Interface Summary
Interface	Description
MultiOutputSerializationStage.Destination	Interface implemented by destination objects created by an `MultiOutputSerializationStage.OutputStrategy`.
MultiOutputSerializationStage.OutputStrategy<T>	Interface to be implemented by strategy object determining where an item should be written.
Pipeline<T>	A pipeline represents an ordered list of `Stage` that operate on a collection of `Item`.
Stage<T>	A stage in a `Pipeline` that operates upon a collection `Item` in a particular manner.

Class Summary
Class	Description
AbstractItemMetadataSelectionStage<T>	A `Stage` that selects Items for further processing if they have a specific type of `ItemMetadata` attached to them.
AtLeastCollectionPredicate<T>	A `Predicate` which returns `true` if and only if the number of elements in the supplied collection is at least the configured minimum value.
BaseIteratingStage<T>	Base class for `Stage` implementations that iterate over each `Item` in a collection and do something.
BaseStage<T>	A base class for `Stage` implementations.
ComponentInfo	Some basic information related to a component's processing of an `Item`.
CompositeStage<T>	A stage that is composed of other stages.
FilesInDirectoryMultiOutputStrategy<T>	An output strategy for use with the `MultiOutputSerializationStage` which generates individual files within a directory.
FutureSupport	Helper class for dealing with `Future` values.
FutureSupport.FutureNow<T>	An implementation of `Future` that returns a value that is already known.
ItemIdTransformStage<T>	A pipeline stage that, takes each `ItemId` associated with an `Item`, transforms its value using a set of registered transformers, and associates an additional `ItemId` (whose value is the result of the transform) with the element.
ItemMetadataAddingStage<T>	A pipeline stage that adds a collection of `ItemMetadata` objects to each `Item`'s item metadata.
ItemMetadataFilterStage<T>	A `Stage` that filters out `Item` if they have a specific type of `ItemMetadata` attached to them.
ItemMetadataTerminationStage<T>	A `Stage` that terminates pipeline processing if an `Item` has a specific type of `ItemMetadata` attached to it.
MDQueryMD5ItemIdTransformer	Transforms a string into another string that is the MD5 hash of the original string prepended with "{md5}".
MDQuerySHA1ItemIdTransformer	Transforms a string into another string that is the SHA1 hash of the original string prepended with "{sha1}".
MultiOutputSerializationStage<T>	A stage which writes the given item collection out to multiple destinations.
PipelineCallable<T>	A `Callable` that executes a `Pipeline` and returns the given item collection.
PipelineDemultiplexerStage<T>	A stage which, given an item collection and a list of `Pipeline` and `Predicate` pairs, sends the collection of item copies selected by the predicate to the associated pipeline.
PipelineMergeStage<T>	This `Stage` allows the merging of multiple pipeline outputs into a single `Collection` that can then be used as the input source for another pipeline.
ScriptletStage<T>	A pipeline stage that computes that transforms the collection of `Item` via a script.
SerializationStage<T>	A stage which writes the given item collection out to a file using a provided `ItemCollectionSerializer`.
SimplePipeline<T>	A very simple implementation of `Pipeline`.
SplitMergeStage<T>	A stage which splits a given collection and passes selected items to one pipeline and non-selected items to another.
StaticItemSourceStage<T>	A stage which adds a static collection of Items to a `Item` collection.
StatusMetadataLoggingStage<T>	A `Stage` that logs `StatusMetadata` associated with an `Item`.

Exception Summary
Exception	Description
PipelineProcessingException	Base exception for errors that occur within the pipeline execution.
StageProcessingException	Exception indicating that a `Stage` of the pipeline encountered an error.
TerminationException	An exception to be thrown to cause command-line aggregator execution to terminate.
