Walks through an AST or model structure and collects all unique AST node classes encountered. Non-AST objects are ignored.
Examples
m <- example_models$energyRt$multimod
collect_ast_classes(m$equations$eqTechSng2Sng)
#> [1] "mm_equation" "dims" "symbol" "mm_mapping" "mm_variable"
#> [6] "expression" "mm_parameter"
# All node classes used anywhere in the model
collect_ast_classes(m)
#> [1] "mm_set" "mm_mapping" "dims" "symbol" "mm_parameter"
#> [6] "mm_variable" "mm_equation" "expression" "func" "when"
#> [11] "constant" "unary"
