We are in the case where the two attributes are non `nullptr`, thus the first one is kept, and all the darts of c2 are associated with the first attribute. \cgalFigureEnd The \link CombinatorialMap::sew `sew(dh1,dh2)`\endlink method consists mainly to link two by two several darts by \f$ \beta_i\f$. This operation is possible only if there is a bijection f between all the darts of the orbit D1=\f$ \langle{}\f$\f$ \beta_1\f$,...,\f$ \beta_{i-2}\f$,\f$ \beta_{i+2}\f$,...,\f$ \beta_d\f$\f$ \rangle{}\f$(d1) and D2=\f$ \langle{}\f$\f$ \beta_1\f$,...,\f$ \beta_{i-2}\f$,\f$ \beta_{i+2}\f$,..., \f$ \beta_d\f$\f$ \rangle{}\f$(d2) satisfying: f(d1)=d2, and for all e\f$ \in \f$ D1, for all j\f$ \in \f${1,..., i-2,i+2,...,d}, f(\f$ \beta_j\f$(e))=\f$ \beta_j^{-1}\f$(f(e)). Intuitively, this condition ensures the validity of the combinatorial map by verifying that condition discussed in Section \ref sseccombimapvalidity "Combinatorial Map Properties" will be satisfied after the operation. This condition can be tested by using the method \link CombinatorialMap::is_sewable `is_sewable(dh1,dh2)`\endlink. For example, the function \link CombinatorialMap::is_sewable `is_sewable<3>`\endlink would return `false` if we tried to 3-sew a triangular facet with a quad facet. Note that given two darts d1 and d2, if there is such a bijection, it is uniquely defined. So giving the two darts as arguments of the \link CombinatorialMap::sew `sew`\endlink is enough to retrieve all the pairs of darts to link. If such a bijection exists, the \link CombinatorialMap::sew `sew(dh1,dh2)`\endlink operation consists only in linking by \f$ \beta_i\f$ each couple of darts d3 and d4 such that d3=f(d4). -In addition, the sew operation updates the associations between darts and non void attributes in order to guarantee that all the darts belonging to a given cell are associated with the same attribute (which is a condition of combinatorial map validity). For each couple of j-cells c1 and c2 that are merged into one j-cell during the sew, we have to update the two associated attributes attr1 and attr2. If both are NULL, there is nothing to do. If one is NULL and the other not, we only associate the non NULL attribute to all the darts of the resulting cell. When the two attributes are non NULL, we first apply functor \link CellAttribute::On_merge `On_merge`\endlink on the two attributes attr1 and attr2 (see Section \ref ssecattributes "Cell Attributes"). Then, we associate the attribute attr1 to all darts of the resulting j-cell. Finally, attribute attr2 is removed from the combinatorial map. +In addition, the sew operation updates the associations between darts and non void attributes in order to guarantee that all the darts belonging to a given cell are associated with the same attribute (which is a condition of combinatorial map validity).

But user can customize this behavior in order to update the information contained in the attributes according to its needs. For that, we can define a specific functor, and use it as template argument for \link CellAttribute::On_merge `On_merge`\endlink parameter of the `Cell_attribute` definition. This functor can for example copy the information of the second attribute in the information of the first one to make as if the second attribute is kept. +Note that when the two attributes are non `nullptr`, the first one is kept.

We are in the case where the two attributes are non `nullptr`, thus the first one is kept, and all the darts of c2 are associated with the first attribute. \cgalFigureEnd The \link GeneralizedMap::sew `sew(dh1,dh2)`\endlink method consists mainly to link two by two several darts by \f$ \alpha_i\f$. This operation is possible only if there is a bijection f between all the darts of the orbit D1=\f$ \langle{}\f$\f$ \alpha_1\f$,...,\f$ \alpha_{i-2}\f$,\f$ \alpha_{i+2}\f$,...,\f$ \alpha_d\f$\f$ \rangle{}\f$(d1) and D2=\f$ \langle{}\f$\f$ \alpha_1\f$,...,\f$ \alpha_{i-2}\f$,\f$ \alpha_{i+2}\f$,..., \f$ \alpha_d\f$\f$ \rangle{}\f$(d2) satisfying: f(d1)=d2, and for all e \f$ \in \f$ D1, for all j \f$ \in \f$ {1,..., i-2,i+2,...,d}, f(\f$ \alpha_j\f$(e))=\f$ \alpha_j^{-1}\f$(f(e)). Intuitively, this condition ensures the validity of the generalized map by verifying that condition discussed in Section \ref ssecgenmapvalidity "Generalized Map Properties" will be satisfied after the operation. This condition can be tested by using the method \link GeneralizedMap::is_sewable `is_sewable(dh1,dh2)`\endlink. For example, the function \link GeneralizedMap::is_sewable `is_sewable<3>`\endlink would return `false` if we tried to 3-sew a triangular facet with a quad facet. Note that given two darts d1 and d2, if there is such a bijection, it is uniquely defined. So giving the two darts as arguments of the \link GeneralizedMap::sew `sew`\endlink is enough to retrieve all the pairs of darts to link. If such a bijection exists, the \link GeneralizedMap::sew `sew(dh1,dh2)`\endlink operation consists only in linking by \f$ \alpha_i\f$ each couple of darts d3 and d4 such that d3=f(d4). -In addition, the sew operation updates the associations between darts and non void attributes in order to guarantee that all the darts belonging to a given cell are associated with the same attribute (which is a condition of generalized map validity). For each couple of j-cells c1 and c2 that are merged into one j-cell during the sew, we have to update the two associated attributes attr1 and attr2. If both are NULL, there is nothing to do. If one is NULL and the other not, we only associate the non NULL attribute to all the darts of the resulting cell. When the two attributes are non NULL, we first apply functor \link CellAttribute::On_merge `On_merge`\endlink on the two attributes attr1 and attr2 (see Section \ref ssecattributesgmap "Cell Attributes"). Then, we associate the attribute attr1 to all darts of the resulting j-cell. Finally, attribute attr2 is removed from the generalized map. +In addition, the sew operation updates the associations between darts and non void attributes in order to guarantee that all the darts belonging to a given cell are associated with the same attribute (which is a condition of generalized map validity).

But user can customize this behavior in order to update the information contained in the attributes according to its needs. For that, we can define a specific functor, and use it as template argument for \link CellAttribute::On_merge `On_merge`\endlink parameter of the `Cell_attribute` definition. This functor can for example copy the information of the second attribute in the information of the first one to make as if the second attribute is kept. +Note that when the two attributes are non `nullptr`, the first one is kept.
