Annotation Type PortableProperty

@Target(value={FIELD,METHOD})
 @Retention(value=RUNTIME)
public @interface PortableProperty

A PortableProperty marks a member variable or method accessor as a POF serialized attribute. Whilst the value() and codec() can be explicitly specified they can be determined by classes that use this annotation. Hence these attributes serve as hints to the underlying parser.

codec

public abstract Class<?> codec

A Codec to use to override the default behavior in serializing and deserializing a property.

The Class specified must have a no-arg constructor and must implement one of:

1. Codec - the specified Codec implementation will be instantiated and returned.
2. Collection - the specified class should implement the Collection interface. A Codec implementation that supports the Collection type will be used.
3. Map - the specified class should implement the Map interface. A Codec implementation that supports the Map type will be used.
4. LongArray - the specified class should implement the LongArray interface. A Codec implementation that supports the LongArray type will be used.
5. T[] - the provided class should be an array and the component type of the array should have a no-arg constructor. A Codec implementation that supports arrays will be used.

For example, to override the default serialization/deserialization to use a LinkedList implementation could be as trivial as:

Returns:

a Class representing the codec to use for this property, or a an implementation of a well known type (Collection, Map, LongArray, or an array)
