Class CollectionSchema<V>

java.lang.Object
  com.dyuproject.protostuff.CollectionSchema<V>

All Implemented Interfaces:

Schema<java.util.Collection<V>>

Direct Known Subclasses:

MessageCollectionSchema

public abstract class CollectionSchema<V>
extends java.lang.Object
implements Schema<java.util.Collection<V>>

A schema for standard jdk collections. Null values are not serialized/written. If your application relies on Object.equals(Object), it will fail when a serialized collection contains null values (The deserialized collection will not contained the null value). MapSchema on the otherhand can contain both null keys and null values and still succeeding on Object.equals(Object).
