The base URI for absolutizing relative URIs.

Constructor Detail

ExternalReferenceResolverImpl

public ExternalReferenceResolverImpl(URI base)

Creates a new resolver which uses the specified URI as basis for absolutizing relative URIs.

Parameters:

base - The base URI for absolutizing relative URIs.

Method Detail

resolve

public java.io.InputStream resolve(URI uri)
                            throws ExternalReferenceResolverException

Currently only the case of a specified location (URL) is covered by this method: It relies on method URL.openStream(). The case of a specified name (URN) is not covered and leads to an exception. This implementation does not evaluate the eventually existing reference part of the specified URI!

Specified by:

resolve in interface ExternalReferenceResolverInterface

Parameters:

uri - The specified URI to be resolved. Must not be null.

Returns:

an InputStream representing the resolved URL.

Throws:

ExternalReferenceResolverException - if the specified URI is relative and cannot be absolutized, or if the specified URI cannot be resolved with the mechanism explained above.

setBaseURI

public void setBaseURI(URI baseURI)

Sets the base URI used for absolutizing relative URIs.

Specified by:

setBaseURI in interface ExternalReferenceResolverInterface

Parameters:

baseURI - The base URI. Must not be null.
