      • uri

        public java.lang.String uri
        The URI to be dereferenced. If the request was for a relative URI reference, this will be the absolute URI after resolving against the base URI if known; if no base URI is known, it will be the URI as requested.

      • baseUri

        public java.lang.String baseUri
        The base URI that was used to resolve any relative URI, if known.

      • relativeUri

        public java.lang.String relativeUri
        The relative URI that was actually requested, where applicable.

      • publicId

        public java.lang.String publicId
        The public ID of the requested resource, where applicable

      • entityName

        public java.lang.String entityName
        The name of the requested resource, used when resolving entity references

      • nature

        public java.lang.String nature
        The Nature of the resource, as defined in the RDDL specifications (based on the role attribute in XLink). Some of the allowed values are provided as constants, for example TEXT_NATURE, XSLT_NATURE, XQUERY_NATURE.

      • purpose

        public java.lang.String purpose
        The Purpose of the request, as defined in the RDDL specifications (based on the arcrole attribute in XLink).

      • uriIsNamespace

        public boolean uriIsNamespace
        This boolean flag is set to true when the URI takes the form of a namespace URI (rather than a location hint). Specifically, it is set when resolving an import module declaration in XQuery when only the module namespace is known, and when resolving an xsl:import, or an XML Schema import in XSLT or XQuery, if only the target namespace of the required schema document is known.

      • streamable

        public boolean streamable
        This boolean flag is set to true when the URI identifies a document where streamed processing is required. In this case the result must be a StreamSource or SAXSource

      • copy

        public ResourceRequest copy()
        Make a copy of a resource request (so that it can be modified without changing the original)
        Returns:
        a copy of the request

      • resolve

        public javax.xml.transform.Source resolve​(ResourceResolver... resolvers)
                                   throws XPathException
        Resolve the request by passing it to one or more resource resolvers. The resolvers are tried in turn until one of them returns a non-null result; if the final result is null, this method returns null
        Parameters:
        resolvers - the resource resolvers to be used
        Returns:
        the result from the first resolver that returns a non-null result; or null if none of them does so.
        Throws:
        XPathException
