`class Transaction`

Context for Redis transaction operations using MULTI/EXEC.

Definitions

`def initialize(pool, *arguments)`

Initialize a new transaction context.

Signature

parameter　pool　Pool: The connection pool to use.
parameter　arguments　Array: Additional arguments for the transaction.

Implementation

def initialize(pool, *arguments)
	super(pool)
end

`def multi`

Begin a transaction block.

Implementation

def multi
	call("MULTI")
end

`def watch(*keys)`

Watch keys for changes during the transaction.

Signature

parameter　keys　Array(String): The keys to watch.

Implementation

def watch(*keys)
	sync.call("WATCH", *keys)
end

`def execute`

Execute all queued commands, provided that no watched keys have been modified. It's important to note that even when a command fails, all the other commands in the queue are processed – Redis will not stop the processing of commands.

Implementation

def execute
	sync.call("EXEC")
end

`def discard`

Discard all queued commands in the transaction.

Implementation

def discard
	sync.call("DISCARD")
end
