customize/factory
ramsey/uuid offers a variety of ways to modify the standard behavior of the
library through dependency injection. Using `FeatureSet`_, `UuidFactory`_, and
:php:meth:`Uuid::setFactory() <Ramsey\\Uuid\\Uuid::setFactory()>`, you are able
to replace just about any `builder`_, `codec`_, `converter`_, `generator`_,
`provider`_, and more.
Ordered-time Codec
The ordered-time codec exists to rearrange the bytes of a version 1,
Gregorian time UUID so that the timestamp portion of the UUID is
monotonically increasing. To learn more, see :ref:`customize.ordered-time-codec`.
Timestamp-first COMB Codec
The timestamp-first COMB codec replaces part of a version 4, random UUID
with a timestamp, so that the UUID becomes monotonically increasing. To
learn more, see :ref:`customize.timestamp-first-comb-codec`.
Using a Custom Calculator
It's possible to replace the default calculator ramsey/uuid uses. If your
requirements require a different solution for making calculations, see
:ref:`customize.calculators`.
Using a Custom Validator
If your requirements require a different level of validation or a different
UUID format, you may replace the default validator. See
:ref:`customize.validators`, to learn more.
Replace the Default Factory
Not only are you able to inject alternate builders, codecs, etc. into the
factory and use the factory to generate UUIDs, you may also replace the
global, static factory used by the static methods on the Uuid class. To find
out how, see :ref:`customize.factory`.
