Detailed Description
template<int D, class T>
class Array< D, T >
multi dimensional arrays
Multidimensional arrays were conceived for a number of reasons. In various software we needed some way to handle large volumes of data while providing different views on the data. Currently, giving the considerations of a read-only memory this library would probably be redefined completely. Nevertheless at that time, my main interest was the multidimensional operations that were possible and a way to store retrieve them in a platform transparent manner. Some of the uses:
BpmDj
- In BpmDj this kind of arrays is used to access audio on disk. There we need to load left/right samples one by one an put them into an output stream. As such we need a physical addressing of stream length x 2 short integers.
- The Fourier transformation that we realize on some of the data chunks works on a channel per channel bases. There we need an internal representation of 2 x stream length data (doubles) then.
Gel Analysis
- In the gel analysis soft we need images that have a number of channels and then the standard x en y coordinates. Often the 3 colors are accessed at the same time.
- In the gel analysis soft we also need a array handler that transforms the input coordinate system into an orthonormal basis in which -1:1 always will capture the entire image.
Petri-nets
- In the Petri-Net usage we have tokens that are placed in queues. To this end a general purpose array can be used. However, since theoretically tokens must be of a specified type we might as well give a limitation on what kind of content can be stored into an array.
The problem of cross platform access to data has not yet vanished, as such most of these data expression are still useful to read data from files and save it if we write our own flow modules.

| Size< D > | sizes | |||
| ) | [inline] |
This constructor accepts a SpecialStorage type (see array-storage). It will increase the reference counter immediately with one, effectively taking ownership of the data since it will also delete the data when the counter reaches zero.
