In the case where the prefix sits at a segment boundary, and the prefix sequence is null - null - 0, this changes to prefix sequence of null - x - 0, where x is segment bit length. Note: We allow both [null, null, 0] and [null, x, 0] where x is segment length. However, to avoid inconsistencies when doing segment replacements, and when getting subsections, in the calling constructor we normalize [null, null, 0] to become [null, x, 0]. We need to support [null, x, 0] so that we can create subsections and full addresses ending with [null, x] where x is bit length. So we defer to that when constructing addresses and sections. Also note that in our append/appendNetowrk/insert/replace we have special handling for cases like inserting [null] into [null, 8, 0] at index 2. The straight replace would give [null, 8, null, 0] which is wrong. In that code we end up with [null, null, 8, 0] by doing a special trick: We remove the end of [null, 8, 0] and do an append [null, 0] and we'd remove prefix from [null, 8] to get [null, null] and then we'd do another append to get [null, null, null, 0] The final step is this normalization here that gives [null, null, 8, 0] However, when users construct AddressDivisionGrouping or IPAddressDivisionGrouping, either one is allowed: [null, null, 0] and [null, x, 0]. Since those objects cannot be further subdivided with getSection/getNetworkSection/getHostSection or grown with appended/inserted/replaced, there are no inconsistencies introduced, we are simply more user-friendly. Also note that normalization of AddressDivisionGrouping or IPAddressDivisionGrouping is really not possible without the address creator objects we use for addresses and sections, that allow us to recreate new segments of the correct type. @param sectionPrefixBits @param segments @param segmentBitCount @param segmentByteCount @param segProducer
