src/clp_ffi_js/ir/StructuredIrUnitHandler.hpp (4)

4-4: Added include for algorithm header.

The include for <algorithm> is properly added to support the use of std::ranges::reverse in the SchemaTreeFullBranch constructor.

---

28-84: Well-structured new class implementation.

The SchemaTreeFullBranch class is well-designed with clear documentation, proper move semantics, and deleted copy operations. The implementation correctly encapsulates a branch path from root to leaf in a schema tree.

A few observations:

• Constructor reverses the path for internal storage, which seems intentional for efficient tree traversal
• Good use of [[nodiscard]] attribute for methods that return values
• The declaration of match() method has its implementation elsewhere, following good separation practices

---

145-163: Documentation updated to reflect new optional member variables.

The documentation for both get_log_level and get_timestamp methods has been properly updated to reference the new optional member variables. This improves clarity on when default values are returned.

---

168-172: Renamed member variables for improved clarity.

The member variables have been renamed with the m_optional_ prefix to better reflect their purpose and type. This is a good practice that makes the code more self-documenting.

According to the past review comment on line 171-172, using std::optional explicitly follows the C++ coding convention for this project, which is good.

28-83: Well-structured new class for schema tree branch representation

The new SchemaTreeFullBranch class provides a clean way to represent branches from root to leaf node in a schema tree. This improves the handling of hierarchical log level and timestamp keys.

---

132-132: Good parameter choice for schema_tree

Passing the schema tree as a const reference to a shared pointer is efficient and appropriate for this use case.

---

167-171: Improved structure for storing branch information

Replacing simple string keys with full branch objects allows for more flexible and structured handling of hierarchical paths in the schema tree.

168-169: Good use of more descriptive variable names.

Renaming these variables to include optional_ in their names provides better clarity about their nature. This makes the code more maintainable by explicitly indicating that these variables might not have a value.

---

27-83: Well-structured new class implementation.

The SchemaTreeFullBranch class is a well-designed addition that encapsulates the concept of a branch in a schema tree. The class properly implements move semantics while preventing copies, and provides a clear interface for checking if a branch is auto-generated and matching against a schema tree.

---

126-133: Method parameter addition improves functionality.

Adding the schema_tree parameter to the handle_schema_tree_node_insertion method enables the functionality to match schema tree branches, which is essential for supporting the hierarchical keys feature described in the PR objectives.

src/clp_ffi_js/ir/StreamReader.hpp (1)

28-28: No concerns about new type declaration.

The addition of ReaderOption appears consistent and aligns with your existing types (DataArrayTsType, LogLevelFilterTsType). If there are no tests for the new type, consider adding a simple unit test to verify its usage and ensure future compatibility.

src/clp_ffi_js/ir/StructuredIrStreamReader.cpp (7)

6-15: Straightforward new includes.

Including <optional> and <clp/ffi/SchemaTree.hpp> is appropriate for the optional logic and schema-related functionality introduced. No issues observed.

---

32-33: Use of descriptive constant names.

Defining cReaderOptionIsAutoGeneratedKey and cReaderOptionPartsKey aligns with existing naming conventions. This helps ensure clarity when accessing the JS object properties.

---

46-47: Appropriate use of [[nodiscard]].

Marking dump_json_with_replace as [[nodiscard]] is a good practice to avoid inadvertently ignoring the returned string. No issues with this change.

---

63-75: Validate array content.

This function correctly handles null checks and extracts data from option. Consider additional validation for the parts array (e.g. ensuring the array is non-empty for a valid path) to avoid unexpected states in downstream logic.

---

99-106: Consistent usage of reader options.

Replacing direct string usage with calls to get_schema_tree_full_path_from_reader_option for both the log level and timestamp keys aligns with the PR objective. Good to see that log levels default to string type and timestamps default to integer type.

---

135-136: Consistent with coding guidelines.

Using if (false == ...) instead of if (!...) adheres to the project’s guidelines. The behaviour for returning null() when no filter map exists is clear.

---

160-161: Loop condition looks appropriate.

Looping until deserializer.is_stream_completed() is false is consistent. Just confirm that there are no edge cases that might lead to an infinite loop if the condition never evaluates to true.

src/clp_ffi_js/ir/StructuredIrUnitHandler.hpp (4)

4-4: New include is acceptable.

The <algorithm> header is presumably for std::ranges::reverse. This is fine.

---

94-99: Optional schema tree branches well-integrated.

