Overview

Extracts operations from a method body AST in source line order.

Uses Ast::CallSiteExtractor for raw call sites, then classifies each into domain-meaningful operation types: calls, transactions, async enqueues, responses, conditionals, cycles, and dynamic dispatch.

Examples:

Extracting operations from a method body

parser = Ast::Parser.new
root = parser.parse(source)
method_node = root.find_all(:def).find { |n| n.method_name == "create" }
ops = OperationExtractor.new.extract(method_node)
ops.first[:type] #=> :call
