Return a new array of bytes. The bytearray class is a mutable sequence of integers in the range 0 <= x < 256. It has most of the usual methods of mutable sequences, described in Mutable Sequence Types, as well as most methods that the bytes type has, see Bytes and Bytearray Operati...
Intead of storing the whole array as a snapshot, using TreeMaps to store every snapshots of every element in the array. Following are some useful methods of TreeMap: publicMap.Entry<K,V> floorEntry(Kkey) Returns:an entry with the greatest key less than or equal tokey, ornullif there ...
As noted above, the micro mirror device according to the present invention may be driven by formation of a piezoelectric material diaphragm at one side of the micro mirror, or by thermal deformation of structures, in addition to the driving methods employing the electromagnetic force or electrostati...
