Module: calldata/evm
Functions
getNestedCalldata
▸ getNestedCalldata(def, calldata): any[]
Pull out nested calldata which may correspond to nested ABI definitions.
This is relevant for e.g. multicall patterns.
A def may be nested if the underlying type is bytes or bytes[] and
the calldata parm is of size (4 + 32*n).
Parameters
| Name | Type | Description |
|---|---|---|
def | any | calldata decoder data for a def |
calldata | any | Buffer containing full calldata payload |
Returns
any[]
- Array of calldata params, or null values. If the return item has data (0x-prefixed hex string), it should be checked as a possible nested def
Defined in
parseCanonicalName
▸ parseCanonicalName(sig, name): any[]
Convert a canonical name into an ABI definition that can be included with calldata to a general "2", "2.1", "3")
Parameters
| Name | Type | Description |
|---|---|---|
sig | string | a 0x-prefixed hex string containing 4 bytes of info |
name | string | canonical name of the function |
Returns
any[]
Buffer containing RLP-serialized array of calldata info to pass to signing request
Defined in
parseSolidityJSONABI
▸ parseSolidityJSONABI(sig, abi): Object
Look through an ABI definition to see if there is a function that matches the signature provided.
Parameters
| Name | Type | Description |
|---|---|---|
sig | string | a 0x-prefixed hex string containing 4 bytes of info |
abi | any[] | a Solidity JSON ABI structure (external link) |
Returns
Object
Buffer containing RLP-serialized array of calldata info to pass to signing request
| Name | Type |
|---|---|
def | EVMDef |
Defined in
replaceNestedDefs
▸ replaceNestedDefs(def, nestedDefs): any
If applicable, update decoder data to represent nested
definitions, which are used in e.g. multicall patterns.
This will update def in place and return it with any
additional info necessary.
Parameters
| Name | Type | Description |
|---|---|---|
def | any | Decoder data for a specific calldata function (def) |
nestedDefs | any | Array containing a possible set of nested defs which must be added to def |
Returns
any
- Possibly modified version of
def
