Package net.sf.saxon.style

Class PrincipalStylesheetModule

java.lang.Object
net.sf.saxon.style.StylesheetModule
net.sf.saxon.style.PrincipalStylesheetModule
All Implemented Interfaces:
GlobalVariableManager
Direct Known Subclasses:
PrincipalStylesheetModuleEE
public class PrincipalStylesheetModule extends StylesheetModule implements GlobalVariableManager
Represents both the stylesheet module at the root of the import tree, that is, the module that includes or imports all the others, and also the XSLT package that has this stylesheet module as its root.

This version of the StylesheetPackage class represents a trivial package that is constructed by the system to wrap an ordinary (non-package) stylesheet, as available in XSLT 2.0. A subclass is used for "real" packages, currently available only in Saxon-EE.

      Get an existing global variable whose initializer is a given expression, if there is one. Note that this depends on the logic for detecting equivalence of expressions, which is necessarily approximate. Expressions with dependencies on the static context should never be considered equivalent. If no equivalent global variable is found, return null.

      select - the expression to which the variable is bound
      Returns:
