Method Detail

resolve

public Source resolve(String href,
             String base)
               throws TransformerException

file: uri resolution is delegated to the system URI resolver. lux: and other uris are all resolved by #getDocument(String). The lux: prefix is optional, e.g: the uris "lux:/hello.xml" and "/hello.xml" are equivalent.

Specified by:

resolve in interface URIResolver

Throws:

TransformerException - if the document is not found

getDocument

public net.sf.saxon.s9api.XdmNode getDocument(String uri)
                                       throws TransformerException

Evaluator provides this method as an implementation of URIResolver so as to resolve uris in service of fn:doc(). file: uri resolution is delegated to the default resolver by returning null. lux: and other uris are all resolved using the provided searcher. The lux: prefix is optional, e.g: the uris "lux:/hello.xml" and "/hello.xml" are equivalent. Documents read from the index are numbered according to their Lucene docIDs, and retrieved using the CachingDocReader.

Parameters:

uri - the uri of the document to retrieve

Returns:

the document node

Throws:

IllegalStateException - if the resolver wasn't configured properly (has no searcher)

TransformerException - or there was an IOException thrown by Lucene.

NotFoundException - if the document is not found in the index

getSearcher

public LuxSearcher getSearcher()

getDocReader

public CachingDocReader getDocReader()
