com.streamconverter.path.TreePath
All Implemented Interfaces:
IPath<List<String>>
public class TreePath extends Object implements IPath<List<String>>
Represents a hierarchical path for tree-like data structures (JSON, XML).

This class handles parsing and matching of path expressions in both JSON-style ("$.user.name") and XML-style ("user/name") formats. It converts path expressions into hierarchical segments for efficient matching during data processing.
