.matches?(exists, value, condition) ⇒ true | false, Boolean

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Returns whether a value satisfies a $type expression.

Parameters:

  • exists (true | false) —

    Whether the value exists.

  • value (Object) —

    The value to check.

  • condition (Integer | Array<Integer>) —

    The $type condition predicate which corresponds to the BSON type enumeration.

Returns:

.one_matches?(exists, value, condition) ⇒ true | false, Boolean

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Returns whether a value satisfies a single $type expression value.

Parameters:

  • exists (true | false) —

    Whether the value exists.

  • value (Object) —

    The value to check.

  • condition (Integer) —

    The $type condition predicate which corresponds to the BSON type enumeration.

Returns:

  • (true | false) —

    Whether the value matches.

  • (Boolean)
