This inheritance list is sorted roughly, but not completely, alphabetically:

[detail level 12]

CADIOS2Writer	Base class for ADIOS2-based writers
CAdjacencyList< T >	This class provides a static adjacency list data structure. It is commonly used to store directed graphs. For each node in the contiguous list of nodes [0, 1, 2, ..., n) it stores the connected nodes. The representation is strictly local, i.e. it is not parallel aware
CBoundingBoxTree< T >	Axis-Aligned bounding box binary tree. It is used to find entities in a collection (often a mesh::Mesh)
CComm	A duplicate MPI communicator and manage lifetime of the communicator
CConstant< T >	Constant value which can be attached to a Form
CCoordinateElement< T >	A CoordinateElement manages coordinate mappings for isoparametric cells
CDirichletBC< T, U >	Object for setting (strong) Dirichlet boundary conditions
CDofMap	Degree-of-freedom map
CElementDofLayout	The class represents the degree-of-freedom (dofs) for an element. Dofs are associated with a mesh entity. This class also handles sub-space dofs, which are views into the parent dofs
CExpression< T, U >	Represents a mathematical expression evaluated at a pre-defined set of points on the reference cell
▼Cfalse_type
Cdependent_false< T >
CFiniteElement< T >
CFiniteElement< T >	Finite Element, containing the dof layout on a reference element, and various methods for evaluating and transforming the basis
CForm< T, U >	A representation of finite element variational forms
CFunction< T, U >	This class represents a function \( u_h \) in a finite element function space \( V_h \), given by
CFunctionSpace< T >	This class represents a finite element function space defined by a mesh, a finite element, and a local-to-global map of the degrees-of-freedom
CGeometry< T >	Geometry stores the geometry imposed on a mesh
CIndexMap	This class represents the distribution index arrays across processes. An index array is a contiguous collection of N+1 indices [0, 1, . . ., N] that are distributed across M processes. On a given process, the IndexMap stores a portion of the index set using local indices [0, 1, . . . , n], and a map from the local indices to a unique global index
CKrylovSolver	This class implements Krylov methods for linear systems of the form Ax = b. It is a wrapper for the Krylov solvers of PETSc
CMatrixCSR< Scalar, Container, ColContainer, RowPtrContainer >	Distributed sparse matrix
CMesh< T >	A Mesh consists of a set of connected and numbered mesh topological entities, and geometry data
CMeshTags< T >	MeshTags associate values with mesh topology entities
CNewtonSolver	This class defines a Newton solver for nonlinear systems of equations of the form \(F(x) = 0\)
▼COperator	This class is a base class for matrices that can be used in petsc::KrylovSolver
CMatrix	It is a simple wrapper for a PETSc matrix pointer (Mat). Its main purpose is to assist memory management of PETSc Mat objects
CScatterer< Allocator >	A Scatterer supports the MPI scattering and gathering of data that is associated with a common::IndexMap
CSLEPcEigenSolver	This class provides an eigenvalue solver for PETSc matrices. It is a wrapper for the SLEPc eigenvalue solver
CSparsityPattern	Sparsity pattern data structure that can be used to initialize sparse matrices. After assembly, column indices are always sorted in increasing order. Ghost entries are kept after assembly
CTable	This class provides storage and pretty-printing for tables. Example usage:
CTimeLogger	Timer logging
CTimeLogManager	Logger initialisation
CTimer	A timer can be used for timing tasks. The basic usage is
CTopology	Topology stores the topology of a mesh, consisting of mesh entities and connectivity (incidence relations for the mesh entities)
CVector	A simple wrapper for a PETSc vector pointer (Vec). Its main purpose is to assist with memory/lifetime management of PETSc Vec objects
CVector< T, Container >	Distributed vector
CVTKFile	Output of meshes and functions in VTK/ParaView format
CXDMFFile	Read and write mesh::Mesh, fem::Function and other objects in XDMF
