Class UUID

The UUID implements an immutable universally unique identifier. It is used to identifier different types of objects uniquely, from SceneObject to Resource.

Note

As all TypeScript types, the UUID is an identity, not a value type. To compare two UUIDs, use the UUID.isEqual method and do not compare by identity (X == Y).

empty: UUID

A zero initialized UUID.

Accessors

data0

  • get data0(): number

  • The data part of the UUID.

    Returns number

data1

  • get data1(): number

  • The data part of the UUID.

    Returns number

data2

  • get data2(): number

  • The data part of the UUID.

    Returns number

data3

    Returns number

Methods

clone

  • clone(): UUID

  • Clones this instance and returns a new UUID with identical values.

    Returns UUID

isEmpty

  • isEmpty(): boolean

  • Checks has the UUID been initialized to a valid value.

    Returns boolean

    True if UUID is initialized.

isEqual

  • isEqual(rhs): boolean

  • Determines if both UUIDs are equal.

    Parameters

    Returns boolean

toBigInt

  • toBigInt(): bigint

    Returns string

StaticfromBigInt

  • fromBigInt(value): UUID

  • Creates a new UUID from the specified BigInt value.

    Parameters

    • value: bigint

      The UUID in BigInt representation.

StaticfromString

  • fromString(uuid): UUID

  • Creates a new UUID from the specified uuid string.

    Parameters

    • uuid: string

      The UUID string
