Increment Score¶

Description¶

This operation increments the score of an item by the specified number.

Method¶

Backendless.Hive( hiveName ).SortedSetStore( keyName ).incrementScore( value, scoreValue ): Promise<number>;

where:

Argument	Description
`hiveName`	Name of a hive where the operation is performed. String value.
`keyName`	Key name identifying a sorted-set. String value.
`value`	The value identifying a score-value pair. The score of the corresponding value in the sorted set will be incremented by the number in the `scoreValue` parameter. The value can be of any valid data type.
`scoreValue`	A number that the existing score will be incremented by.

Return Value¶

The incremented score of the item.

Example¶

The example below increments the score associated with the value 'John' by 3.

await Backendless.Hive('leaderboard').SortedSetStore('players').incrementScore('John', 3)

where:

Argument	Description
`'leaderboard'`	Name of a hive in the system.
`'players'`	Name of a sorted set where to increment the score of an item.

Codeless Reference¶

sorted_set_api_increment_score

where:

Argument	Description
`hive name`	Name of a hive where the operation is performed.
`key name`	Key name identifying a sorted set.
`value`	An exact value as one already in the sorted set. The value identifies a score/value pair. The score of the corresponding value in the sorted set will be incremented by the number in the `increment by` parameter.
`increment by`	Specify the number to increment the score of the value.

The operation returns the modified incremented score of the item.

Consider the following Sorted Set storage:
sorted_set_api_example_all_blocks

The example below increments the score of a value "John" by 3:
sorted_set_api_example_increment_score
The output will look as shown below after the Codeless logic runs.

Note how the incremented score forced the score/value pair to change its current position(rank). Before the operation the rank of the "John" value was 1, and after the operation the rank became 2.

Rank in a sorted set determines the position of an element. For more information about the rank, refer to the Hive Overview section of this guide.
