Classes in dev.morphia.aggregation.experimental.stages used by dev.morphia.aggregation.experimental

Class	Description
AddFields	Adds new fields to documents.
AutoBucket	Categorizes incoming documents into a specific number of groups, called buckets, based on a specified expression.
Bucket	Categorizes incoming documents into groups, called buckets, based on a specified expression and bucket boundaries.
CollectionStats	Returns statistics regarding a collection or view.
CurrentOp	Returns a stream of documents containing information on active and/or dormant operations as well as inactive sessions that are holding locks as part of a transaction.
Facet	Processes multiple aggregation pipelines within a single stage on the same set of input documents.
GeoNear	Outputs documents in order of nearest to farthest from a specified point.
GraphLookup	Performs a recursive search on a collection, with options for restricting the search by recursion depth and query filter.
Group	Groups input documents by the specified _id expression and for each distinct grouping, outputs a document.
Lookup	Performs a left outer join to an unsharded collection in the same database to filter in documents from the “joined” collection for processing.
Merge	Writes the results of the aggregation pipeline to a specified collection.
Out	Takes the documents returned by the aggregation pipeline and writes them to a specified collection.
Projection	Passes along the documents with the requested fields to the next stage in the pipeline.
Redact	Restricts the contents of the documents based on information stored in the documents themselves.
ReplaceRoot	Replaces the input document with the specified document.
ReplaceWith	Replaces the input document with the specified document.
Sort	Sorts all input documents and returns them to the pipeline in sorted order.
Stage	Base type for stages.
Unset	Removes/excludes fields from documents.
Unwind	Deconstructs an array field from the input documents to output a document for each element.
