Method Detail

createTimeoutException

public static RedisCommandTimeoutException createTimeoutException(Duration timeout)

Create a RedisCommandTimeoutException with a detail message given the timeout.

Parameters:

timeout - the timeout value.

Returns:

the RedisCommandTimeoutException.

createTimeoutException

public static RedisCommandTimeoutException createTimeoutException(String message,
                                                                  Duration timeout)

Create a RedisCommandTimeoutException with a detail message given the message and timeout.

Parameters:

message - the detail message.

timeout - the timeout value.

Returns:

the RedisCommandTimeoutException.

formatTimeout

public static String formatTimeout(Duration duration)

createExecutionException

public static RedisCommandExecutionException createExecutionException(String message)

Create a RedisCommandExecutionException with a detail message. Specific Redis error messages may create subtypes of RedisCommandExecutionException.

Parameters:

message - the detail message.

Returns:

the RedisCommandExecutionException.

createExecutionException

public static RedisCommandExecutionException createExecutionException(String message,
                                                                      Throwable cause)

Create a RedisCommandExecutionException with a detail message and optionally a cause. Specific Redis error messages may create subtypes of RedisCommandExecutionException.

Parameters:

message - the detail message.

cause - the nested exception, may be null.

Returns:

the RedisCommandExecutionException.

isUnknownCommandError

public static boolean isUnknownCommandError(Throwable error)

Check whether an error reply indicates that the server does not know the command or subcommand that was sent.

Matches the shapes Redis and Redis-compatible servers use for this condition, which differ in wording and word order: ERR unknown command 'CLIENT', with args beginning with: ..., ERR Unknown subcommand or wrong number of arguments for 'MYID' and the Redis Enterprise discovery service's ERR sentinel unknown command. The words are therefore not required to be adjacent, and unknown is matched case-insensitively. The ERR prefix is not, since Redis error codes are uppercase by convention.

Parameters:

error - the error to inspect, may be null.

Returns:

true if error is a Redis error reply reporting an unknown command or subcommand.
