## Instance Method Details

### #<<(stat) ⇒ Object

Increments a stat by one.

 31 32 33 # File 'lib/resque/stat.rb', line 31 def <<(stat) incr stat end

### #>>(stat) ⇒ Object

Decrements a stat by one.

 44 45 46 # File 'lib/resque/stat.rb', line 44 def >>(stat) decr stat end

### #[](stat) ⇒ Object

Alias of `get`

 18 19 20 # File 'lib/resque/stat.rb', line 18 def [](stat) get(stat) end

### #clear(stat) ⇒ Object

Removes a stat from Redis, effectively setting it to 0.

 49 50 51 # File 'lib/resque/stat.rb', line 49 def clear(stat) redis.del("stat:#{stat}") end

### #decr(stat, by = 1) ⇒ Object

For a string stat name, decrements the stat by one.

Can optionally accept a second int parameter. The stat is then decremented by that amount.

 39 40 41 # File 'lib/resque/stat.rb', line 39 def decr(stat, by = 1) redis.decrby("stat:#{stat}", by) end

### #get(stat) ⇒ Object

 13 14 15 # File 'lib/resque/stat.rb', line 13 def get(stat) redis.get("stat:#{stat}").to_i end

### #incr(stat, by = 1) ⇒ Object

For a string stat name, increments the stat by one.

Can optionally accept a second int parameter. The stat is then incremented by that amount.

 26 27 28 # File 'lib/resque/stat.rb', line 26 def incr(stat, by = 1) redis.incrby("stat:#{stat}", by) end
