    Implements IEnumerable(Of KeyValuePair(Of Object, Object)),  _
    IEnumerable

public interface IReadableLocator extends IEnumerable<KeyValuePair<Object, Object>>, IEnumerable

Remarks

A locator is a dictionary of keys to values, but it keeps the values with weak references, so that locating an object does not keep it alive. If you want to keep the object alive too, you should consider using an ILifetimeContainer.

Locators have a built-in concept of hierarchy, so you can ask questions of a locator and tell it whether to return results from the current locator only, or whether to ask the parent locator when local lookups fail.
