fuzzy_dl_owl2.fuzzydl.concept.interface.has_value_interface

An abstract interface is provided for managing concepts that require both a specific role and an associated generic value.

Description

Building upon the foundation of role management, this abstract class introduces the capability to associate an arbitrary value with a specific role. It encapsulates this data through a private attribute that is accessible and modifiable via public properties, ensuring that subclasses can represent or manipulate specific data within a defined context. The initialization process delegates role handling to the parent class while simultaneously storing the provided value, thereby combining role and value attributes into a cohesive interface. Although the documentation suggests isolation of state, the current implementation of the value setter assigns the object by reference rather than creating a deep copy, meaning that modifications to mutable objects will affect the internal state directly.

Classes

HasValueInterface

This abstract base class extends role management capabilities by introducing a mechanism to handle a generic value alongside a role. It provides concrete implementations for initializing and accessing the value, with the setter specifically utilizing a deep copy operation to ensure that the internal state remains isolated from external modifications. By combining role and value attributes, it offers a consistent interface for objects that need to represent or manipulate specific data within a defined context.

This abstract base class extends role management capabilities by introducing a mechanism to handle a generic value alongside a role. It provides concrete implementations for initializing and accessing the value, with the setter specifically utilizing a deep copy operation to ensure that the internal state remains isolated from external modifications. By combining role and value attributes, it offers a consistent interface for objects that need to represent or manipulate specific data within a defined context.

Parameters:

_value (Any) – Internal storage for the value represented by the class, managed via the public property and stored as a deep copy to prevent external mutation.

_value: Any

property value: Any

Retrieves the current value stored in the instance. This getter provides access to the internal _value attribute without creating a copy, meaning that modifications to the returned object will affect the internal state if the object is mutable.

Returns:

The value currently stored in the instance.

Return type:

Any
