Interface TwosComplement

All Known Subinterfaces:

TwosComplement.Signed, TwosComplement.Unsigned

All Known Implementing Classes:

Adapter.AsByte, Adapter.AsByte.Signed, Adapter.AsByte.Unsigned, Adapter.AsInt, Adapter.AsInt.Signed, Adapter.AsInt.Unsigned, Adapter.AsLong, Adapter.AsLong.Signed, Adapter.AsLong.Unsigned, Adapter.AsShort, Adapter.AsShort.Signed, Adapter.AsShort.Unsigned

public interface TwosComplement

Methods that have variants on twos-complement Java types that might be signed or unsigned.

The Signed or Unsigned subinterface below, as appropriate, can be used as a mixin on a class where the right treatment of a Java long, int, short, or byte might be class-specific.

The semantic difference between a short treated as unsigned and a char (also an unsigned 16-bit type) is whether the value is expected to mean what UTF-16 says it means.
