UUIDBasedOID
Construct a new OID with a Type 3 UUID (that is based on an MD5 hash of the supplied byte arrayss).
Given the same bytes as input, the same OID will be returned every time.
The name space represents the entity, an instance of which is being uniquely identified.
The name bytes might, for example, be a UTF-8 encoding of a String that contains a bunch of attribute values separated by some delimiter like a "|"
- Parameters:
nameSpace
- a non-null UUID defining the name spacebName
- a non-null non-zero length array of bytes containing the "name" (any values)
-
UUIDBasedOID
public UUIDBasedOID()Construct a new OID with a new random UUID.
-
UUIDBasedOID
Construct an OID from an existing string representation of an OID.
- Parameters:
oid
- a String of dotted numeric values in OID form {joint-iso-itu-t uuid(25) <uuid-single-integer-value>}- Throws:
IllegalArgumentException
NumberFormatException

Method Details
-
getByteArrayInNetworkByteOrderFromUUID
-
getOID
Get the string representation of the OID.
- Returns:
- the string representation of the OID
-
getUUID
Get the UUID of the OID.
- Returns:
- the UUID
-
parseUUIDFromOID
public static UUID parseUUIDFromOID(String oid) throws IllegalArgumentException, NumberFormatException Extract the UUID from a UUID-based OID.
- Parameters:
oid
- a String of dotted numeric values in OID form {joint-iso-itu-t uuid(25) <uuid-single-integer-value>}- Returns:
- the UUID
- Throws:
IllegalArgumentException
- if the OID is not in the {joint-iso-itu-t uuid(25)} arcNumberFormatException
- if the OID does not contain a uuid-single-integer-value
-
parseUUIDFromDecimalString
Extract the UUID from its single integer value decimal string representation.
- Parameters:
decimalString
- single integer value decimal string representation- Returns:
- the UUID
- Throws:
NumberFormatException
- if the OID does not contain a uuid-single-integer-value
-
makeBigIntegerFromUnsignedLong
Convert an unsigned value in a long to a BigInteger.
- Parameters:
unsignedLongValue
- an unsigned long value (i.e., the sign bit is treated as part of the value rather than a sign)- Returns:
- the BigInteger
-
createOIDFromUUIDCanonicalHexString
public static String createOIDFromUUIDCanonicalHexString(String hexString) throws IllegalArgumentException Create an OID from the canonical hex string form of a UUID.
- Parameters:
hexString
- canonical hex string form of a UUID- Returns:
- the OID
- Throws:
IllegalArgumentException
- if name does not conform to the string representation
-
main
Convert OIDs to UUIDs and UUIDs to OIDs or create a new one.
- Parameters:
args
- a list of OIDs or UUIDs or empty if a new OID is to be created
