  Class and Description
  IdentityIndexer Defines an abstract trivial indexer that identically projects the contents of some stateful node, and can therefore save space.
  NullIndexer Defines an abstract trivial indexer that projects the contents of some stateful node to the empty tuple, and can therefore save space.
  ProjectionIndexer An iterable indexer that receives updates from a node, and groups received tuples intact, i.e.

  Class and Description
  AggregatorNode A special node depending on a projection indexer to aggregate tuple groups with the same projection.
  DualInputNode Abstract superclass for nodes with two inputs that are matched against each other.
  DualInputNode.Side
  GenericProjectionIndexer A generic Indexer capable of indexing along any valid TupleMask.
  IdentityIndexer Defines an abstract trivial indexer that identically projects the contents of some stateful node, and can therefore save space.
  Indexer A node that indexes incoming Tuples by their signatures as specified by a TupleMask.
  IndexerListener A listener for update events concerning an Indexer.
  IndexerWithMemory
  IterableIndexer An indexer that allows the iteration of all retrievable tuple groups (or reduced groups).
  NullIndexer Defines an abstract trivial indexer that projects the contents of some stateful node to the empty tuple, and can therefore save space.
  ProjectionIndexer An iterable indexer that receives updates from a node, and groups received tuples intact, i.e.
  SpecializedProjectionIndexer A specialized projection indexer that can be memory-less (relying on an external source of information).
  StandardIndexer An abstract standard implementation of the Indexer interface, providing common bookkeeping functionality.
