    • The getAndRemove method returns the value when key is found otherwise null will be returned. The key will be removed after it is returned.

      Parameters

      • key: string

      Returns Promise<null | TType>

  • increment:function
    • increment(key: string, value: number): Promise<boolean>

    • The increment method increments the given key with given value. Returns true if the key where incremented otherwise false will be returned. If values is not defined then it will increment the key with 1. An error will thrown if the key is not a number.

      Parameters

      • key: string
      • value: number

      Returns Promise<boolean>

      Throws

      TypeError

  • put:function
  • removeAll:function
  • removeByKeyPrefix:function
    • removeByKeyPrefix(prefix: string): Promise<void>

      Parameters

      • prefix: string

      Returns Promise<void>

    • removeMany(keys: string[]): Promise<boolean>

    • The removeMany method removes many keys. Returns true if one of the keys where deleted otherwise false is returned.

      Parameters

      • keys: string[]

      Returns Promise<boolean>

  • update:function
    • update(key: string, value: TType): Promise<boolean>
