Class Oid
- java.lang.Object
org.ietf.jgss.Oid
- public class Oid
- extends java.lang.Object
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.

Constructor Detail
Oid
- public Oid(java.lang.String strOid)
- throws GSSException
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
- public Oid(java.io.InputStream derOid)
- throws GSSException
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. Oid
- public Oid(byte[] data)
- throws GSSException
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 InputStream conterpart.
Parameters:
data
- byte array containing the DER encoded oid Throws:
GSSException
- may be thrown when the DER encoding does not
follow the prescribed format. Method Detail
toString
- public java.lang.String toString( )
Returns a string representation of the oid's integer components
in dot separated notation.
Overrides:
toString
in class java.lang.Object
Returns:
string representation in the following format: "1.2.3.4.5"
equals
- public boolean equals(java.lang.Object other)
Tests if two Oid objects represent the same Object identifier
value.
Overrides:
equals
in class java.lang.Object
Parameters:
other
- the Oid object that has to be compared to this one Returns:
true
if the two Oid objects represent the same
value, false
otherwise. getDER
- public byte[] getDER()
- throws GSSException
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
- public boolean containedIn(Oid[] oids)
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
hashCode
- public int hashCode()
Returns a hashcode value for this Oid.
Overrides:
hashCode
in class java.lang.Object
Returns:
a hashCode value
