com.pnfsoftware.jeb.util.serialization.AbstractTypeIdProvider

All Implemented Interfaces:

ITypeIdProvider

Direct Known Subclasses:

NativeTypeIdProvider

public abstract class AbstractTypeIdProvider
extends Object
implements ITypeIdProvider

Base class for a type-id provider used for serialization. Type-id providers can be used to de-couple the a saved object from its type name. The type-id can be saved instead, allowing type names to change without breaking the deserialization process.
