### Basics and Library organization
|
||||
|

This library consists of several building blocks. For simple usage, the most important building blocks are [ranges](#ranges), [indices](#indices) and [array types](#arrays).

#### Ranges

#### Ranges {#sec-ranges}
|
||||
|

Basically, a *range* defines a meta data space. There are several range class types, which are derived from the abstract base class `RangeBase`. Ranges can only be created by the corresponding factory and exclusively exist within a shared pointer; they cannot be copied. Available range class types are:

* `YRange` : The same as `MRange` but the number of ranges and their types can be specified at runtime.

#### Indices
|

#### Indices {#sec-indices}
|
||||
|
||||
For each range type there is a corresponding index type (`CIndex`, `UIndex<MetaT>`, `SIndex<MetaT,S>`, `PIndex<IndexT>`, `MIndex<IndexTs...>`, `YIndex`). They act as const iterators on the ranges and are a crucial component to define operations on containers. In contrast to the ranges, all index types must be known at compile time (static polymorphism, `IndexInterface<Index,MetaT>`).

* `BIndex<T>` : The same as `AIndex`, but not const.

#### Array types
|

#### Array types {#sec-array-types}
|
||||
|
||||
Finally, there are the container classes (arrays), which are derived from `CArrayBase<T>` (const) or `ArrayBase<T>` for a given data type `T`. All arrays are defined on a range, their data can be accessed or iterated over using suitable indices. The array-type actually containing data is called `MArray<T>`. Moreover, there exist array-types that do not contain data, but view the data of other arrays or at least parts of the data. These are called `CSlice<T>` (const view) or `Slice`.
