This class is used to encapsulate a pointer into an array, for use with Microsoft® J/Direct™ methods. When used as a parameter to a J/Direct method, an object of type ArrayWithOffset will be marshaled to a pointer to the given byte offset in the given array. No bounds checks are performed on the offset given in the constructor. Objects of type ArrayWithOffset are immutable—once created, they cannot be modifed.
