levelToMaxDimensionMap	back to summary
private final Map<Integer, Double> levelToMaxDimensionMap A map storing the maximum dimension (either width or height based on the layout direction) for each level (or depth) in the tree. - For LEFT_TO_RIGHT or RIGHT_TO_LEFT layouts, it represents the maximum height for a particular depth or level. - For TOP_TO_BOTTOM or BOTTOM_TO_TOP layouts, it represents the maximum width for a particular depth or level. This map ensures that nodes on the same level do not overlap and provides consistent spacing across different layout directions.

levelToMaxDimensionMap

back to summary

private final Map<Integer, Double> levelToMaxDimensionMap

A map storing the maximum dimension (either width or height based on the layout direction) for each level (or depth) in the tree. - For LEFT_TO_RIGHT or RIGHT_TO_LEFT layouts, it represents the maximum height for a particular depth or level. - For TOP_TO_BOTTOM or BOTTOM_TO_TOP layouts, it represents the maximum width for a particular depth or level. This map ensures that nodes on the same level do not overlap and provides consistent spacing across different layout directions.

nodeTotalDimensionMap	back to summary
private final Map<TreeNode<T>, Double> nodeTotalDimensionMap A map storing the total dimension (either width or height based on the layout direction) of each node. - For LEFT_TO_RIGHT or RIGHT_TO_LEFT layouts, it represents the total height of a node, which includes the node itself and its maximum subtree height. - For TOP_TO_BOTTOM or BOTTOM_TO_TOP layouts, it represents the total width of a node, including the node and its maximum subtree width. The purpose of this map is to dynamically adapt to different layout directions and provide a consistent way to handle node dimensions.
