Class	Description
AbstractFilteringStage<T>	Base class for Stage implementations that iterate over each Item in a collection and do something, then optionally remove the item being processed.
AbstractItemMetadataSelectionStage<T,B>	An abstract Stage that selects Items for further processing if they have a specific type of ItemMetadata attached to them.
AbstractIteratingStage<T>	Base class for Stage implementations that iterate over each Item in a collection and do something.
AbstractStage<T>	A base class for Stage implementations.
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.
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.
ItemIdTransformStage<T>	A pipeline stage that, taking 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.
ItemOrderingStage<T>	A Stage capable of ordering a collection of Items according to a supplied strategy.
ItemOrderingStrategy<T>	A strategy that defines how to order a Item collection.
MDQueryMD5ItemIdTransformer	Transforms a string into another string that is the MD5 hash of the UTF-8 encoding of the original string, prepended with "{md5}".
MDQuerySHA1ItemIdTransformer	Transforms a string into another string that is the hex-encoded representation of the SHA1 hash of the UTF-8 encoding of the original string, prepended with "{sha1}".
MultiOutputSerializationStage<T>	A stage which writes the given item collection out to multiple destinations.
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.
PipelineAndStrategy<T>	Representation of a Pipeline and the Predicate to be used as a strategy to select items sent to that pipeline.
PipelineDemultiplexerStage<T>	A stage which, given an item collection and a list of PipelineAndStrategy objects each representing a Pipelines and associated selection strategy Predicate, 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 List that can then be used as the input source for another pipeline.
PipelineProcessingException	Base exception for errors that occur within the pipeline execution.
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 according to a provided selection strategy and passes selected items to one pipeline and non-selected items to another.
Stage<T>	A stage in a Pipeline that operates upon a collection Item in a particular manner.
StageProcessingException	Exception indicating that a Stage of the pipeline encountered an error.
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.
TerminationException	An exception to be thrown to cause command-line aggregator execution to terminate.
