Method Detail

encode

public UUID encode(UUID uuid)

Get a .Ned Guid from a random-based UUID (v4).

It rearranges the most significant bytes from big-endian to little-endian, and vice-versa.

The .Net Guid stores the most significant bytes as little-endian, while the least significant bytes are stored as big-endian (network order).

Specified by:

encode in interface UuidCodec<UUID>

Parameters:

uuid - a UUID

Returns:

another UUID

Throws:

InvalidUuidException - if the argument is invalid

decode

public UUID decode(UUID uuid)

Get a random-based UUID (v4) from a .Net Guid.

It rearranges the most significant bytes from big-endian to little-endian, and vice-versa.

The .Net Guid stores the most significant bytes as little-endian, while the least significant bytes are stored as big-endian (network order).

Specified by:

decode in interface UuidCodec<UUID>

Parameters:

uuid - a UUID

Returns:

another UUID

Throws:

InvalidUuidException - if the argument is invalid
