The main advantage of events is that they are stored in a special way on the blockchain so that it is very easy to search for them. -What are the different function visibilities? -============================================= - -The visibility specifiers do not only change the visibility but also -the way functions can be called. In general, functions in the -same contract can also be called internally (which is cheaper -and allows for memory types to be passed by reference). This -is done if you just use ``f(1,2)``. If you use ``this.f(1,2)`` -or ``otherContract.f(1,2)``, the function is called externally. - -Internal function calls have the advantage that you can use -all Solidity types as parameters, but you have to stick to the -simpler ABI types for external calls. - -* ``external``: all, only externally - -* ``public``: all (this is the default), externally and internally - -* ``internal``: only this contract and contracts deriving from it, only internally - -* ``private``: only this contract, only internally - - Do contract constructors have to be publicly visible? ===================================================== |
