Build DISPATCHES_ON and EXTENDS edges for OOP patterns

Scans R source files for S4 generics/methods, R5 reference classes, and R6 classes. Emits:

EXTENDS

From child class node to parent, detected via setClass(contains=), R6Class(inherit=), and setRefClass(contains=).

DISPATCHES_ON

From a concrete S4 method node to the corresponding generic node when both appear in the parsed node set.

Usage

build_dispatch_edges(func_nodes, r_files)

Arguments

func_nodes

A list of node records from extract_function_nodes().

r_files

Character vector of absolute paths to .R source files.

Value

A data.frame with columns from, to, weight, and edge_type. Zero rows when no OOP patterns are detected.

Examples

if (FALSE) { # \dontrun{
proj  <- detect_rproject("/path/to/mypkg")
nodes <- extract_function_nodes(proj$r_files)
edges <- build_dispatch_edges(nodes, proj$r_files)
} # }
