Interface IRuntimeContainerComparator

Deprecated. support has been added to `ClasspathContainerInitializer` to handle comparison of classpath containers. Use `ClasspathContainerInitializer.getComparisonID(IPath,IJavaProject)`. When a classpath container implements this interface, this interface is used to determine equality before using the support defined in `ClasspathContainerInitializer`.

public interface IRuntimeContainerComparator

Determines if container entries are duplicates/redundant on a runtime classpath. If an `IClasspathContianer` implements this interface, the `isDuplicate` method is used to determine if containers are duplicates/redundant. Otherwise, containers with the same identifier are considered duplicates.

Since:
  2.0.1

Method Summary
`boolean` | `isDuplicate(IPath containerPath)` Deprecated. Returns whether this container is a duplicate of the conatiner identified by the given path.
