Detailed Description

The vtkQtChartIndexRangeList class stores a searchable list of index ranges.

A modified red-black binary tree is used to store the ranges. The red/black flag on each node is used to keep the tree balanced. Each parent node holds the combined range of the two children. The leaf nodes contain the list of actual ranges. The navigation and search methods provide an interface to the leaf nodes.

Returns:: A pointer to the first index range or null if the list is empty.

vtkQtChartIndexRange* vtkQtChartIndexRangeList::getLast ( ) const

Gets the last index range in the list.

Returns:: A pointer to the last index range or null if the list is empty.

vtkQtChartIndexRange* vtkQtChartIndexRangeList::getNext ( vtkQtChartIndexRange * range ) const

Gets the next index range in the list.

Parameters:

range The index range to search from.
