Explain an ABI.

_heading: JSON String ABI (Solidity Output JSON)
|
|
|
|
The **JSON ABI Format** is the format that is
|
|
[output from the Solidity compiler](link-solc-output).
|
|
|
|
A JSON serialized object is always a string, which represents an Array
|
|
of Objects, where each Object has various properties describing the [[Fragment]] of the ABI.
|
|
|
|
The deserialized JSON string (which is a normal JavaScript Object) may
|
|
also be passed into any function which accepts a JSON String ABI.

The Human-Readable ABI was @TODO

_heading: Output Formats @<fragments--output-formats> @SRC<abi/fragments:FormatTypes>
|
|
|
|
Each [[Fragment]] and [[ParamType]] may be output using its ``format``
|
|
method.
|
|
|
|
_property: ethers.utils.FragmentTypes.full => string
|
|
|
|
This is a full human-readable string, including all parameter names, any
|
|
optional modifiers (e.g. ``indexed``, ``public``, etc) and white-space
|
|
to aid in human readability.
|
|
|
|
_property: ethers.utils.FragmentTypes.minimal => string
|
|
|
|
This is similar to ``full``, except with no unnecessary whitespace or parameter
|
|
names. This is useful for storing a minimal string which can still fully
|
|
reconstruct the original Fragment using [Fragment . from](Fragment-from).
|
|
|
|
_property: ethers.utils.FragmentTypes.json => string
|
|
|
|
This returns a JavaScript Object which is safe to call ``JSON.stringify``
|
|
on to create a JSON string.
|
|
|
|
_property: ethers.utils.FragmentTypes.sighash => string
|
|
|
|
This is a minimal output format, which is used by Solidity when computing a
|
|
signature hash or an event topic hash.
|
|
|
|
_warning: Note
|
|
|
|
The ``sighash`` format is **insufficient** to re-create the original [[Fragment]],
|
|
since it discards modifiers such as indexed, anonymous, stateMutability, etc.
|
|
|
|
|
|
_subsection: Fragment @<Fragment> @SRC<abi/fragments:class.Fragment>
|
|
|
|
An ABI is a collection of **Fragments**, where each fragment specifies:
|
|
|
|
- An [Event](EventFragment)
|
|
- A [Function](FunctionFragment)
|
|
- A [Constructor](ConstructorFragment)
|
|
|
|
_heading: Properties
|
|
|
|
_property: fragment.name => string
|
|
|
|
This is the name of the Event or Function. This will be null for
|
|
a [[ConstructorFragment]].
|
|
|
|
_property: fragment.type => string
|
|
|
|
This is a string which indicates the type of the [[Fragment]]. This
|
|
will be one of:
|
|
|
|
- ``constructor``
|
|
- ``event``
|
|
- ``function``
|
|
|
|
_property: fragment.inputs => Array<[[ParamType]]>
|
|
|
|
This is an array of each [[ParamType]] for the input parameters to
|
|
the Constructor, Event of Function.

_property: fragment.gas => [[BigNumber]]
|
|
|
|
This is the gas limit that should be used during deployment. It may be
|
|
null.
|
|
|
|
_property: fragment.payable => boolean
|
|
|
|
This is whether the constructor may receive ether during deployment as
|
|
an endowment (i.e. msg.value != 0).
|
|
|
|
_property: fragment.stateMutability => string
|
|
|
|
This is the state mutability of the constructor. It can be any of:
|
|
|
|
- ``nonpayable``
|
|
- ``payable``

topic hash as topic0 when creating a log.

_property: fragment.constant => boolean
|
|
|
|
This is whether the function is constant (i.e. does not change state). This
|
|
is true if the state mutability is ``pure`` or ``view``.
|
|
|
|
_property: fragment.stateMutability => string
|
|
|
|
This is the state mutability of the constructor. It can be any of:

- ``nonpayable``
|

- ``payable``
|

_subsection: ParamType @<ParamType> @SRC<abi/fragments:class.ParamType>
|
|
|
|
The following examples will represent the Solidity parameter:
|
|
|
|
``string foobar``
|
|
|
|
_heading: Properties
|
|
|
|
_property: paramType.name => string @<ParamType-name>
|
|
|
|
The local parameter name. This may be null for unnamed parameters. For example,
|
|
the parameter definition ``string foobar`` would be ``foobar``.
|
|
|
|
_property: paramType.type => string @<ParamType-type>
|
|
|
|
The full type of the parameter, including tuple and array symbols. This may be null
|
|
for unnamed parameters. For the above example, this would be ``foobar``.
|
|
|
|
_property: paramType.baseType => string @<ParamType-baseType>
|
|
|
|
The base type of the parameter. For primitive types (e.g. ``address``, ``uint256``, etc)
|
|
this is equal to [type](ParamType-type). For arrays, it will be the string ``array`` and for
|
|
a tuple, it will be the string ``tuple``.
|
|
|
|
_property: paramType.indexed => boolean @<ParamType-indexed>
|
|
|
|
Whether the parameter has been marked as indexed. This **only** applies
|
|
to parameters which are part of an [[EventFragment]].
|
|
|
|
_property: paramType.arrayChildren => [[ParamType]] @<ParamType-arrayChildren>
|
|
|
|
The type of children of the array. This is null for any parameter
|
|
which is not an array.
|
|
|
|
_property: paramType.arrayLength => number @<ParamType-arrayLength>
|
|
|
|
The length of the array, or ``-1`` for dynamic-length arrays. This is
|
|
null for parameters which are not arrays.
|
|
|
|
_property: paramType.components => Array<[[ParamType]]> @<ParamType-components>
|
|
|
|
The components of a tuple. This is null for non-tuple parameters.
