接口 RawComparable

所有已知实现类:

ByteArray

public interface RawComparable

Interface for objects that can be compared through RawComparator. This is useful in places where we need a single object reference to specify a range of bytes in a byte array, such as Comparable or Collections.binarySearch(java.util.List, Object, Comparator) The actual comparison among RawComparable's requires an external RawComparator and it is applications' responsibility to ensure two RawComparable are supposed to be semantically comparable with the same RawComparator.
