Resources and Resource Collections

This package implements ideas, which have been shamelessly + copied from Ants resource collection framework. Basically, + a resource is an abstraction of file-like entities: An actual + file, an URL, a zip entry, and so on. On the other hand, + a resource collections is a collection of resources.

+

Resource collections can be copied, moved, archived, unarchived, + and so on.

This class provides cache access to Map collections.

+ * + *

Instance of this class can be used as "proxy" for any collection + * implementing the java.util.Map interface.

+ * + *

Typically, {@link CachedMap} are used to accelerate access to + * large collections when the access to the collection is not evenly + * distributed (associative cache). The performance gain is about + * 50% for the fastest hash map collections (e.g. {@link FastMap}). + * For slower collections such as java.util.TreeMap, + * non-resizable {@link FastMap} (real-time) or database access, + * performance can be of several orders of magnitude.

+ * + *

Note: The keys used to access elements of a {@link CachedMap} do + * not need to be immutable as they are not stored in the cache + * (only keys specified by the {@link #put} method are). + * In other words, access can be performed using mutable keys as long + * as these keys can be compared for equality with the real map's keys + * (e.g. same hashCode values).

+ * + *

This implementation is not synchronized. Multiple threads accessing + * or modifying the collection must be synchronized externally.
