Abstraction Functions

Abstraction Functions Documentation

Here you can read descriptions about the core instance methods used by the abstraction functionality of the radar template rule syntax.

See How to write templates

ASTNode

to_result(self)

Converts the current node and its children into a dictionary format suitable for serialization and further processing as a finding result location.

---

find_by_parent(self, parent_ident: str) -> ASTNodeList

Finds all nodes whose parent has the specified identifier and returns them as an ASTNodeList.

---

find_chained_calls(self, *idents: tuple[str, ...]) -> ASTNodeListGroup

Finds sequences of sequential nodes matching the specified identifiers and returns them as an ASTNodeListGroup.

---

find_by_access_path(self, access_path: str, keyword: str) -> ASTNodeList

Finds nodes whose access_path contains the specified keyword within the specified access path and returns them as an ASTNodeList.

access_path is a value representing the sequence of AST nodes walked until indexing of the node, that did not get indexed (due to not being a prime node).

---

find_comparisons_between(self, ident1: str, ident2: str)

Finds binary comparisons between the specified identifiers within the AST and returns them as an ASTNodeList.

---

find_comparison_involving(self, ident: str)

Finds any node involved in a comparison with the specified identifier and returns them as an ASTNodeList.

---

find_negative_of_operation(self, operation_name: str, *args: tuple) -> ASTNodeList

Finds nodes that do not match the results of the specified operation and returns them as an ASTNodeList.

"operation" refers to an ASTNode instance method.

---

find_functions_by_names(self, *function_names: tuple[str, ...]) -> ASTNodeList

Finds function nodes that match any of the specified function names and returns them as an ASTNodeList.

---

find_by_names(self, *idents: tuple[str, ...]) -> ASTNodeList

Finds nodes that match any of the specified identifiers within the AST and returns them as an ASTNodeList.

---

find_method_calls(self, caller: str, method: str) -> ASTNodeList

Finds method call nodes where the caller matches the specified identifier and the method name matches the specified method and returns them as an ASTNodeList.

---

find_assignments(self, ident: str, value_ident: str) -> ASTNodeList

Finds assignment nodes where the left-hand side matches the specified identifier and the right-hand side matches the specified value identifier and returns them as an ASTNodeList.

---

find_mutables(self) -> ASTNodeList

Finds nodes marked as mut: true within the AST and returns them as an ASTNodeList.

---

find_account_typed_nodes(self, ident: str) -> ASTNodeList

Finds nodes that are Account-typed based on their access_path and parent identifier and returns them as an ASTNodeList.

---

find_member_accesses(self, ident: str) -> ASTNodeList

Finds nodes that represent member accesses matching the specified identifier within the AST and returns them as an ASTNodeList.

ASTNodeList, ASTNodeListGroup

first(self)

Returns the first node in the list or calls exit_on_none if the list is empty.

---

to_result(self)

Converts each node in the list to its dictionary representation and returns the list of these representations, in a format suitable for serialization and further processing as a finding result location.

---

exit_on_none(self)

Raises a StopIteration exception if the list is empty. Allows wrapping a for loop iteration within try/except, and continue to the next iteration when the return value of the previous function is None.

exit_on_value(self)

Raises a StopIteration exception if the list contains any nodes. Allows wrapping a for loop iteration within try/except, and continue to the next iteration when the return value of the previous function has results.
