    • Constructor Detail

      • ASN1ObjectIdentifier

        public ASN1ObjectIdentifier​(java.lang.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​(java.lang.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:
        java.lang.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:
        java.lang.IllegalArgumentException - if the tagged object cannot be converted.

      • getId

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

      • branch

        public ASN1ObjectIdentifier branch​(java.lang.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.

      • toString

        public java.lang.String toString()
        Overrides:
        toString in class java.lang.Object

      • intern

        public ASN1ObjectIdentifier intern()
        Intern will return a reference to a pooled version of this object, unless it is not present in which case intern will add it.

        The pool is also used by the ASN.1 parsers to limit the number of duplicated OID objects in circulation.

        Returns:
        a reference to the identifier in the pool.
