@ -410,15 +410,19 @@ A function description is a JSON object with the fields:
* ``components``: used for tuple types (more below).
- ``outputs``: an array of objects similar to ``inputs``, can be omitted if function doesn't return anything;
- ``payable``: ``true`` if function accepts ether, defaults to ``false``;
- ``stateMutability``: a string with one of the following values: ``pure`` (:ref:`specified to not read blockchain state <pure-functions>`), ``view`` (:ref:`specified to not modify the blockchain state <view-functions>`), ``nonpayable`` and ``payable`` (same as ``payable`` above).
- ``constant``: ``true`` if function is either ``pure`` or ``view``
- ``stateMutability``: a string with one of the following values: ``pure`` (:ref:`specified to not read blockchain state <pure-functions>`), ``view`` (:ref:`specified to not modify the blockchain state <view-functions>`), ``nonpayable`` (function does not accept ether) and ``payable`` (function accepts ether);
- ``payable``: ``true`` if function accepts ether, ``false`` otherwise;
- ``constant``: ``true`` if function is either ``pure`` or ``view``, ``false`` otherwise.
``type`` can be omitted, defaulting to ``"function"``.
``type`` can be omitted, defaulting to ``"function"``, likewise ``payable`` and ``constant`` can be omitted, both defaulting to ``false``.
Constructor and fallback function never have ``name`` or ``outputs``. Fallback function doesn't have ``inputs`` either.
Sending non-zero ether to non-payable function will throw. Don't do it.
.. warning::
The fields ``constant`` and ``payable`` are deprecated and will be removed in the future. Instead, the ``stateMutability`` field can be used to determine the same properties.
.. note::
Sending non-zero ether to non-payable function will revert the transaction.
An event description is a JSON object with fairly similar fields:
