Here are the classes, structs, unions and interfaces with brief descriptions:

[detail level 123]

Ncage	Functions for topological network criteria cage types
CCage	This contains a cage, with the constituent rings
CFoundCage	One cage matching a signature, closed or incomplete
CSignature	Ring-size census of a polyhedral cage: size -> number of faces
Nchill	CHILL and CHILL+ structure classification
CBondClassifier	One rule set for classifying bond correlations \(c_{ij}\)
CLinearClassifier	One-versus-rest ridge classifier on a dense feature matrix
CQlmAtom	This is the local orientational bond order parameter \(q_{lm}\), of length \(2l+1\)
CSteinhardtQl	Per-particle Steinhardt order parameters of a single degree \(l\)
CTemplateHit
CVoronoiWeights	The Voronoi facet neighbours of one particle and their area weights
CYlmAtom	This contains a complex vector of length \(2l+1\)
Nclump	Clustering functions. This namespace contains functions that are used in the for clustering ice-like particles
CDomain
Ngpu
CBatchResult
CDeviceInfo
CFootprint
CPlan
Nira
CMatch
CPointGroup
NmolSys	Bare-bones structs used throughout the architecture
CResult	This contains the bond classifier of enum class type bond_type, and the bond correlation factor
CPoint	This contains per-particle information
CPointCloud	This contains a collection of points; contains information for a particular frame
Nnneigh	Functions for building neighbour lists
CSkinNeighborList	Persistent neighbour list with a LAMMPS skin
Nphase
CIceXXIHit
Nprimitive	Functions for generating primitive rings
CVertex	This is a collection of elements, for each point, required for graph traversal
CGraph	This is a per-frame object, containing all the vertices for the particular frame, along with the vector of rings generated
CRingUpdater	Exact frame-to-frame maintenance of the primitive ring network
Nrdf	Three-dimensional partial RDF g_IJ(r)
CPartialRdf
Nring	Topological network criteria functions
CAffiliationUpdater	Exact incremental affiliation across frames
CCageAffiliation	Per-ring affiliation flags, indexed like the input ring vector
CRingSearchIndex	Inverted index from an atom to the rings that contain it
CSeededAtomLabels	Per-atom cage flags from seeded (hysteresis) affiliation
CStackingPlanes	Six-rings that are ice-I stacking planes
Nseams
Ncfg
CRuntime
Nsite
CDensityZ
CGuestOccupancy	Guests read against enumerated cages
CIceClusterIons	Connected components of ice atoms on the water graph, and the ion count per component: each ion is assigned to the cluster of the nearest ice atom within cutoff
CIonEnvironment
CTable
Ntopo
CLocalKey
CFrameFingerprint
CKeyLibrary	A dictionary from local keys to labels: the keys of reference structures (a polymorph library), so any molecule whose rooted neighbourhood matches a reference gets that reference's name
CLibraryMatch
Ntopoparam
CLayerStack
Ntum
CCageCounts
