Method Detail
-
getSlotManager
public SlotManager getSlotManager()
Get the SlotManager associated with this stylesheet construct. The SlotManager contains the information needed to manage the local stack frames used by run-time instances of the code.- Specified by:
getSlotManager
in interfaceStylesheetProcedure
- Returns:
- the associated SlotManager object
-
getSlotNumber
public int getSlotNumber()
-
setSlotNumber
public void setSlotNumber(int slot)
-
getRequiredType
public abstract SequenceType getRequiredType()
Get the static type of the variable.
-
registerReference
public void registerReference(BindingReference ref)
Method called by VariableReference to register the variable reference for subsequent fixup- Specified by:
registerReference
in interfaceVariableDeclaration
-
getReferences
public java.util.List getReferences()
Get the list of references to this variable or parameter. The items in the list are of class BindingReference.
-
isInstruction
public boolean isInstruction()
Determine whether this node is an instruction.- Overrides:
isInstruction
in classStyleElement
- Returns:
- true - it is an instruction (well, it can be, anyway)
-
getReferenceList
public java.util.List getReferenceList()
Get the list of references
-
fixupReferences
public void fixupReferences() throws XPathException
Notify all references to this variable of the data type- Overrides:
fixupReferences
in classStyleElement
- Throws:
XPathException
-
validate
public void validate() throws XPathException
Check that the variable is not already declared, and allocate a slot number- Overrides:
validate
in classXSLGeneralVariable
- Throws:
XPathException
-
fixupBinding
protected void fixupBinding(Binding binding)
Notify all variable references of the Binding instruction
-
setReferenceCount
protected void setReferenceCount(GeneralVariable var)
Set the number of references to this variable. This code is invoked only for a global variable, and only if there is at least one reference.- Overrides:
setReferenceCount
in classXSLGeneralVariable
- Parameters:
var
