Detailed Description

Structure that stores tree representation of map layer's legend.

This structure is used only when the following requirements are met:

tree legend representation is enabled in model (ShowLegendAsTree flag)

some legend nodes have non-null parent rule key (accessible via data(ParentRuleKeyRole) method)

The tree structure (parents and children of each node) is extracted by analyzing nodes' parent rules.
