* Constructor.
*
* @param positionPercent When the existing line is cut, percent is equal to the ratio between the parameters of the first line
* and the parameters of the line that is cut multiplied by 100. 100 minus percent is equal to the ratio
* between the parameters of the second line and the parameters of the line that is cut multiplied by 100.
* @param bbsOrBusId The ID of the existing bus or bus bar section of the voltage level voltageLevelId where we want to connect the line
* that will be between this voltage level and the fictitious voltage level.
* Please note that there will be switches between this bus or bus bar section and the connection point of the line.
* @param fictitiousVlId ID of the created voltage level at the attachment point of the initial line. Please note that this voltage level is fictitious.
* @param fictitiousVlName Name of the created voltage level at the attachment point of the initial line. Please note that this voltage level is fictitious.
* @param createFictSubstation If true, a fictitious substation at the attachment point will be created. Else, the created voltage level
* will be contained directly in the network.
* @param fictitiousSubstationId If createFictSubstation is true, the fictitious substation is given a non-null given ID.
* @param fictitiousSubstationName If createdFictSubstation is true, the fictitious substation is given a given name.
* @param line1Id When the initial line is cut, the line segment at side 1 has a non-null given ID.
* @param line1Name When the initial line is cut, the line segment at side 1 has a given name.
* @param line2Id When the initial line is cut, the line segment at side 2 has a non-null given ID.
* @param line2Name When the initial line is cut, the line segment at side 2 has a given name.
* @param line The initial line to be cut.
* @param lineAdder The line adder from which the line between the fictitious voltage level and the voltage level voltageLevelId is created.
* <p>
* NB: This constructor is package-private, please use {@link CreateLineOnLineBuilder} instead.
