public class NttObjectReference

extends PcteObjectReference

A class representing NTT object references.
In addition to PCTE object references they contain additional information about the query specific schema (e.g. virtual links). All operations are able to cope with the inaccessibility of parts of the database in a senseful way. Further information about the NTT database query language is available at NTT's Homepage

Method Detail

getAttribute

public PcteAttributeValue getAttribute(java.lang.String attribute)
                                throws NttException,
                                       PcteException

NTT's API operation to get an object attribute.
The attribute may be virtual and is computed in the query specific schema.

Parameters:

attribute - the name of the desired attribute

Returns:

the desired attribute value or null, if the result value is unknown (i.e. cannot be computed)

PcteObjectReference.Pcte_object_get_attribute(java.lang.String)

getDestinationObjects

public NttVagueObjSet getDestinationObjects(java.lang.String link)
                                     throws NttException,
                                            PcteException

NTT's API operation for navigation.
The link (or link pattern) may be virtual and the result objects are computed in the query specific schema.

Parameters:

link - the link name (pattern) to follow

Returns:

the NttVagueObjSet containing the reached objects
