32 * This is the support class for store/retrieve differences of undo/redo
33 * operations. To fill the difference it is necessary to create it with
34 * an appropriate type and to call the method initialize with required
37 class CurveCreator_Diff
55 * This method initializes the difference with an operation without
56 * parameters. It is applicable to the following operations:
59 * <LI>Join (without arguments)</LI>
62 bool init(const CurveCreator_Curve *theCurve,
63 const CurveCreator_Operation::Type theType);
66 * This method initializes the difference with an operation with one integer
67 * parameter. It is applicable to the following operations:
69 * <LI>RemoveSection</LI>
72 bool init(const CurveCreator_Curve *theCurve,
73 const CurveCreator_Operation::Type theType,
74 const int theIntParam);
77 * This method initializes the difference with an operation with two integer
78 * parameters. It is applicable to the following operations:
82 * <LI>MoveSection</LI>
83 * <LI>Join (with 2 int arguments)</LI>
86 bool init(const CurveCreator_Curve *theCurve,
87 const CurveCreator_Operation::Type theType,
88 const int theIntParam1,
89 const int theIntParam2);
92 * This method initializes the difference with an operation with three
93 * integer parameters. It is applicable to the following operations:
95 * <LI>RemovePoints</LI>

99 const CurveCreator_Operation::Type theType,
100 const int theIntParam1,
101 const int theIntParam2,
102 const int theIntParam3);
105 * This method initializes the difference with an operation with one
106 * CurveCreator::Coordinates parameter and one integer parameter.
107 * It is applicable to the following operations:
112 bool init(const CurveCreator_Curve *theCurve,
113 const CurveCreator_Operation::Type theType,
114 const CurveCreator::Coordinates &theCoords,
115 const int theIntParam);
118 * This method initializes the difference with an operation with one
119 * CurveCreator::Coordinates parameter and two integer parameters.
120 * It is applicable to the following operations:
122 * <LI>InsertPoints</LI>
123 * <LI>SetCoordinates</LI>

127 const CurveCreator_Operation::Type theType,
128 const CurveCreator::Coordinates &theCoords,

133 * This method initializes the difference with an operation with one
134 * Name, one CurveCreator::Coordinates parameter and two integer parameters.
135 * It is applicable to the following operations:
137 * <LI>AddSection</LI>
140 bool init(const CurveCreator_Curve *theCurve,

149 * string and one integer parameters.

152 * <LI>RenameSection</LI>

166 * This method applies redo operation to theCurve.

173 * This method clears initialized data pointers.
178 * This method sets the number of undos and allocates the required
181 void setNbUndos(const int theNbUndos);
184 * This method returns the section index. It returns theIndex if it is
185 * a real index and the last section's index if theIndex is equal to -1.

192 * and store it in theOperation. Returns true in case of success and

200 * Construct undos for SetType and SetClosed operations. Note: the
201 * algorithm is optimized taking into account that there are only 2 types
202 * and 2 values of isClosed flag. If the number of types is increased,
203 * this algorithm should be re-implemented.
