      • increment

        AddressSegmentSeries increment​(long increment)
                                throws AddressValueException
        Returns the series from the subnet that is the given increment upwards into the subnet range, with the increment of 0 returning the first address in the range.

        If the subnet has multiple values and the increment exceeds the subnet size, then the amount by which it exceeds the size - 1 is added to the upper series of the range (the final iterator value).

        If the increment is negative, it is added to the lower series of the range (the first iterator value).

        If the subnet is just a single address values, the series is simply incremented by the given value, positive or negative.

        If a subnet has multiple values, a positive increment value is equivalent to the same number of values from the iterator() For instance, a increment of 0 is the first value from the iterator, an increment of 1 is the second value from the iterator, and so on. A negative increment added to the subnet count is equivalent to the same number of values preceding the upper bound of the iterator. For instance, an increment of count - 1 is the last value from the iterator, an increment of count - 2 is the second last value, and so on.

        An increment of size count gives you the series just above the highest series of the subnet. To get the series just below the lowest series of the subnet, use the increment -1.

        Parameters:
        increment -
        Returns:
        Throws:
        AddressValueException - in case of underflow or overflow
      • incrementBoundary

        AddressSegmentSeries incrementBoundary​(long increment)
                                        throws AddressValueException
        If the given increment is positive, adds the value to the upper series (getUpper()) in the subnet range to produce a new series. If the given increment is negative, adds the value to the lower series (getLower()) in the subnet range to produce a new series. If the increment is zero, returns this.

        In the case where the series is a single value, this simply returns the address produced by adding the given increment to this address series.

        Parameters:
        increment -
        Returns:
        Throws:
        AddressValueException - in case of underflow or overflow
      • toCanonicalString

        Returns:
      • toCompressedString

        java.lang.String toCompressedString()
        Produces a short representation of the address while remaining within the confines of standard representation(s) of the address
        Returns:
      • reverseBits

        AddressSegmentSeries reverseBits​(boolean perByte)
        Returns a new segment series with the bits reversed.
        Specified by:
        reverseBits in interface AddressComponent
        Parameters:
        perByte - if true, only the bits in each byte are reversed, if false, then all bits in the component are reversed
        Returns:
        Throws:
        IncompatibleAddressException - if reversing the bits within a single segment cannot be done because the segment represents a range, and when all values in that range are reversed, the result is not contiguous. In practice this means that to be reversible the range must include all values except possibly the largest and/or smallest.
      • reverseBytes

        AddressSegmentSeries reverseBytes()
        Returns a new segment series with the bytes reversed.
        Specified by:
        reverseBytes in interface AddressComponent
        Returns:
        Throws:
        IncompatibleAddressException - if the segments have more than 1 bytes, and if reversing the bits within a single segment cannot be done because the segment represents a range that is not the entire segment range.
      • reverseBytesPerSegment

        AddressSegmentSeries reverseBytesPerSegment()
        Returns a new segment series with the bytes reversed within each segment.
        Returns:
        Throws:
        IncompatibleAddressException - if the segments have more than 1 bytes, and if reversing the bits within a single segment cannot be done because the segment represents a range that is not the entire segment range.
      • toPrefixBlock

        AddressSegmentSeries toPrefixBlock()
        If this series has a prefix length, returns the block for that prefix. Otherwise, this address series is returned.
        Returns:
        the block of address series for the prefix length
      • withoutPrefixLength

        AddressSegmentSeries withoutPrefixLength()
        Provides the same address with no prefix. The values remain unchanged.

        Use removePrefixLength() as an alternative that deletes the host at the same time by zeroing the host values.

      • adjustPrefixBySegment

        AddressSegmentSeries adjustPrefixBySegment​(boolean nextSegment)
        Increases or decreases prefix length to the next segment boundary.

        Follows the same rules as adjustPrefixLength(int):
        When prefix length is increased, the bits moved within the prefix become zero. When a prefix length is decreased, the bits moved outside the prefix become zero. To avoid the zeroing behaviour, use adjustPrefixBySegment(boolean, boolean) with second arg false.

        Parameters:
        nextSegment - whether to move prefix to previous or following segment boundary
        Returns:
      • adjustPrefixBySegment

        AddressSegmentSeries adjustPrefixBySegment​(boolean nextSegment,
                                                   boolean zeroed)
        Increases or decreases prefix length to the next segment boundary.
        Parameters:
        nextSegment - whether to move prefix to previous or following segment boundary
        zeroed - whether the bits that move from one side of the prefix to the other become zero or retain their original values
        Returns:
      • adjustPrefixLength

        AddressSegmentSeries adjustPrefixLength​(int adjustment)
        Increases or decreases prefix length by the given increment.

        When prefix length is increased, the bits moved within the prefix become zero. When the prefix is extended beyond the segment series boundary, it is removed. When a prefix length is decreased, the bits moved outside the prefix become zero. To avoid the zeroing behaviour, use adjustPrefixLength(int, boolean) with second arg false.

        Parameters:
        adjustment -
        Returns:
      • adjustPrefixLength

        AddressSegmentSeries adjustPrefixLength​(int adjustment,
                                                boolean zeroed)
        Increases or decreases prefix length by the given increment.
        Parameters:
        zeroed - whether the bits that move from one side of the prefix to the other become zero or retain their original values
        adjustment - the increment
        Returns:
      • setPrefixLength

        AddressSegmentSeries setPrefixLength​(int prefixLength)
        Sets the prefix length.

        If this series has a prefix length, and the prefix length is increased, the bits moved within the prefix become zero. For an alternative that does not set bits to zero, use setPrefixLength(int, boolean) with the second argument as false.

        When the prefix is extended beyond the segment series boundary, it is removed.

        The bits that move from one side of the prefix length to the other (ie bits moved into the prefix or outside the prefix) are zeroed.

        Parameters:
        prefixLength -
        Returns:
      • setPrefixLength

        AddressSegmentSeries setPrefixLength​(int prefixLength,
                                             boolean zeroed)
        Sets the prefix length.

        When the prefix is extended beyond the segment series boundary, it is removed.

        Parameters:
        zeroed - whether the bits that move from one side of the prefix length to the other (ie bits moved into the prefix or outside the prefix) are zeroed.
        Returns:
      • applyPrefixLength

        @Deprecated
        AddressSegmentSeries applyPrefixLength​(int prefixLength)
        Deprecated.
        use #setPrefixLength(int)
        Applies the given prefix length to create a new segment series.

        Similar to setPrefixLength(int) except that prefix lengths are never increased. When this series already has a prefix length that is less than or equal to the requested prefix length, this series is returned.

        Otherwise the returned series has the given prefix length.

        The bits moved outside the prefix will become zero in the returned series.

        Parameters:
        prefixLength -
        Returns:
