public UUIDBasedOID()
Construct a new OID with a new random UUID.
public UUIDBasedOID(String oid) throws IllegalArgumentException, NumberFormatException
Construct an OID from an existing string representation of an OID.
oid - a String of dotted numeric values in OID form {joint-iso-itu-t uuid(25) <uuid-single-integer-value>}IllegalArgumentExceptionNumberFormatExceptionpublic UUIDBasedOID(UUID nameSpace, byte[] bName)
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 "|"
nameSpace - a non-null UUID defining the name spacebName - a non-null non-zero length array of bytes containing the "name" (any values)public static String createOIDFromUUIDCanonicalHexString(String hexString) throws IllegalArgumentException
Create an OID from the canonical hex string form of a UUID.
hexString - canonical hex string form of a UUIDIllegalArgumentException - if name does not conform to the string representationpublic static byte[] getByteArrayInNetworkByteOrderFromUUID(UUID uuid)
public String getOID()
Get the string representation of the OID.
public UUID getUUID()
Get the UUID of the OID.
public static void main(String[] args)
Convert OIDs to UUIDs and UUIDs to OIDs or create a new one.
args - a list of OIDs or UUIDs or empty if a new OID is to be createdpublic static BigInteger makeBigIntegerFromUnsignedLong(long unsignedLongValue)
Convert an unsigned value in a long to a BigInteger.
unsignedLongValue - an unsigned long value (i.e., the sign bit is treated as part of the value rather than a sign)public static UUID parseUUIDFromDecimalString(String decimalString) throws NumberFormatException
Extract the UUID from its single integer value decimal string representation.
decimalString - single integer value decimal string representationNumberFormatException - if the OID does not contain a uuid-single-integer-valuepublic static UUID parseUUIDFromOID(String oid) throws IllegalArgumentException, NumberFormatException
Extract the UUID from a UUID-based OID.
oid - a String of dotted numeric values in OID form {joint-iso-itu-t uuid(25) <uuid-single-integer-value>}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
