Gets a value indicating whether this instance has immutable result.

Gets the immutable result.

The data values to compute the result value for the current request from. These values are provided from the inputs of the virtual column identified by the external id, and more generally the properties, of this request. The values are ordered in the same order as the inputs were given in the input collection. If one of the inputs have been deleted an invalid value will occur in its place.

Returns true if the work item has been canceled.

Returns true if the work item result is valid in the live document. This will be false if the worker model changed after the work item was added to the dispatcher.

Gets the associated worker model generation. This can be used by the worker to cache information based on the worker model state. Should be avoided whenever possible. Caching should instead be handled via the caching behavior, the model key and item key functions of the worker factory.

Gets the properties of the container that the result value is produced for.

Gets or sets a tag object. The tag object can be used to associate information with the work item.
