-For efficiency reasons all fields of an object or a class (defined as //static//) with the same size in memory should be placed together, which is done by sorting. For this purpose there are three static arrays in //ch.ntb.inf.deep.classItems.Class//. When parsing the fields their size and type is determined and entered according to their size into the appropriate array. Finally, the arrays are read out in proper order and the objects are entered in the lists as shown in the previous figure. +For efficiency reasons all fields of an object or a class (defined as //static//) with the same size in memory should be placed together, which is done by sorting.
