public interface PackagePersistenceMaster

Title: Description: A PackagePersistenceMaster instance provides descriptive information on Entity instances to be persisted. Thus, each actor using perstistence needs to implement PackagePersistenceMaster for the Entity instances it persists.

Method Detail

getClasstypes

public java.lang.String[] getClasstypes()

Gets the classtypes this PackagePersistenceMaster instance is responsible for. Type-distinction of Entity instances is made by classtype, an abstraction of the actual java class.

The classtype is linked to a ClassDescriptor which describes how an Entity is persistently read and written. The classtype may be linked as n:m to a specific java class; this means that instances of different classes may be treated uniquely for persistence as well as instances of the same class may be treated differently for persistence.

Returns:

The classtypes value

getClassDescriptor

public ClassDescriptor getClassDescriptor(java.lang.String classtype)

Returns the descriptive information for a certain classtype

Parameters:

classtype - Description of the Parameter

Returns:

The persistableClass value
