public abstract class ComparableBinding
extends java.lang.Object

Bindings are used to represent comparable Java objects as ByteIterable. There are several inheritors of the ComparableBinding class, they allow to serialize a value of any Java primitive type or String to ArrayByteIterable, as well as to deserialize ByteIterable to a value. All the inheritors contain two static methods: one for getting ByteIterable entry from a value, and another for getting value from a ByteIterable entry.

Bindings save natural order of values. This means that the greater the value, the greater the ByteIterable entry. The order of the ByteIterable entries is defined by ByteIterableUtil.compare(ByteIterable, ByteIterable). The only exceptions are DoubleBinding and FloatBinding, they save order only for unsigned non-negative values.
