Callable.catch_instructions()

Returns catch instructions of the function/modifier.

catch_instructions() → Instructions

Example

from glider import *
def query():
  functions = Functions().exec(400)

  catch_instructions = []
  for function in functions:
    # List all catch instructions inside a try/catch block from the given functions
    for instruction in function.catch_instructions().exec():
      catch_instructions.append(instruction)

  return catch_instructions
