Removes the i-cell containing dh.
Returns the number of darts removed from cm.
| Precondition: | is_removable<CMap,i>(cm,dh).
See examples in Figures 27.11, 27.13 and 27.14.
If i<CMap::dimension, and i+1-attributes are
non void, and if there are two distinct (i+1)-cells around dart
dh, Attribute_type<i+1>::type::On_merge(a1,a2) is
called, with a1 the (i+1)-attribute associated to dh,
and a2 the (i+1)-attribute associated to βi+1(dh).
If a j-cell is disconnected in two j-cells during the
operation, and if j-attributes are non void,
Attribute_type<j>::type::On_split(a,a') is called
with a the original j-attribute and a' the new
j-attribute created due to the disconnection. |
