CoderT onto the given output stream. Multiple elements can
be encoded next to each other on the output stream, each coder should encode information to
know how many bytes to read when decoding. A common approach is to prefix the encoding with the
element's encoded length.encode in class Coder<MatchResult.Metadata>java.io.IOException - if writing to the OutputStream fails for some reasonCoderException - if the value could not be encoded for some reasonpublic MatchResult.Metadata decode(java.io.InputStream is) throws java.io.IOException
CoderT from the given input stream in the given context. Returns the
decoded value. Multiple elements can be encoded next to each other on the input stream, each
coder should encode information to know how many bytes to read when decoding. A common approach
is to prefix the encoding with the element's encoded length.decode in class Coder<MatchResult.Metadata>java.io.IOException - if reading from the InputStream fails for some reasonCoderException - if the value could not be decoded for some reasonpublic boolean consistentWithEquals()
Codertrue if this Coder is injective with respect to Object.equals(java.lang.Object).
Whenever the encoded bytes of two values are equal, then the original values are equal
according to Objects.equals(). Note that this is well-defined for null.
This condition is most notably false for arrays. More generally, this condition is false
whenever equals() compares object identity, rather than performing a
semantic/structural comparison.
By default, returns false.
