Length

Description

This operation returns the number of items in the sorted set.

Method

Objective-CSwift

[[[Backendless.shared hive:(NSString *)hiveName] sortedSetStore:(NSString *)keyName] lengthWithResponseHandler:^(NSInteger)responseHandler errorHandler:^(Fault *)errorHandler];

Backendless.shared.hive(hiveName: String).sortedSetStore(keyName: String).length(responseHandler: ((Int) -> Void)!, errorHandler: ((Fault) -> Void)!)

where:

Argument	Description
hiveName	Name of a hive where the operation is performed. String value.
keyName	Key name identifying a sorted-set. String value.

Return Value

The total number of elements stored in the sorted set.

Example

The example below returns the number of items in the sorted set:

Objective-CSwift

[[[Backendless.shared hive:@"leaderboard"] sortedSetStore:@"players"] lengthWithResponseHandler:^(NSInteger response) {
    // handle response
} errorHandler:^(Fault *fault) {
    // handle error
}];

Backendless.shared.hive("leaderboard").sortedSetStore("players").length(responseHandler: { response in
    // handle response
}, errorHandler: { fault in
    // handle error
})

where:

Argument	Description
"leaderboard"	Name of a hive where the operation is performed.
"players"	Key name identifying a sorted set.

Codeless Reference

where:

Argument	Description
hive name	Name of a hive where the operation is performed.
key name	Key name identifying a sorted set.

Returns the total number of elements stored in the requested sorted set.

Consider the following Sorted Set storage:

The example below returns the number of items stored in the "players".

The output will look as shown below after the Codeless logic runs.
