All RFC 4122 UUID instances in ramsey/uuid implement a ``getFields()`` method
|
|
that returns an instance of ``Rfc4122\FieldsInterface``.
|
|
|
|
.. php:namespace:: Ramsey\Uuid\Rfc4122
|
|
|
|
.. php:interface:: FieldsInterface

|
Represents the fields of an RFC 4122 UUID.
|
|
|
|
.. php:method:: getBytes()
|
|

:returns: (*string*) The bytes that comprise these fields.
|
|
|
|
.. php:method:: getClockSeq()
|
|
|
|
:returns: (*Ramsey\\Uuid\\Type\\Hexadecimal*) The full 16-bit clock sequence, with the variant bits (two most significant bits) masked out.
|
|
|
|
.. php:method:: getClockSeqHiAndReserved()
|
|
|
|
:returns: (*Ramsey\\Uuid\\Type\\Hexadecimal*) The high field of the clock sequence multiplexed with the variant.
|
|
|
|
.. php:method:: getClockSeqLow()
|
|
|
|
:returns: (*Ramsey\\Uuid\\Type\\Hexadecimal*) The low field of the clock sequence.
|
|
|
|
.. php:method:: getNode()
|
|
|
|
:returns: (*Ramsey\\Uuid\\Type\\Hexadecimal*) The node field.
|
|
|
|
.. php:method:: getTimeHiAndVersion()
|
|
|
|
:returns: (*Ramsey\\Uuid\\Type\\Hexadecimal*) The high field of the timestamp multiplexed with the version.
|
|
|
|
.. php:method:: getTimeLow()
|
|
|
|
:returns: (*Ramsey\\Uuid\\Type\\Hexadecimal*) The low field of the timestamp.
|
|
|
|
.. php:method:: getTimeMid()
|
|
|
|
:returns: (*Ramsey\\Uuid\\Type\\Hexadecimal*) The middle field of the timestamp.
|
|
|
|
.. php:method:: getTimestamp()
|
|
|
|
:returns: (*Ramsey\\Uuid\\Type\\Hexadecimal*) The full 60-bit timestamp, without the version.
|
|
|
|
.. php:method:: getVariant()
|
|
|

Returns the variant, which, for RFC 4122 variant UUIDs, should always be
|
|
the value ``2``.
|
|
|
|
:returns: (*int*) The UUID variant.
|
|
|
|
.. php:method:: getVersion()
|
|
|
|
:returns: (*int*) The UUID version.
|
|
|
|
.. php:method:: isNil()
|
|
|
|
A *nil* UUID is a special type of UUID with all 128 bits set to zero.
|
|
Its string standard representation is always
|
|
``00000000-0000-0000-0000-000000000000``.
|
|
|
|
:returns: (*bool*) True if this UUID represents a nil UUID.
