T - the type of the elements of the setpublic class SetCoder<T> extends IterableLikeCoder<T,java.util.Set<T>>
SetCoder encodes any Set using the format of IterableLikeCoder. The
elements may not be in a deterministic order, depending on the Set implementation.Coder.Context, Coder.NonDeterministicException| Modifier | Constructor and Description |

throws Coder.NonDeterministicException
Coder.NonDeterministicException if the coding is not deterministic.
In order for a Coder to be considered deterministic, the following must be true:
Object.equals() or Comparable.compareTo(), if supported) have the same encoding.
Coder always produces a canonical encoding, which is the same for an instance
of an object even if produced on different computers at different times.

order of an arbitrary iteration.Coder.NonDeterministicException - if this coder is not deterministic.public TypeDescriptor<java.util.Set<T>> getEncodedTypeDescriptor()
