Overview

Point class that works as both a Hash and an object with row/column accessors

This provides compatibility with code expecting either:

  • Hash access: point, point

  • Method access: point.row, point.column

Examples:

Method access

point = TreeHaver::Point.new(5, 10)
point.row    # => 5
point.column # => 10

Hash-like access

point[:row]    # => 5
point[:column] # => 10

Converting to hash

point.to_h # => {row: 5, column: 10}
