ObjectId

@ExperimentalTime

class ObjectId : Comparable<ObjectId> (source)

A 12-bytes identifier for MongoDB objects.

This class allows accessing all fields of an ObjectId as well as constructing instances from existing data. However, it doesn't provide a way to generate new randomized ObjectId instances (as that depends on the database configuration). To do so, see opensavvy.ktmongo.bson.BsonContext.newId.

Constructors

constructor(timestamp: Instant, processId: Long, counter: Int)

Constructs a new ObjectId from its different components.

constructor(bytes: ByteArray)

Constructs a new ObjectId by reading a byte array.

constructor(hex: String)

Constructs a new ObjectId by reading a hexadecimal representation.

Types
