CallNode.caller_functions()

Returns Functions object for the functions that call the current node corresponding function.

caller_functions() → Functions

Query Example

from glider import *

# task: find a function that has `burn*` call and return all the functions that has a call to that function

def query():
  data = []
  instructions = Instructions().with_callee_name_prefix('burn').exec(10)
  
  for instruction in instructions:
    if len(data) > 0:
      break # demo first result only
    functionContainsBurn = instruction.get_parent() #api.functions.Function (*)
    contract = functionContainsBurn.get_contract() #api.contracts.Contract
    call_graph = contract.call_graph() #api.call_graph.CallGraph 
    nodes = call_graph.nodes() #Dict[str, CallNode]
    
    for id in nodes:
      if(id != functionContainsBurn.db_id):
        continue
      caller_functions = nodes[id].caller_functions #api.functions.Functions
      callers = caller_functions().exec() #List[Function]
      if len(callers) > 0:
        print(functionContainsBurn.source_code())
        for caller in callers:
          print(caller.source_code())
        data.append(instruction)
        
  return data
