fetch_all

public void fetch_all(ArrayList ex_ns,
                      parser par)

Will be called by the parser if he reached the EOF of the current file. The explicit stated namespaces are inside the Array List. The idea is to include everything in advance and do not allow to fetch during validation to provide a determinitic result of the validator. new since 08. Aug 2001 entered by Karsten Tolle

Specified by:

fetch_all in interface IModel

fetch

public void fetch()

Try to get all information of RDF_Properties and RDF_Classes we entered to the Model.

Specified by:

fetch in interface IModel

fetch

In the case the URI belongs to a namespace, we try to get the information about URI and enter them to our basis_model. Moved from Validator to the Model 03. Aug. 2001 by KT

Specified by:

fetch in interface IModel
