Package edu.umd.cs.findbugs.ba

Class URLClassPathRepository

java.lang.Object

edu.umd.cs.findbugs.ba.URLClassPathRepository

All Implemented Interfaces:

org.apache.bcel.util.Repository

public class URLClassPathRepository
extends java.lang.Object
implements org.apache.bcel.util.Repository

BCEL Repository implementation that uses an URLClassPath to find classes. This class has two specific improvements over BCEL's SyntheticRepository class:

1. Classpath elements may be added at any time, not just when the object is created.
2. Classpath elements can be URLs. This allows repository lookups to find classes via http URLs, jar URLs, etc.

FindBugs requires and uses both of these capabilities.
