Constructor Detail

UuidType

public UuidType(UUID item)

Creates a new uuid type.

Parameters:

item - to DER encode

UuidType

public UuidType(DERTag tag,
                UUID item)

Creates a new uuid type.

Parameters:

tag - der tag associated with this type

item - to DER encode

Throws:

IllegalArgumentException - if the der tag is constructed

Method Detail

encode

public byte[] encode()

Description copied from interface: DEREncoder

Encode this object into its DER type.

Specified by:

encode in interface DEREncoder

Returns:

DER encoded object

decode

public static UUID decode(DERBuffer encoded)

Converts bytes in the buffer to a uuid by reading from the current position to the limit.

Parameters:

encoded - buffer containing DER-encoded data where the buffer is positioned at the start of uuid bytes and the limit is set beyond the last byte of uuid data.

Returns:

decoded bytes as a uuid.

readLong

protected static long readLong(DERBuffer buffer)

Reads the next 8 bytes from the supplied buffer to create a long.

Parameters:

buffer - to read

Returns:

UUID component integer

toBytes

public static byte[] toBytes(UUID uuid)

Converts the supplied uuid to a byte array.

Parameters:

uuid - to convert

Returns:

byte array
