()

Marks the start of a transaction block. Subsequent commands will be queued for atomic execution using EXEC.

Returns:

always OK

discard

String discard()

Flushes all previously queued commands in a transaction and restores the connection state to normal.

If WATCH was used, DISCARD unwatches all keys.

Returns:

always OK

watch

String watch(String... keys)

O(1) for every keys.

Marks the given keys to be watched for conditional execution of a transaction.

Parameters:

keys - keys to be watched

Returns:

always OK.

Since:

2.1.0

unwatch

String unwatch()

O(1).

Flushes all the previously watched keys for a transaction.

If you call EXEC or DISCARD, there's no need to manually call UNWATCH.

Returns:

always OK.

Since:

2.1.0

exec

List<Object> exec()

Executes all previously queued commands in a transaction and restores the connection state to normal.

When using WATCH, EXEC will execute commands only if the watched keys were not modified, allowing for a check-and-set mechanism.

Returns:

each element being the reply to each of the commands in the atomic transaction.

When using WATCH, EXEC can return a Null multi-bulk reply if the execution was aborted.
