public enum MaterialNumberGeneration extends Enum<MaterialNumberGeneration>
Describes the method used to generate the material number part of a UMID, which form the last 16 bytes of a UMID value. The techniques represented by this enumeration are defined in appendix A of SMPTE 330M. The kind of material number generation can be specified when creating a UMID with the UMID factory methods.
To find the corresponding byte value of the material number generation type, call
getMethodCode(). The static method generationMethodFromCode(byte) converts the
byte value code into a value of this enumeration.
The material number generation method is encoded within a UMID value. Call PackageID.getMaterialNumberGenerator()
to find out the kind of instance number generation in use.

|---|
IEEE1394
Material number generation method specified by the IEEE 1394 network method, including
the current date, time and an 8 byte system identifier.
|
Masked
Masked SMPTE material number generation method based on the SMPTE method,
obscuring the details of data using a MD5 hashing function to hide secure information.
|
NotDefined
Material number generation method is not defined.
|
SMPTE
SMPTE material number generation method that uses the system clock, current date, a
a 2-byte random number and a 6 byte system identifier.
|
UUID_UL
SMPTE material number generation methods that uses a given UUID/UL value to define
the material number.

Converts a numeric code for a material number generation type into a value of this enumeration,
as defined in table 3 of SMPTE 330M.

getMethodCode()
Returns the numeric code for the material number generation type, as defined in table 3
of SMPTE 330M.

static MaterialNumberGeneration |
valueOf(String name)
Returns the enum constant of this type with the specified name.

static MaterialNumberGeneration[] |
values()
Returns an array containing the constants of this enum type, in
the order they are declared.

public static final MaterialNumberGeneration NotDefined
Material number generation method is not defined. In this case, the MAJ API generates a completely random UMID from 128 bits of random data.
public static final MaterialNumberGeneration SMPTE
SMPTE material number generation method that uses the system clock, current date, a a 2-byte random number and a 6 byte system identifier.
Maskedpublic static final MaterialNumberGeneration UUID_UL
SMPTE material number generation methods that uses a given UUID/UL value to define the material number.
public static final MaterialNumberGeneration Masked
Masked SMPTE material number generation method based on the SMPTE method, obscuring the details of data using a MD5 hashing function to hide secure information.
