XSLVariableDeclaration

public XSLVariableDeclaration()

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 interface StylesheetProcedure

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 interface VariableDeclaration

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 class StyleElement

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 class StyleElement

Throws:

XPathException

validate

public void validate()
              throws XPathException

Check that the variable is not already declared, and allocate a slot number

Overrides:

validate in class XSLGeneralVariable

Throws:

XPathException

fixupBinding

protected void fixupBinding(Binding binding)

Notify all variable references of the Binding instruction

setReferenceCount

protected void setReferenceCount(GeneralVariable var)

Overrides:

setReferenceCount in class XSLGeneralVariable
