Etherreum: Canceling functions of separate contracts
The Ethereum Blockchain platform is a bust at the top of Soliditty, a programming language to create intelligent contracts. Smart Contracts are self -jecution contracts with the period of business written business code lines. To achieve this, developers use functions and correspond interferences to them to annul or modify the exam behavior.
In a typical Ethereum project, multiple contracts for developing taxes. For example, the application of Decentralized Finance (DEFI) means a leading protocol, a performance farm and a statement management system. To make the application more efficiency and scalable, developers create separate constructions to interact their backs to interact.
The problems: virtual functions
What comes to canceling functions in Ethereum is a common challenge. The problems of problems in the way virtual functions are defined. A virtual function is a specified type of contract, the specified set of methods (FUCCESS) without Witout Wiitout specifies the implementation. Barley can be canceled by beer.
However, when multiplications of the SSEEM virtual function, it leads to inconsisting the integration of the project. These are Wake’s things.
The solution: separate contracts
To address this, the developer creates separate concerts to virtual function. The two are primary approaches:
- ** Use of a separate against the creation of creating a new simplified contract simply of the function of the execution function. For the exam:
charity
cited foo {
Financing is available
// Implementation
}
}
Contract bar {
using foo {going as a form of foofunction};
Overdefoo Financing () Public Returns (both) {
foolish fools ();
}
Public Financing () Public Patient
// Implementation
}
}
S
In the exam, the hiring of the bar of the bar annuls the Teopa () function of the "Foo contrasts by calling the phofunction ().
- Use of a shared storage mechanism : Another approach is to use a storage mechanism subcout, storage or storage worlds web3 to start leaving Toto. For example:
charity
cited foo {
salvages
;
foster = _data;
}
;
prognosis reforms;
}
}
Contract bar {
Footorae of Photography;
Public functionality of memory _data) public {
We are focused.
}
;
Returbs of the shape of your resort.onfodata () returned;
}
}
S
In this exam, the data instance of the ‘bar’ contractors to Ash Storage of type imagination. The “Overridefodae () function updates the directed date annulling the original origin of the graph.
* Best practices
In what the implementation fences are separated from the implementation, follow the bacicios:
- Use a consistent name for your contractions and functions.
- Clearly documented the implementation of Detics, tilting any logic or personalized reasoning Begic each cancellation.
- Testorough for dreaming the cancellation and working with expelled.
- Consider using a mechange shared storage mechanism by raising web3 storage worlds to store data.
*Conclusion
Primordial functions in Ethereum require planning and execution. By comprehensive of the challenges of virtual functions and simply separated contracts, developers can create process efficiency and intelligent intelligent intelligent contracts.
