io microsphere classloading AbstractURLClassPathHandle

AbstractURLClassPathHandle

Type: Class | Module: microsphere-java-core | Package: io.microsphere.classloading | Since: 1.0.0

Source: microsphere-java-core/src/main/java/io/microsphere/classloading/AbstractURLClassPathHandle.java

Overview

Abstract implementation of URLClassPathHandle that provides a base for handling URL Class-Path entries.

This class offers reflective access to internal structures like the ucp, urls, and loaders fields used by the JVM's class loading mechanism. It is primarily designed for advanced use cases where fine-grained control over class loader URLs is required, such as dynamic removal or modification of URLs from a class loader.

Key Features:

• Supports reflective manipulation of internal JVM class loading structures.
• Provides abstraction over different versions of JVM internals (e.g., classic vs modern JDK).
• Implements the Prioritized interface to allow prioritization among multiple handlers.

Example Usage

`public class ClassicURLClassPathHandle extends AbstractURLClassPathHandle {

    public ClassicURLClassPathHandle() {
        // Default constructor
    `

    protected String getURLClassPathClassName() {
        return "sun.misc.URLClassPath";
    }

    protected String getUrlsFieldName() {
        return "urls"; // Classic field name
    }
}
}

Declaration

public abstract class AbstractURLClassPathHandle implements URLClassPathHandle, Prioritized
