Constructors

  • Do not use this constructor!

    Meant for internal use only.

    Parameters

    • message: string = 'Tailable cursor does not support this operation'

    Returns MongoTailableCursorError

    This class is only meant to be constructed within the driver. This constructor is not subject to semantic versioning compatibility guarantees and may change at any time.

Properties

cause?: Error
code?: string | number

This is a number in MongoServerError and a string in MongoDriverError

connectionGeneration?: number
message: string
stack?: string
topologyVersion?: TopologyVersion
stackTraceLimit: number

The Error.stackTraceLimit property specifies the number of stack frames collected by a stack trace (whether generated by new Error().stack or Error.captureStackTrace(obj)).

The default value is 10 but may be set to any valid JavaScript number. Changes will affect any stack trace captured after the value has been changed.

If set to a non-number value, or set to a negative number, stack traces will not capture any frames.

Accessors

  • get errmsg(): string
  • Legacy name for server error responses

    Returns string

  • get errorLabels(): string[]
  • Returns string[]

  • get name(): string
  • Returns string

Methods

  • Checks the error to see if it has an error label

    Parameters

    • label: string

      The error label to check for

    Returns boolean

    returns true if the error has the provided error label

  • Creates a .stack property on targetObject, which when accessed returns a string representing the location in the code at which Error.captureStackTrace() was called.

    const myObject = {};
    Error.captureStackTrace(myObject);
    myObject.stack; // Similar to `new Error().stack`

    The first line of the trace will be prefixed with ${myObject.name}: ${myObject.message}.

    The optional constructorOpt argument accepts a function. If given, all frames above constructorOpt, including constructorOpt, will be omitted from the generated stack trace.

    The constructorOpt argument is useful for hiding implementation details of error generation from the user. For instance:

    function a() {
    b();
    }

    function b() {
    c();
    }

    function c() {
    // Create an error without stack trace to avoid calculating the stack trace twice.
    const { stackTraceLimit } = Error;
    Error.stackTraceLimit = 0;
    const error = new Error();
    Error.stackTraceLimit = stackTraceLimit;

    // Capture the stack trace above function b
    Error.captureStackTrace(error, b); // Neither function c, nor b is included in the stack trace
    throw error;
    }

    a();

    Parameters

    • targetObject: object
    • OptionalconstructorOpt: Function

    Returns void
