Detailed Description

Cell group set consisting of a set of mesh cell groups.

Cells will be traversed in cell id order

Member Function Documentation

applyTransform()

void GmCellGenericGroupSet::applyTransform ( std::function< int(int)> & t )

virtual

This is a very specialized function. Use only if you know what you are doing. For sets storing internally the cell ids, it should apply the given transformation to every id, replacing the previous ones. Sets that just point to cell groups should do nothing.

Implements GmCellGroupSet.

cell()

virtual GmCell * GmCellGenericGroupSet::cell ( int setIndex ) const

inlinevirtual

Given an index in the range [0..numCells()-1], returns the respective cell.

Implements GmCellGroupSet.

clear()

void GmCellGenericGroupSet::clear ( )

virtual

Clear the group set in response to a mesh clear() operation. It will not clear the list of cellGroups.

Reimplemented from GmBaseCellGroupSet.

numCells()

virtual int GmCellGenericGroupSet::numCells ( ) const

inlinevirtual

Returns the number of unique elements in the cell group set.

Implements GmCellGroupSet.

ordered()

virtual bool GmCellGenericGroupSet::ordered ( ) const

inlinevirtual

Returns true if the the set returned by calls to cell(0) through cell(numCells()-1) is ordered by cell id.

Implements GmCellGroupSet.

usedMemory()

virtual size_t GmCellGenericGroupSet::usedMemory ( ) const

inlinevirtual

Returns the approximate amount of memory used to store node data, if any.

Reimplemented from GmBaseCellGroupSet.
