cacheHexString: boolean

Accessors

_bsontype

• get _bsontype(): ObjectId

• Overrides BSONValue._bsontype

  Returns ObjectId

id

• get id(): Uint8Array

• The ObjectId bytes

  ---

  Returns Uint8Array

Methods

equals

• equals(otherId: string | ObjectId | ObjectIdLike): boolean

• Compares the equality of this ObjectId with otherID.

  ---

  Parameters

  • otherId: string | ObjectId | ObjectIdLike

    ObjectId instance to compare against.

  Returns boolean

getTimestamp

• getTimestamp(): Date

• Returns the generation date (accurate up to the second) that this ID was generated.

  ---

  Returns Date

inspect

• inspect(): string

• Overrides BSONValue.inspect

  Returns string

toHexString

• toHexString(): string

• Returns the ObjectId id as a 24 character hex string representation

  ---

  Returns string

toJSON

• toJSON(): string

• Converts to its JSON the 24 character hex string representation.

  ---

  Returns string

toString

• toString(encoding?: hex | base64): string

• Converts the id into a 24 character hex string for printing, unless encoding is provided.

  ---

  Parameters

  • optionalencoding: hex | base64

    hex or base64

  Returns string

staticcreateFromBase64

• createFromBase64(base64: string): ObjectId

• Creates an ObjectId instance from a base64 string

  ---

  Parameters

  • base64: string

  Returns ObjectId

staticcreateFromHexString

• createFromHexString(hexString: string): ObjectId

• Creates an ObjectId from a hex string representation of an ObjectId.

  ---

  Parameters

  • hexString: string

    create a ObjectId from a passed in 24 character hexstring.

  Returns ObjectId

staticcreateFromTime

• createFromTime(time: number): ObjectId

• Creates an ObjectId from a second based number, with the rest of the ObjectId zeroed out. Used for comparisons or sorting the ObjectId.

  ---

  Parameters

  • time: number

    an integer number representing a number of seconds.

  Returns ObjectId

staticgenerate

• generate(time?: number): Uint8Array

• Generate a 12 byte id buffer used in ObjectId's

  ---

  Parameters

  • optionaltime: number

    pass in a second based timestamp.

  Returns Uint8Array

staticisValid

• isValid(id: string | number | Uint8Array | ObjectId | ObjectIdLike): boolean

• Checks if a value is a valid bson ObjectId

  ---

  Parameters

  • id: string | number | Uint8Array | ObjectId | ObjectIdLike

    ObjectId instance to validate.

  Returns boolean
