    • Method Detail

      • getPadBits

        protected static int getPadBits​(int bitString)
        Parameters:
        bitString - an int containing the BIT STRING
        Returns:
        the correct number of pad bits for a bit string defined in a 32 bit constant

      • getBytes

        protected static byte[] getBytes​(int bitString)
        Parameters:
        bitString - an int containing the BIT STRING
        Returns:
        the correct number of bytes for a bit string defined in a 32 bit constant

      • getInstance

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

      • getInstance

        public static DERBitString getInstance​(ASN1TaggedObject obj,
                                       boolean explicit)
        return a Bit String 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:
        a DERBitString instance, or null.
        Throws:
        IllegalArgumentException - if the tagged object cannot be converted.

      • getBytes

        public byte[] getBytes()

      • getPadBits

        public int getPadBits()

      • intValue

        public int intValue()
        Returns:
        the value of the bit string as an int (truncating if necessary)

      • 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.
