Create a contract that can be killed and return funds
|
|
||||||
=====================================================
|
|
||||||
|
|
||||||
First, a word of warning: Killing contracts sounds like a good idea, because "cleaning up"
|
|
||||||
is always good, but as seen above, it does not really clean up. Furthermore,
|
|
||||||
if Ether is sent to removed contracts, the Ether will be forever lost.
|
|
||||||
|
|
||||||
If you want to deactivate your contracts, it is preferable to **disable** them by changing some
|
|
||||||
internal state which causes all functions to throw. This will make it impossible
|
|
||||||
to use the contract and ether sent to the contract will be returned automatically.
|
|
||||||
|
|
||||||
Now to answering the question: Inside a constructor, ``msg.sender`` is the
|
|
||||||
creator. Save it. Then ``selfdestruct(creator);`` to kill and return funds.
|
|
||||||
|
|
||||||
`example <https://github.com/fivedogit/solidity-baby-steps/blob/master/contracts/05_greeter.sol>`_
|
|
||||||
|
|
||||||
Note that if you ``import "mortal"`` at the top of your contracts and declare
|
|
||||||
``contract SomeContract is mortal { ...`` and compile with a compiler that already
|
|
||||||
has it (which includes `Remix <https://remix.ethereum.org/>`_), then
|
|
||||||
``kill()`` is taken care of for you. Once a contract is "mortal", then you can
|
|
||||||
``contractname.kill.sendTransaction({from:eth.coinbase})``, just the same as my
|
|
||||||
examples.

If I return an ``enum``, I only get integer values in web3.js. How to get the named values?
