abi.decodeParamsV2ByABI

This method supports decode output data of function's abi. Unlike decodeParams, it supports tuple type which is already supported by solidity in new versions. It can be seen as the reverse of abi.encodeParamsV2ByABI.

Usage

tronWeb.utils.abi.decodeParamsV2ByABI(funAbi, data);

Parameters

Parameter	Description	Data Type
funAbi	The abi of a function	object contains outputs array
data	The output data	hex string

Returns

Array
