Protected Member Functions | |
| virtual int | queryIndex (const GmCell *c) const =0 |
| A virtual function that given a cell returns the index that should be accessed. | |
| Protected Member Functions inherited from GmCellAccessorProxy | |
| void | saveCellInContext (const GmCell *c, int ip) const |
| A function that given a cell, saves it in the context. The ip parameter should store the integration point index equivalent to the coordinate passed to the function evaluation or -1 if this is not an integration point or the information is unavailable (in that case the function evaluation will try to find out which integration point is equivalent to a coordinate, if necessary, but that takes some effort) | |
| Protected Member Functions inherited from GmAccessorProxy | |
| double | convertToAccessorUnit (double val) const |
| An utility function that given a value, converts it to the accessor unit. If no conversion is needed, returns val. | |
| const double * | convertToAccessorUnit (const double *p) const |
| An utility function that given a pointer to the stored data, converts the value to the accessor unit and returns a pointer to the internal buffer used to store the converted value. If no conversion is needed, returns p. | |
| void | convertFromAccessorUnit (double val, double *dst) const |
| Copies the value given by val into the area pointed to by dst, converting units if needed. | |
| void | convertFromAccessorUnit (const double *val, double *dst) const |
| Copies the values given by val into the area pointed to by dst, converting units if needed. | |

The GmCellAccessor class is a proxy object to a value accesor implementing a more convenient interface where indices used to retrieve / store values are replaced by a reference to a cell.
This is a pure virtual class that should have its query method reimplemented in derived classes to treat the different cases that appear when treating attribute or property accessors.
