Class Overview
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.

Public Constructors
public Oid (String strOid)
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 |
|---|
public Oid (InputStream derOid)
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. |
|---|
public Oid (byte[] data)
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. |
|---|
Public Methods
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
public boolean equals (Object other)
Tests if two Oid objects represent the same Object identifier value.
Parameters
| other | the Oid object that has to be compared to this one |
|---|
Returns
trueif the two Oid objects represent the same value,falseotherwise.
public byte[] 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 |
|---|
public int hashCode ()
Returns a hashcode value for this Oid.
Returns
- a hashCode value
public String toString ()
Returns a string representation of the oid's integer components in dot separated notation.
Returns
- string representation in the following format: "1.2.3.4.5"
