Class SerializedCollection
java.lang.Object
com.myJava.util.collections.SerializedCollection
- All Implemented Interfaces:
- java.lang.Iterable, java.util.Collection
- Direct Known Subclasses:
- ZipEntrySerializedCollection
public abstract class SerializedCollection
- extends java.lang.Object
- implements java.util.Collection
Partial Collection
implementation which allows to store large collections.
The object contained in this collection are serialized and written into a buffer file (which is automatically destroyed
when the VM stops).
All add elements must implement the Serialized
interface.
Note that the add
and addAll
methods always return true and don't check wether the
added element is already contained in the collection.
This class relies on ObjectOut/Inputstreams, but only uses primitive types serializations features to avoid using instance pooling
implemented by these classes when "read/writeObject" is called (which results in a growing HashTable)
