template class holding an array and the current index for write commands. Can be used to easily create an array for low level byte streams
The arraybuilder is intended to be used as a conversion queue for low level byte streams. Arbitrary data can be written into the arraybuider by calling the << operator. During this write operation the data will be convertet into a little endian representation regardles of the source architecture. This can be used when a Little Endian byte stream (i.e. for a serial device) is composed of several data types. Example: To send 1 int and to floats via bytestream in little endian ending: ArrayBuilder ab; ab << int << float1 << float2; send(ab.array); To read out values from the arraybuilder you can simply use the << operator. This will automatically convert the little endian representation to the byte order of the host system.
NOTE: As the arraybuilder converts the data during write and read operations the raw data that is read out from the stream has to be appended without any conversion (use appendWithoutConversion). (TODO: Is there a better Solution to this?)
