SquarifiedPlusAlgorithm

Implementation of the Squarified+ algorithm. It is described in:

Cesarano A, Ferrucci F, Torre M. A heuristic extending the Squarified treemapping algorithm. arXiv preprint arXiv:1609.00754. 2016 Sep 2.

A heuristic extending the squarified algorithm with better aspect ratios and higher homogeneity among items.

Complexity: O(n), where n is the number of nodes in the tree.

open override fun <N, Row, Column> breadthFirstLayout(shape: Shape, parent: N, children: Array<N>, sumSize: Double, horizontalVanishingPoint: Int, verticalVanishingPoint: Int, accessor: TreeMapAccessor<N>, worker: TreeMapWorker?): Boolean

{@inheritDoc}

open override fun <N, Row, Column> depthFirstLayout(shape: Shape?, parent: N, children: Array<N>, sumSizes: Double, horizontalVanishingPoint: Int, verticalVanishingPoint: Int, accessor: TreeMapAccessor<N>, worker: TreeMapWorker?): Boolean

Arrange the items in the given array to fill the given shape. This is called during the first pass, while traversing the tree from the bottom up.

open override fun <N, Row, Column> finishLayout(bounds: Rectangle2D?, model: TreeMapModel<N, Row, Column>?, root: N)

Do nothing by default.

Link copied to clipboard
open override fun isCompatible(shape: Shape?): Boolean

Indicates whether the layout algorithm can handle the given geometry of its parent

open override fun <N, Row, Column> iterator(model: TreeMapModel<N, Row, Column>, root: N): Iterable<N>

Breadth first traversal by default.

Link copied to clipboard
open override fun <N, Row, Column> startLayout(bounds: Rectangle2D?, model: TreeMapModel<N, Row, Column>, root: N, worker: TreeMapWorker?)

Do nothing by default.
