Parameters:

baseS -

JenaURIException - If resulting base would not be legal, absolute IRI

Method Detail

resolveFileURL

public static String resolveFileURL(String filename)
                             throws com.hp.hpl.jena.iri.IRIException

resolve

public static String resolve(String relStr,
                             String baseStr)
                      throws JenaURIException

Parameters:

relStr -

baseStr - Can be null if relStr is absolute

Returns:

String An absolute URI

Throws:

JenaURIException - If result would not be legal, absolute IRI

getBaseIRI

public String getBaseIRI()

The base of this IRIResolver.

Returns:

The string representation of the base.

resolve

public String resolve(String relURI)

Resolve the relative URI against the base of this IRIResolver.

Parameters:

relURI -

Returns:

the resolved IRI

Throws:

JenaURIException - If resulting URI would not be legal, absolute IRI

suppressExceptions

public static void suppressExceptions()

To allow Eyeball to bypass IRI checking (because it's doing its own)

resolveGlobal

public static String resolveGlobal(String str)

Resolve the relative URI str against the current working directory.

Parameters:

str -

Returns:

The resolved URI as a string.

chooseBaseURI

public static String chooseBaseURI()

Choose a base URI based on the current directory

Returns:

String Absolute URI

chooseBaseURI

public static String chooseBaseURI(String baseURI)

Choose a baseURI based on a suggestion

Returns:

String URI (if relative, relative to current working directory).
