BaseAssemblyNode Represents a node in a tree responsible for assembling outer join query results.
BranchOptionalAssemblyNode Assembly node for an event stream that is a branch with a single optional child node below it.
BranchRequiredAssemblyNode Assembly node for an event stream that is a branch with a single required child node below it.
CartesianProdAssemblyNode Assembly node for an event stream that is a branch with a two or more child nodes (required and optional) below it.
CartesianProdAssemblyNode.ChildStreamResults Structure to represent a list of event result rows per stream.
CartesianUtil Helper class to compute the cartesian product of the events from two streams.
LeafAssemblyNode Assembly node for an event stream that is a leaf with a no child nodes below it.
