Class Splitter

java.lang.Object
de.das.encrypter.processors.Splitter
public class Splitter extends Object
An instance of this class can be used to split a byte array into individual, smaller blocks. This is necessary if large data packets (larger than 65500 bytes) are to be sent via UDP.

After creating a new instance, each call to the getNext() method returns a block of size KeyTransfer.BUFFER_SIZE, except for the last block when the total size is not an integer multiple of KeyTransfer.BUFFER_SIZE. Then a smaller byte array is returned with the remainder. When the decomposition is finished, "getNext()" returns null.
