# Class: AbiDecoder

AbiDecoder allows you to decode event logs given a set of supplied contract ABI's. It takes the contract's event
signature from the ABI and attempts to decode the logs using it.


##   Constructors



\+ **new AbiDecoder**(`abiArrays`: [AbiDefinition](#abidefinition)[][]): *[AbiDecoder](#class-abidecoder)*

*Defined in [utils/src/abi_decoder.ts:39](https://github.com/0xProject/0x-monorepo/blob/b1b9949e7/packages/utils/src/abi_decoder.ts#L39)*

Instantiate an AbiDecoder

**Parameters:**

Name | Type | Description |
------ | ------ | ------ |
`abiArrays` | [AbiDefinition](#abidefinition)[][] | An array of contract ABI's |

**Returns:** *[AbiDecoder](#class-abidecoder)*

AbiDecoder instance

## Methods

###  addABI

▸ **addABI**(`abiArray`: [AbiDefinition](#abidefinition)[], `contractName?`: undefined | string): *void*

*Defined in [utils/src/abi_decoder.ts:150](https://github.com/0xProject/0x-monorepo/blob/b1b9949e7/packages/utils/src/abi_decoder.ts#L150)*

Adds a set of ABI definitions, after which calldata and logs targeting these ABI's can be decoded.
Additional properties can be included to disambiguate similar ABI's. For example, if two functions
have the same signature but different parameter names, then their ABI definitions can be disambiguated
by specifying a contract name.

**Parameters:**

Name | Type | Description |
------ | ------ | ------ |
`abiArray` | [AbiDefinition](#abidefinition)[] | - |
`contractName?` | undefined \| string | Name of contract that encapsulates the ABI definitions (optional).                     This can be used when decoding calldata to disambiguate methods with                     the same signature but different parameter names.  |

**Returns:** *void*

___

###  decodeCalldataOrThrow

▸ **decodeCalldataOrThrow**(`calldata`: string, `contractName?`: undefined | string): *`DecodedCalldata`*

*Defined in [utils/src/abi_decoder.ts:110](https://github.com/0xProject/0x-monorepo/blob/b1b9949e7/packages/utils/src/abi_decoder.ts#L110)*

Decodes calldata for a known ABI.

**Parameters:**

Name | Type | Description |
------ | ------ | ------ |
`calldata` | string | hex-encoded calldata. |
`contractName?` | undefined \| string | used to disambiguate similar ABI's (optional). |

**Returns:** *`DecodedCalldata`*

Decoded calldata. Includes: function name and signature, along with the decoded arguments.

___

###  tryToDecodeLogOrNoop

▸ **tryToDecodeLogOrNoop**<**ArgsType**>(`log`: `LogEntry`): *`LogWithDecodedArgs<ArgsType>` | [RawLog](#rawlog)*

*Defined in [utils/src/abi_decoder.ts:55](https://github.com/0xProject/0x-monorepo/blob/b1b9949e7/packages/utils/src/abi_decoder.ts#L55)*

Attempt to decode a log given the ABI's the AbiDecoder knows about.

**Type parameters:**

▪ **ArgsType**: *`DecodedLogArgs`*

**Parameters:**

Name | Type | Description |
------ | ------ | ------ |
`log` | `LogEntry` | The log to attempt to decode |

**Returns:** *`LogWithDecodedArgs<ArgsType>` | [RawLog](#rawlog)*

The decoded log if the requisite ABI was available. Otherwise the log unaltered.

# Interface: ContractArtifact

This type defines the schema of the artifact.json file generated by Sol-compiler
schemaVersion: The version of the artifact schema
contractName: The contract name it represents
chains: Chain specific information by chain (address, id, constructor args, etc...)
compilerOutput: The Solidity compiler output generated from the specified compiler input
description (http://solidity.readthedocs.io/en/v0.4.24/using-the-compiler.html#compiler-input-and-output-json-description)
compiler: The compiler settings used
sourceCodes: The source code of the contract and all it's dependencies
sources: A mapping from source filePath to sourceMap id
sourceTreeHashHex: A unique hash generated from the contract source and that of it's dependencies.
If any of the sources change, the hash would change notifying us that a re-compilation is necessary
