Class ResourceCollection<Resource>

java.lang.Object

edu.umd.cs.findbugs.ResourceCollection<Resource>

public class ResourceCollection<Resource>
extends java.lang.Object

A ResourceCollection defines all of the resources created and used in a particular method. It serves two related purposes:

1. Define all of the resources which exist in the method, and
2. Record where resources created in the method are created

This distinction is important because some resources which exist in the method aren't created in the method: for example, resources passed in as parameters.
