Class Oid
java.lang.Object
org.ietf.jgss.Oid
This class represents Universal Object Identifiers (Oids) and their
associated operations.
Oids are hierarchically globally-interpretable identifiers used within the GSS-API framework to identify mechanisms and name formats.
The structure and encoding of Oids is defined in ISOIEC-8824 and ISOIEC-8825. For example the Oid representation of Kerberos V5 mechanism is "1.2.840.113554.1.2.2"
The GSSName name class contains public static Oid objects representing the standard name types defined in GSS-API.

Oid
Constructs an Oid object from a string representation of its integer components.- Parameters:
strOid
- the dot separated string representation of the oid. For instance, "1.2.840.113554.1.2.2".- Throws:
GSSException
- may be thrown when the string is incorrectly formatted
-
Oid
Creates an Oid object from its ASN.1 DER encoding. This refers to the full encoding including tag and length. The structure and encoding of Oids is defined in ISOIEC-8824 and ISOIEC-8825. This method is identical in functionality to its byte array counterpart.- Parameters:
derOid
- stream containing the DER encoded oid- Throws:
GSSException
- may be thrown when the DER encoding does not follow the prescribed format.

getDER
Returns the full ASN.1 DER encoding for this oid object, which includes the tag and length.- Returns:
- byte array containing the DER encoding of this oid object.
- Throws:
GSSException
- may be thrown when the oid can't be encoded
-
containedIn
A utility method to test if this Oid value is contained within the supplied Oid array.- Parameters:
oids
- the array of Oid's to search- Returns:
- true if the array contains this Oid value, false otherwise
