Examples of com.persistit.encoding.CollectionValueCoder

com.persistit.encoding.CollectionValueCoder
Implements ValueCoder, ValueRenderer and ValueDisplayer for selected classes in the Java Collections API. By default an instance of this coder is registered for each of the following concrete classes:
- java.util.ArrayList
- java.util.LinkedList
- java.util.Stack
- java.util.Vector
- java.util.Properties
- java.util.HashMap
- java.util.HashSet
- java.util.Hashtable
- java.util.TreeMap
- java.util.TreeSet
- java.util.LinkedHashMap (Java 1.4+)
- java.util.LinkedHashSet (Java 1.4+)
The stored data consist only of items accessible through the Collection or Map interfaces. For example, implementation details such as the current loadFactor for a HashMap are not stored. For any Collection (including List and Set), the stored format is simply a list of all the values in the order returned by an Iterator. For a Map the stored format is simply a key/value pair for each entry in the order returned by the Iterator returned by the entrySet() method of the Map.

Because customer-written Collection and Map implementations may contain additional internal state that may also need to be stored when they are serialized, this coder is registered only for specific implementations provided by the JRE. You may register and use this ValueCoder for any custom Collection or Map that does not need to serialize additional data.

Note that for ArrayList, Vector, Stack , and other List implementations that do not extend AbstractSequentialList, the serialization logic uses the get(index) method of List to acquire each member rather than constructing an Iterator. Subclasses of AbstractSequentialList are serialized by using an Iterator because access by index may be inefficient.
