decodeLog

Callable

• decodeLog<ReturnType>(inputs: AbiParameter[], data: string, topics: string | string[]): ReturnType

---

• Decodes ABI-encoded log data and indexed topic data.

  @example

  let res = web3.eth.abi.decodeLog(
     [
       {
         type: "string",
         name: "myString",
       },
       {
         type: "uint256",
         name: "myNumber",
         indexed: true,
       },
       {
         type: "uint8",
         name: "mySmallNumber",
         indexed: true,
       },
     ],
     "0x0000000000000000000000000000000000000000000000000000000000000020000000000000000000000000000000000000000000000000000000000000000748656c6c6f252100000000000000000000000000000000000000000000000000",

   );
  > {
   '0': 'Hello%!',
   '1': 62224n,
   '2': 16n,
   __length__: 3,
   myString: 'Hello%!',
