The super keyword
The super keyword is used to refer to the next contract in the final inheritance chain. Let's take a look at an example to understand this:
contract sample1 { } contract sample2 { } contract sample3 is sample2 { } contract sample4 is sample2 { } contract sample5 is sample4 { function myFunc() { } } contract sample6 is sample1, sample2, sample3, sample5 { function myFunc() { //sample5.myFunc() super.myFunc(); } }
The final inheritance chain with respect to the sample6 contract is sample6, sample5, sample4, sample2, sample3, sample1. The inheritance chain starts with the most derived contracts and ends with the least derived contract.
