Callables.with_signatures()

with_signatures(signatures: List[str]) → Callables

Adds a filter to get callables that have any of the given signatures. Returns a filtered Callables child object. This method can be called on all Callables child classes: Functions and Modifiers.

To filter given a single signature, refer to Callables.with_signature().

Functions Example

from glider import *

def query():
  # Retrieve all functions that have `approve(address)` or `claim(address,uint256)` as signatures
  functions = Functions() \
      .with_signatures([
          "approve(address)",
          "claim(address,uint256)"
      ]) \
      .exec(100)

  # Return the first five functions
  return functions[0:5]

Output:

[
    {
        "contract": "0xb0d5eAC91C77997647875B9A72d5Bff1e78DAa78",
        "contract_name": "Arb",
        "sol_function": "function approve(address bamm) external {\n        ERC20Like(LUSD).approve(address(bamm),uint(-1));\n    }"
    },
    {

        "contract_name": "IRegistry",
        "sol_function": "function approve(address _addr) external;"
    },
    {
        "contract": "0x1c45e40a948bB9B4684B94239d5FD73e3a9cAD8A",
        "contract_name": "Registry",
        "sol_function": "function approve(address _addr) external override onlyOwner {\n        require(!_approved[_addr],\"_addr approved\");\n        _approved[_addr] = true;\n        emit Approve(_addr);\n    }"
    }
]

Modifiers Example

from glider import *

def query():
  # Retrieve all the modifiers that have `nonReentrant()` or `initializer()` as their signatures
  modifiers = Modifiers() \
    .with_signatures([
      "nonReentrant()",
      "initializer()"
    ]) \
    .exec(100)

  # Return the first five modifiers
  return modifiers[0:5]

Output:
