io.microsphere.reflect.ClassDefinition

All Implemented Interfaces:

java.io.Serializable

public class ClassDefinition
extends ReflectiveDefinition

A concrete implementation of ReflectiveDefinition representing the definition of a Java class.

This class provides reflection-based access to information about a class, including its name, version since introduction, deprecation status, and whether it is currently present in the runtime environment.

Example Usage

 // Create a ClassDefinition for a class introduced in version "1.0.0"
 ClassDefinition definition = new ClassDefinition("1.0.0", "java.util.ArrayList");

 // Check if the class is available in the current runtime
 boolean isPresent = definition.isPresent(); // returns true if 'ArrayList' is found

 // Get the version since the class was introduced
 Version sinceVersion = definition.getSince(); // e.g., version "1.0.0"

 // Get the resolved Class object (may be null if not found)
 Class<?> resolvedClass = definition.getResolvedClass();
 

If the class is marked as deprecated, you can retrieve the deprecation details using ReflectiveDefinition.getDeprecation().

Since:

1.0.0
