                                                  throws XPathException
        Static factory method: Compile an XSLT stylesheet consisting of a single package
        Parameters:
        config - the Saxon Configuration
        compilerInfo - the compilation options
        source - the source of the root stylesheet module in the package to be compiled. This may contain an xsl:package element at its root, or it may be a conventional xsl:stylesheet or xsl:transform, or a "simplified stylesheet" rooted at a literal result element
        Returns:
        the PreparedStylesheet representing the result of the compilation
        Throws:
        XPathException - if any errors occur. The errors will have been reported to the ErrorListener contained in the CompilerInfo.

      • setUsingPackages

        public void setUsingPackages​(java.util.List<VersionedPackageName> users)
        Supply the name/version of the package that invoked this compilation by virtue of an xsl:use-package declaration, together with the users of that package, recursively. The package is not allowed to use the packages in this list, because that would create a cycle of dependencies
        Parameters:
        users - the packages that directly or indirectly use this package.

      • setPackageData

        public void setPackageData​(PackageData pack)

      • registerPackageDependency

        public void registerPackageDependency​(UsePack use)
        Method called internally while compiling a package to register that an xsl:use-package declaration has been encountered.
        Parameters:
        use - details of the package dependency (name and version of the dependee package)

      • satisfyPackageDependencies

        public void satisfyPackageDependencies​(XSLPackage thisPackage)
                                throws XPathException
        After the first phase of processing, we have gathered information about the xsl:use-package elements in the stylesheet. We now ensure that these dependencies are satisfied and are bound to actual loaded packages, invoking the compiler recursively to load the package if necessary. If there are cyclic references, these must be detected.
        Parameters:
        thisPackage - the package being checked
        Throws:
        XPathException - if errors are found

      • compilePackage

        Compile a stylesheet package
        Parameters:
        source - the XML document containing the top-level stylesheet module in the package, which may be an xsl:package element, an xsl:stylesheet or xsl:transform element, or a "simplified stylesheet" rooted at a literal result element
        Returns:
        the StylesheetPackage representing the result of the compilation

Non-static parameters may also be provided using this method if their values will not vary from one transformation to another. No error occurs at this stage if the parameter is unknown, or if the value is incorrect for the parameter. Setting a value for a parameter overwrites any previous value set for the same parameter.

        Parameters:
        fallbackToNonStreaming - true if a construct has been found that is declared streamable but not actually streamable, if fallback processing was requested.
