<p>Public call functions are an essential component of many software architectures and designs. </p>



<p>Here is a deeper look at what public calls are, why they are used, and their importance in software development.</p>



<h2 class="wp-block-heading tablecontent">What are Public Call Functions?</h2>



<p>A public call function in software is a function or method that is declared with the <strong><a href="https://www.freecodecamp.org/news/java-access-modifiers-explained/#:~:text=Public%20Access%20Modifier&amp;text=A%20class%2C%20method%20or%20variable,other%20class%20at%20any%20time." data-type="URL" data-id="https://www.freecodecamp.org/news/java-access-modifiers-explained/#:~:text=Public%20Access%20Modifier&amp;text=A%20class%2C%20method%20or%20variable,other%20class%20at%20any%20time." target="_blank" rel="noreferrer noopener">public access modifier</a></strong>. </p>



<p>This means it can be called and accessed by code external to the class or module where the function is defined.</p>



<p>Some key properties of public functions:</p>



<ul>
<li>They are part of the public interface or API of a class/module that other code can rely on.</li>



<li>They allow for <strong><a href="https://www.simplilearn.com/tutorials/java-tutorial/java-encapsulation#:~:text=Encapsulation%20in%20Java%20is%20the,the%20class%20can%20access%20them." data-type="URL" data-id="https://www.simplilearn.com/tutorials/java-tutorial/java-encapsulation#:~:text=Encapsulation%20in%20Java%20is%20the,the%20class%20can%20access%20them." target="_blank" rel="noreferrer noopener">encapsulation</a></strong> - implementation details are hidden and external code only interacts through the public interface.</li>



<li>They enable modular and reusable code architecture.</li>



<li>They should be documented properly to allow external use.</li>



<li>They can be invoked directly using the class and function name syntax.</li>
</ul>



<p>Public functions contrasts with private functions which can only be called within the same class.</p>



<h2 class="wp-block-heading tablecontent">Why Use Public Functions?</h2>



<p>There are several important reasons public functions are used in software design:</p>



<h5 class="wp-block-heading"><strong>Enable Modular Architecture</strong></h5>



<p>Public functions allow classes to expose an interface that can be relied upon by other parts of the codebase. </p>



<p>This encourages modular architecture where each class encapsulates specific functionality and exposes a public API.</p>



<h5 class="wp-block-heading"><strong>Code Reuse</strong></h5>



<p>With public functions, code in one class can leverage functionality defined in another class without having to know its implementations. </p>



<p>This allows reuse of code across the codebase.</p>



<h5 class="wp-block-heading"><strong>Abstraction</strong></h5>



<p>The implementation details of a class can be hidden behind its public functions. </p>



<p>This provides abstraction that helps manage complexity.</p>



<h5 class="wp-block-heading"><strong>Standardized Interface</strong></h5>



<p>Public functions enable a standardized interface for interacting with a class/module across the codebase. </p>



<p>External code simply relies on the public interface rather than internal implementation.</p>



<h2 class="wp-block-heading tablecontent">Facilitate Testing</h2>



<p>Public functions enable better unit testing of classes in isolation using mock objects and stubs to simulate behaviour. </p>



<p>The interface remains standardized while internal implementation can be tested.</p>



<h5 class="wp-block-heading"><strong>Better Collaboration</strong></h5>



<p>Public functions allow better division of responsibility and collaboration between classes. </p>



<p>Rather than monolithic classes, responsibilities can be divided across classes that provide and consume public functions.</p>



<h5 class="wp-block-heading"><strong>Maintainable Code</strong></h5>



<p>With changes isolated through public functions, code is easier to maintain over time. </p>



<p>As long as the public interface remains the same, internal implementation can be changed without affecting external code.</p>



<h2 class="wp-block-heading tablecontent">Best Practices For Public Functions</h2>



<p>Properly leveraging public functions requires some best practices:</p>



<ul>
<li>Provide clear and thorough documentation on usage of the public functions.</li>



<li>Keep public interfaces and functions simple, concise and easy to use.</li>



<li>Try to maintain backwards compatibility of public APIs over time.</li>



<li>Avoid exposing unnecessary internal details through public functions.</li>



<li>Use access modifiers properly to encapsulate private state and utility functions.</li>
</ul>

<p>In order to facilitate this process, users of the protocol are incentivized to liquidate vaults via a public call function.</p>



<h2 class="wp-block-heading tablecontent">Conclusion</h2>



<p>Public call functions enable modular and reusable code by exposing a class&#x27;s capabilities through an interface abstracted from its internal details. </p>



<p>They facilitate better code organization, testing, collaboration and long-term maintenance. Following best practices for public APIs allows leveraging encapsulation and abstraction effectively. </p>



<p>In object oriented programming, public functions are a critical tool for managing complexity in large and complex software systems.</p>
