containerdescriptors.hh
A class augmenting std::tuple by element access via operator[].
Definition: tuplevector.hh:35
Utility to generate an array with a certain value.
decltype(auto) constexpr unpackIntegerSequence(F &&f, std::integer_sequence< I, i... > sequence)
Unpack an std::integer_sequence<I,i...> to std::integral_constant<I,i>...
Definition: indices.hh:124
std::integral_constant< std::size_t, i > index_constant
An index constant with value i.
Definition: indices.hh:29
typename impl::_Child< Node, indices... >::type Child
Template alias for the type of a child node given by a list of child indices.
Definition: childextraction.hh:225
ImplementationDefined child(Node &&node, Indices... indices)
Extracts the child of a node given by a sequence of compile-time and run-time indices.
Definition: childextraction.hh:128
STL namespace.
Descriptor for arrays with all children identical and the number of children a static size.
Definition: containerdescriptors.hh:129
static constexpr std::size_t size()
The static size information, i.e., number of children.
Definition: containerdescriptors.hh:147
UniformArray()
Default constructor. Is enable if the child-type is default constructible.
Definition: containerdescriptors.hh:133
UniformArray(Child child)
Constructor that stores a single child only.
Definition: containerdescriptors.hh:138
const Child & operator[](const Index &) const
Access the i'th child that is always the same, i.e., child_.
Definition: containerdescriptors.hh:144
Uniform descriptor with dynamic size.
Definition: containerdescriptors.hh:168
UniformVector(std::size_t size, Child child)
Constructor that stores the size and a single child only.
Definition: containerdescriptors.hh:178
std::size_t size() const
The dynamic size information, i.e., number of children.
Definition: containerdescriptors.hh:188
UniformVector(std::size_t size)
Default constructor with size. Is enable if the child-type is default constructible.
Definition: containerdescriptors.hh:172
const Child & operator[](const Index &) const
Access the i'th child that is always the same, i.e., child_.
Definition: containerdescriptors.hh:185
Fallback container descriptor if nothing else fits.
Definition: containerdescriptors.hh:50
The node in the descriptor tree representing a value placeholder.
Definition: containerdescriptors.hh:83
static constexpr std::size_t size()
A value placeholder does not have any sub-descriptors, thus its size is zero.
Definition: containerdescriptors.hh:89
Value operator[](const Index &) const
The child access method is only available for the interface, but should not be called.
Definition: containerdescriptors.hh:86
Provides the TupleVector class that augments std::tuple by operator[].
Utilities for type computations, constraining overloads, ...
