Examples of umontreal.iro.lecuyer.util.BitVector

umontreal.iro.lecuyer.util.BitVector
This class implements vectors of bits and the operations needed to use them. The vectors can be of arbitrary length. The operations provided are all the binary operations available to the int and long primitive types in Java.
All bit operations are present in two forms: a normal form and a self form. The normal form returns a newly created object containing the result, while the self form puts the result in the calling object (this). The return value of the self form is the calling object itself. This is done to allow easier manipulation of the results, making it possible to chain operations.
