Class ObjectIdentifier

java.lang.Object

com.tencent.kona.sun.security.util.ObjectIdentifier

All Implemented Interfaces:

java.io.Serializable

public final class ObjectIdentifier
extends java.lang.Object
implements java.io.Serializable

Represent an ISO Object Identifier.

Object Identifiers are arbitrary length hierarchical identifiers. The individual components are numbers, and they define paths from the root of an ISO-managed identifier space. You will sometimes see a string name used instead of (or in addition to) the numerical id. These are synonyms for the numerical IDs, but are not widely used since most sites do not know all the requisite strings, while all sites can parse the numeric forms.

So for example, JavaSoft has the sole authority to assign the meaning to identifiers below the 1.3.6.1.4.1.42.2.17 node in the hierarchy, and other organizations can easily acquire the ability to assign such unique identifiers.

Constructor Detail

ObjectIdentifier

public ObjectIdentifier(DerInputStream in)
                 throws java.io.IOException

Reads an ObjectIdentifier from a DerInputStream.

Parameters:

in - the input stream

Throws:

java.io.IOException - if there is an encoding error

Method Detail

of

public static ObjectIdentifier of(java.lang.String oidStr)
                           throws java.io.IOException

Returns an ObjectIdentifier instance for the specific String. If the String is not a valid OID string, an IOException is thrown.

Throws:

java.io.IOException

of

public static ObjectIdentifier of(KnownOIDs o)

Returns an ObjectIdentifier instance for the specific KnownOIDs.

equals

public boolean equals(java.lang.Object obj)

Compares this identifier with another, for equality.

Overrides:

equals in class java.lang.Object

Returns:

true iff the names are identical.

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Returns a string form of the object ID. The format is the conventional "dot" notation for such IDs, without any user-friendly descriptive strings, since those strings will not be understood everywhere.

Overrides:

toString in class java.lang.Object
