compileSingletonPackage
public static PreparedStylesheet compileSingletonPackage(Configuration config, CompilerInfo compilerInfo, javax.xml.transform.Source source) throws XPathException
Static factory method: Compile an XSLT stylesheet consisting of a single package- Parameters:
config- the Saxon ConfigurationcompilerInfo- the compilation optionssource- 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

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.
