AssemblyBase

Base class template for assembly operations.

template <
  class LinearAlgebraType,
  class Operand>
class AssemblyBase;

Template parameters
LinearAlgebraType	Target linear algebra type (e.g., sparse matrix, vector)
Operand	Variational form type (e.g., BilinearForm, LinearForm)

Provides the interface for assembling variational forms into discrete linear algebra objects (matrices and vectors). Different specializations handle bilinear forms, linear forms, boundary conditions, and problems.
