Oid

java.lang.Object
- com.sun.gssapi.Oid

```
public class Oid
extends java.lang.Object
```
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
RFC 2078
This class replaces the following GSS-API functions:
- gss_test_oid_set_member
- gss_release_oid
- gss_oid_to_str
- gss_str_to_oid

public Oid(java.lang.String strOid)
    throws GSSException
```
    Constructs an Oid object from a string representation of its integer components. Will throw a GSSException if the string is improperly formatted.
    
    Parameters:
    
    strOid - the string in either of these two formats: "{1 2 3 3}" or "1.2.3.3".
    
    Throws:
    
    GSSException - may be thrown when the string is incorrectly formatted
  - Oid
```
public Oid(java.io.InputStream derOid)
    throws GSSException
```
    Constructs an Oid object from its DER encoding. The structure and encoding of Oids is defined in ISOIEC-8824 and ISOIEC-8825.
    
    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,
           int offset)
    throws GSSException
```
    Constructs an Oid object from its DER encoding. The structure and encoding of Oids is defined in ISOIEC-8824 and ISOIEC-8825.
    
    Parameters:
    
    data - byte array containing the DER encoded oid
    
    offset - where in the data byte array to start from
    
    Throws:
    
    GSSException - may be thrown when the DER encoding does not follow the prescribed format.
  - Oid
```
public Oid(byte[] DEROid)
    throws GSSException
```
    Constructs an Oid object from its DER encoding. The structure and encoding of Oids is defined in ISOIEC-8824 and ISOIEC-8825.
    
    Parameters:
    
    DEROid - a byte array containing the DER encoding of the 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"

    toRFC2078String()
  - toRFC2078String
```
public java.lang.String toRFC2078String()
```
    Returns a string representation of the Oid's integer components in the format specified within RFC 2078. For example { 1 2 3 4 }
    RFC 2078
    equivalent to gss_oid_to_str
    
    Returns:
    
    string representation in the following format: { 1 2 3 4 5 }
    
    See Also:
    
    toString()
  - equals
```
public boolean equals(java.lang.Object Obj)
```
    Equality test for oid objects.
    
    Overrides:
    
    equals in class java.lang.Object
    
    Parameters:
    
    Obj - Oid object that has to be compared to this one
    
    Returns:
    
    true if they represent the same Oid, false otherwise
  - getDER
```
public byte[] getDER()
              throws GSSException
```
    Returns the full ASN.1 DER encoding for this oid object.
    
    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 which takes an array of Oids and checks if it contains this oid object.
    RFC 2078
    In the JGSS package Oid sets are represented as arrays of Oids. This method is equivalent to gss_test_oid_set_member.
    
    Parameters:
    
    An - array of Oids to search
    
    Returns:
    
    true if the array contains this object, false otherwise
