Class ASN1ObjectIdentifier

    • Constructor Detail

      • ASN1ObjectIdentifier

        public ASN1ObjectIdentifier​(String identifier)
        Create an OID based on the passed in String.
        Parameters:
        identifier - a string representation of an OID.

    • Method Detail

      • getInstance

        public static ASN1ObjectIdentifier getInstance​(Object obj)
        return an OID from the passed in object
        Parameters:
        obj - an ASN1ObjectIdentifier or an object that can be converted into one.
        Returns:
        an ASN1ObjectIdentifier instance, or null.
        Throws:
        IllegalArgumentException - if the object cannot be converted.

      • getInstance

        public static ASN1ObjectIdentifier getInstance​(ASN1TaggedObject obj,
                                               boolean explicit)
        return an Object Identifier from a tagged object.
        Parameters:
        obj - the tagged object holding the object we want
        explicit - true if the object is meant to be explicitly tagged false otherwise.
        Returns:
        an ASN1ObjectIdentifier instance, or null.
        Throws:
        IllegalArgumentException - if the tagged object cannot be converted.

      • getId

        public String getId()
        Return the OID as a string.
        Returns:
        the string representation of the OID carried by this object.

      • branch

        public ASN1ObjectIdentifier branch​(String branchID)
        Return an OID that creates a branch under the current one.
        Parameters:
        branchID - node numbers for the new branch.
        Returns:
        the OID for the new created branch.

      • on

        public boolean on​(ASN1ObjectIdentifier stem)
        Return true if this oid is an extension of the passed in branch, stem.
        Parameters:
        stem - the arc or branch that is a possible parent.
        Returns:
        true if the branch is on the passed in stem, false otherwise.

      • getBody

        protected byte[] getBody()

      • hashCode

        public int hashCode()
        Description copied from class: Object
        Returns an integer hash code for this object. By contract, any two objects for which Object.equals(java.lang.Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

        Note that hash values must not change over time unless information used in equals comparisons also changes.

        See Writing a correct hashCode method if you intend implementing your own hashCode method.

        Specified by:
        hashCode in class ASN1Primitive
        Returns:
        this object's hash code.
        See Also:
        Object.equals(java.lang.Object)

      • toString

        public String toString()
        Description copied from class: Object
        Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression: 
           getClass().getName() + '@' + Integer.toHexString(hashCode())

        See Writing a useful toString method if you intend implementing your own toString method.

        Overrides:
        toString in class Object
        Returns:
        a printable representation of this object.
