Increment¶
Description¶
This operation increments the value of the specified key by a specific number.
Method¶
Backendless.Hive(hiveName).MapStore(keyName).increment(key, count): Promise<number>;
where:
Argument | Description |
---|---|
hiveName |
Name of a hive where the operation is performed. String value. |
keyName |
Key name identifying a map. String value. |
key |
Key name identifying a key-value pair. String value. |
count |
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 count
parameter, then the value is always incremented by 1
for every request made.
await Backendless.Hive('groceryStore').MapStore('fruits').increment('Apples')
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
.
await 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¶
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:
The example below increments the value of the key "Apples"
by 5
.
