Codebase Refactoring for Improved Readability and Maintainability

[risvarrt]

This pull request introduces a series of six refactoring changes aimed at enhancing the readability, maintainability, and overall design of the codebase. Each refactoring is summarized below:

Introduce Explaining Variables

Refactored the equalTimeValue method within the Equality class by adding two explaining variables: equalTimeStamp and equalTolerance.

Extract Method

Simplified the getJsonDatatypeFromDatatypeIri method in the DataTypeIdImpl class by extracting logic for the default case to a new method, enhancing readability.

Decompose Conditional - WbEditingAction

Improved the performAPIAction method within the WbEditingAction class by decomposing conditional logic into smaller methods (validateIfnewEntity, validateEditEntityDataUsingId, validateEditEntityData), focusing on core logic.

Extract Class - DataTypeJsonUtils

Introduced the DataTypeJsonUtils class to separate JSON conversion logic from execution logic, adhering to the Single Responsibility Principle.

Move Method - getReferenceUri

Improved design by moving getReferenceUri logic from Vocabulary to ReferenceRdfConverters, aligning responsibilities with the classes most directly involved.

Pull up Variable - constructTermMap and toTerm

Centralized the constructTermMap and toTerm methods by pulling them up into the StatementDocumentImpl class. This change eliminates duplication and simplifies constructTermMap across various inherited classes.

Each refactoring change preserves the existing functionality and interface contracts, ensuring backward compatibility and uninterrupted operation. The focus has been on internal improvements that enhance our code's structure without altering its behavior from an external viewpoint.

Your feedback and suggestions on these refactorings are welcome.

Hi @risvarrt,
I am curious what brought you to work on this. Is it for an assignment at university perhaps?
Or do you need such refactorings yourself to enable further improvements to WDTK? Which ones?
I had a quick look at the changes and I don't understand why they'd be improvements, but perhaps I can relate better to your needs once you give me a bit more background on what brought you to submitting this.
Thank you!

[risvarrt]

Yes, It is a part of my assignment. Also, I wanted to apply my learnings on refactoring and code smells on this repository
Let me know if any other changes are needed here.

Ok. Would you be able to share the detailed instructions you have been given for this assignment?
