Method Detail

of

public static InstantCoder of()

encode

public void encode(Instant value,
          java.io.OutputStream outStream,
          Coder.Context context)
            throws CoderException,
                   java.io.IOException

Description copied from interface: Coder

Encodes the given value of type T onto the given output stream in the given context.

Throws:

CoderException - if the value could not be encoded for some reason

java.io.IOException - if writing to the OutputStream fails for some reason

decode

public Instant decode(java.io.InputStream inStream,
             Coder.Context context)
               throws CoderException,
                      java.io.IOException

Description copied from interface: Coder

Decodes a value of type T from the given input stream in the given context. Returns the decoded value.

Throws:

CoderException - if the value could not be decoded for some reason

java.io.IOException - if reading from the InputStream fails for some reason

isDeterministic

@Deprecated
public boolean isDeterministic()

Deprecated.

Description copied from interface: Coder

Returns true if the coding is deterministic.

In order for a Coder to be considered deterministic, the following must be true:

• two values which compare as equal (via Object.equals() or Comparable.compareTo(), if supported), have the same encoding.
• the 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.

verifyDeterministic

public void verifyDeterministic()

Description copied from interface: Coder

Throw Coder.NonDeterministicException if the coding is not deterministic.

In order for a Coder to be considered deterministic, the following must be true:

• two values which compare as equal (via Object.equals() or Comparable.compareTo(), if supported), have the same encoding.
• the 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.
