The input of decodeRaw
is expected to be an abi encoded
hex string representing a bytes[]
.
The input of decodeCalls
is expected to be an abi decoded
array of bytes.
The output is an array containing one set of candidates for each call embedded in the input.
Each set of candidates is itself an array of objects, each object describes a candidate call :
Property | Type | Description | Optional |
---|---|---|---|
signature | string | The signature of the candidate function | No |
_id | number | The id of the candidate function | No |
parameters | array | An array of Parameter objects describing the function's input | Yes |
valid | boolean | A boolean value stating the validity of this candidate. | No |
If decoding was successfull, the parameters of a valid candidate are present in the parameters
array :
Property | Description |
---|---|
type | The type of the parameter (e.g., address) |
_id | The ID of the parameter / Index in the function's signature |
value | The value of the parameter as returned by Web3 |
