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.

getSlotManager

getEquivalentVariable

public GlobalVariable getEquivalentVariable(Expression select)

Description copied from interface: GlobalVariableManager

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. An implementation can always return null if it wants to avoid a lengthy search.

Specified by:

getEquivalentVariable in interface GlobalVariableManager

Returns:

an existing global variable with the same select expression, if one can be found; otherwise null.

addGlobalVariable

public void addGlobalVariable(GlobalVariable variable)

Description copied from interface: GlobalVariableManager

Add a global variable to the collection

Specified by:

addGlobalVariable in interface GlobalVariableManager

Parameters:

variable - the variable to be added

addGlobalVariable

public void addGlobalVariable(GlobalVariable variable,
                              Visibility visibility)