Switching to std::optional<SchemaTreeFullBranch> for both log level and timestamp clarifies that these branches are optional. This is a clean approach that preserves the original constructor’s intent.

---

151-162: Documentation is consistent and clear.

The docstrings for get_log_level and get_timestamp correctly outline fallback behaviour. The usage of LogLevel::None for unexpected values is a commendable solution. Confirm that all out-of-range scenarios are handled.
[approve]

---

165-169: Optional node IDs.

Storing the node IDs as std::optional matches your approach for the full branch. This ensures you skip logic when the node IDs are unavailable.

32-33: String view constants should follow naming convention.

Consider using the constexpr std::string_view cFilterOptionAutoGeneratedKey{"isAutoGenerated"}; naming style to be more consistent with other constants in the file.

-constexpr std::string_view cFilterOptionIsAutoGeneratedKey{"isAutoGenerated"};
-constexpr std::string_view cFilterOptionPartsKey{"parts"};
+constexpr std::string_view cFilterOptionAutoGeneratedKey{"isAutoGenerated"};
+constexpr std::string_view cFilterOptionPartsKey{"parts"};

---

48-53: Improve documentation comments for get_schema_tree_full_branch_from_filter_option.

The documentation should clearly specify the leaf node type parameter and match the actual function signature.

 /**
  * @param filter_option The JavaScript object representing a filter option.
  * @param leaf_node_type The type of the leaf node in the constructed schema tree branch.
- * @return A schema tree full branch constructed based on the provided reader option.
+ * @return A schema tree full branch constructed based on the provided filter option and leaf node type.
  * @return std::nullopt if `option` is `null`.
  */

---

54-57: Function declaration could be formatted more consistently.

The closing parenthesis should be consistent with the opening parenthesis formatting style.

 [[nodiscard]] auto get_schema_tree_full_branch_from_filter_option(
         emscripten::val const& filter_option,
-        clp::ffi::SchemaTree::Node::Type leaf_node_type
-) -> std::optional<StructuredIrUnitHandler::SchemaTreeFullBranch>;
+        clp::ffi::SchemaTree::Node::Type leaf_node_type) 
+        -> std::optional<StructuredIrUnitHandler::SchemaTreeFullBranch>;

---

67-69: Check for both null and undefined for safety.

This is good defensive programming to check for both null and undefined values.

---

70-74: Using key constants correctly in the function implementation.

Make sure to use the constant variables defined above rather than hardcoding string literals.

     return StructuredIrUnitHandler::SchemaTreeFullBranch{
             filter_option[cFilterOptionIsAutoGeneratedKey.data()].as<bool>(),
             emscripten::vecFromJSArray<std::string>(filter_option[cFilterOptionPartsKey.data()]),
             leaf_node_type
     };

---

99-106: Function calls to get schema tree branches are well-structured.

The code correctly sets the appropriate node types for log level (string) and timestamp (integer) as required by the design.

src/clp_ffi_js/ir/StructuredIrUnitHandler.hpp (4)

94-96: Constructor parameters renamed correctly.

The parameters are appropriately renamed from string keys to schema branch objects, matching the updated implementation.

---

130-133: Added schema_tree parameter to handle_schema_tree_node_insertion.

This is a good improvement that provides the function with the necessary context to properly match full branches.

---

165-169: Renamed member variables for clarity.

The member variables have been renamed with the 'optional' prefix to better indicate their nature.

---

74-77:

❓ Verification inconclusive

Verify match method declaration.

The match method is declared but its implementation isn't in the header file. Ensure it's properly implemented in the corresponding .cpp file.

---

🏁 Script executed:

#!/bin/bash
# Check if the match method is implemented in the cpp file
grep -A 15 "auto SchemaTreeFullBranch::match" src/clp_ffi_js/ir/StructuredIrUnitHandler.cpp

Length of output: 93

Manual Verification Required: Confirm Implementation of the match Method

The current code in src/clp_ffi_js/ir/StructuredIrUnitHandler.hpp declares the match method, yet our grep search in src/clp_ffi_js/ir/StructuredIrUnitHandler.cpp using "auto SchemaTreeFullBranch::match" returned no results. This might indicate that the method is either not implemented or is defined under a different class name (e.g. StructuredIrUnitHandler::match). Please verify manually that:

• The implementation of match exists in src/clp_ffi_js/ir/StructuredIrUnitHandler.cpp.
• The implementation’s class name matches the header declaration (i.e. use StructuredIrUnitHandler if that is the intended class).
