Increment¶

Description¶

This operation increments the value of the specified key by a specific number.

Method¶

Backendless.Hive(hiveName).MapStore(keyName).increment(objKey, value);

where:

Argument	Description
`hiveName`	Name of a hive where the operation is performed. String value.
`keyName`	Key name identifying a map. String value.
`objKey`	Key name identifying a key-value pair. String value.
`value`	Specify the number to increment the value of the specified key.

Return Value¶

The incremented value.

Examples¶

Increment The Value By n + 1

The example below increments the value of the key "Apples" by 1. When this operation is used without the value parameter, then the value is always incremented by 1 for every request made.

Backendless.Hive("groceryStore").MapStore("fruits").increment("Apples", 1);

where:

Argument	Description
`"groceryStore"`	Name of a hive where the operation is performed.
`"fruits"`	Key name identifying a map.

Increment The Value By A Number

The example below increments the value of the key "Apples" by 5.

Backendless.Hive("groceryStore").MapStore("fruits").increment("Apples", 5);

where:

Argument	Description
`"groceryStore"`	Name of a hive where the operation is performed.
`"fruits"`	Key name identifying a map.

Codeless Reference¶

map_api_increment

where:

Argument	Description
`hive name`	Name of a hive where the operation is performed.
`key name`	Key name identifying a map.
`object key name`	Key name identifying a key-value pair.
`increment by`	Specify the number to increment the value of the specified key.

Returns the incremented value.

Consider the following Map storage:
map_apI_example_map_store_6

The example below increments the value of the key "Apples" by 5.

map_api_example_increment

The map will look as shown below after the Codeless logic runs:
map_apI_example_map_store_7
