Specifies options to control the buffering behavior of a partitioner

Create a partitioner that takes items from the source enumerable one at a time and does not use intermediate storage that can be accessed more efficiently by multiple threads. This option provides support for low latency (items will be processed as soon as they are available from the source) and provides partial support for dependencies between items (a thread cannot deadlock waiting for an item that the thread itself is responsible for processing).

Use the default behavior, which is to use buffering to achieve optimal performance.

Defines methods to manipulate thread-safe collections intended for producer/consumer usage. This interface provides a unified representation for producer/consumer collections so that higher level abstractions such as can use the collection as the underlying storage mechanism.

Represents a particular manner of splitting an orderable data source into multiple partitions.

Type of the elements in the collection.

Called from constructors in derived classes to initialize the class with the specified constraints on the index keys.

Indicates whether the elements in each partition are yielded in the order of increasing keys. Indicates whether elements in an earlier partition always come before elements in a later partition. If true, each element in partition 0 has a smaller order key than any element in partition 1, each element in partition 1 has a smaller order key than any element in partition 2, and so on. Indicates whether keys are normalized. If true, all order keys are distinct integers in the range [0 .. numberOfElements-1]. If false, order keys must still be distinct, but only their relative order is considered, not their absolute values.
