Method Detail

getClassURI

public String getClassURI()

Description copied from class: ManagedIndividual

Get the class URI for this ManagedIndividual. All non-abstract subclasses MUST overwrite this method!

Overrides:

getClassURI in class ManagedIndividual

Returns:

The class URI.

getPropSerializationType

public int getPropSerializationType(String arg0)

Description copied from class: ManagedIndividual

Answers if the given property has to be considered when serializing this individual in a minimized way, and if not ignore-able, whether its value should be presented in its full form or can be reduced. The return value must be one of Resource.PROP_SERIALIZATION_OPTIONAL, Resource.PROP_SERIALIZATION_REDUCED, or Resource.PROP_SERIALIZATION_FULL. It can be assumed that the given property is one of those returned by FinalizedResource.getPropertyURIs(). Decision criterion should be if the value of this property is absolutely necessary when this resource is being sent to a remote node. If the subclass rates it as unlikely that the receiver side would need this info, the answer should be PROP_SERIALIZATION_OPTIONAL in favor of lower communication traffic and higher performance even at risk of a possible additional query on the receiver side for fetching this info. With the same rationale, if a property should be included in the process of serialization, it is preferable to include it in a reduced form; in this case the return value should be PROP_SERIALIZATION_REDUCED, otherwise PROP_SERIALIZATION_FULL can be returned.

Specified by:

getPropSerializationType in class ManagedIndividual

isWellFormed
