Examples of redis.clients.jedis.Jedis.incr()

redis.clients.jedis.Jedis.incr()

Increment the number stored at key by one. If the key does not exist or contains a value of a wrong type, set the key to the value of "0" before to perform the increment operation.

INCR commands are limited to 64 bit signed integers.

Note: this is actually a string operation, that is, in Redis there are not "integer" types. Simply the string stored at the key is parsed as a base 10 64 bit signed integer, incremented, and then converted back as a string.

Time complexity: O(1) @see #incrBy(String,long) @see #decr(String) @see #decrBy(String,long) @param key @return Integer reply, this commands will reply with the new value of keyafter the increment.
