Frees up resources.

Override this method to release unmanaged and - optionally - managed resources.

Determines whether the specified obj is the same instance as the current work item.

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Serves as a hash function for a particular type.

Gets the Type of the current instance.

Creates a shallow copy of the current Object.

Adds a result handler to the top of the stack of result handlers. The handler must call ReturnItem when it is finished with the work item.

Allows reading the associated worker model in a thread-safe way.

Signals that a worker or result handler is finished with the work item. The method then passes the work item to the next handler in the stack.

Sets the result value of this request to an empty value.

Sets the result value of this request to an error value, with the provided error message. The error message may not be null or an empty string.

Sets the immutable result.

Sets the result value of this request to an empty value. Unlike SetEmptyResult it will be forgotten by the cache over time enabling new requests. This method is thus intended for temporary errors such as network failures etc.

Sets the result value of this request to a valid value.

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.
