struct IndexBasisSpec¶
what IndexBasisRegistry::add(label, space, instance, spec) registers a named basis instance with besides its label, space and instance: each member is given by name, and each is optional; as for IndexSpaceSpec, a bare value in the brace list is rejected
Public Members
- SEQUANT_DESIGNATED_INIT_ONLY
-
std::optional<std::int64_t> extent = {}¶
the number of functions in the basis; if not given, the dimension of its space, now and whenever that changes (see IndexBasis::own_extent())
- Pre:
non-negative
-
std::optional<IndexBasisMetric> metric = {}¶
whether the basis is orthonormal; IndexBasisMetric::Unit if not given
-
std::optional<Field> field = {}¶
the scalar field of the basis; if not given, that of its space’s own basis, now and whenever that changes (see IndexBasis::own_field())
-
std::optional<Label> follows = {}¶
the label of the named basis instance to follow (see IndexBasisRegistry::follow()), whose extent, metric and field the basis then mirrors; excludes the three members above
