extractInstant() from Comb-String

[nimo23]

One question:

How can I get the Instant from a comb which comes from a String?

var combString = UuidCreator.getPrefixComb().toString();

There is a UuidUtil.extractInstant(), UlidUtil.extractInstant(), but no CombUtil.extractInstant().

When COMB generators were implemented, the extraction methods were left to be implemented in the future. I wasn't sure if anyone was going to need it.

I just released version 3.5.0. The following methods are now available:

• CombUtil.extractPrefix(): returns the unix millis from Prefix COMBs;
• CombUtil.extractSuffix(): returns the unix millis from Suffix COMBs;
• CombUtil.extractPrefixInstant(): // returns the instant from Prefix COMBs;
• CombUtil.extractSuffixInstant(): // returns the instant from Suffix COMBs.

No extraction method was implemented for Short Prefix COMBs and Short Suffix COMBs.

Now to extract the Instant you can do this:

String combString = UuidCreator.getPrefixComb().toString();

StringCodec codec = new StringCodec(); // initialize the canonical string codec
UUID comb = codec.decode(combString); // decode the comb string
Instant instant = CombUtil.extractPrefixInstant(comb); // extract the instant
