Constructor Detail

HttpIdentifierTranslator

public HttpIdentifierTranslator(javax.jcr.Session session,
                        Class<?> relativeTo,
                        javax.ws.rs.core.UriInfo uris)

Build HTTP graph subjects relative to the given JAX-RS resource, using the UriInfo provided. The session may provide additional information (e.g. workspaces) that need to be taken into account.

Parameters:

session -

relativeTo -

uris -

HttpIdentifierTranslator

public HttpIdentifierTranslator(javax.jcr.Session session,
                        Class<?> relativeTo,
                        javax.ws.rs.core.UriInfo uris,
                        boolean canonical)

Build HTTP graph subjects relative to the given JAX-RS resource, using the UriInfo provided. The session may provide additional information (e.g. workspaces) that need to be taken into account.

Parameters:

session -

relativeTo -

uris -

canonical - generate canonical URIs for resources

Method Detail

getCanonical

public HttpIdentifierTranslator getCanonical(boolean canonical)

Get the canonical IdentifierTranslator (e.g. one that ignores transactions and other transient states)

Parameters:

canonical -

Returns:

the canonical IdentifierTranslator

isCanonical

public boolean isCanonical()

Is the current IdentifierTranslator canonical?

Returns:

true if the current IdentifierTranslator is canonical

getSubject

public com.hp.hpl.jena.rdf.model.Resource getSubject(String absPath)
                                              throws javax.jcr.RepositoryException

Throws:

javax.jcr.RepositoryException

getContext

public com.hp.hpl.jena.rdf.model.Resource getContext()

getPathFromSubject

public String getPathFromSubject(com.hp.hpl.jena.rdf.model.Resource subject)
                          throws javax.jcr.RepositoryException

Throws:

javax.jcr.RepositoryException

getPathFromGraphSubject

protected String getPathFromGraphSubject(@NotNull
                             String subjectUri)
                                  throws javax.jcr.RepositoryException

Gets a path from the graph subject's URI. This method does the heavy lifting for getNodeFromGraphSubject and getPathFromGraphSubject in a way that's tied to a more generic URI rather than a rdf Resource.

Throws:

javax.jcr.RepositoryException

isFedoraGraphSubject

public boolean isFedoraGraphSubject(com.hp.hpl.jena.rdf.model.Resource subject)

doRdfForward

protected com.hp.hpl.jena.rdf.model.Resource doRdfForward(String inputId)

Overrides:

doRdfForward in class org.fcrepo.kernel.identifiers.ExternalIdentifierConverter

doRdfBackward

protected String doRdfBackward(com.hp.hpl.jena.rdf.model.Resource subject)

Overrides:

doRdfBackward in class org.fcrepo.kernel.identifiers.ExternalIdentifierConverter

resetTranslationChain

protected void resetTranslationChain()

getBaseUri

public String getBaseUri()
