VariableReference
public class VariableReference extends ComputedExpression implements BindingReference(Code)
Variable reference: a reference to a variable. This may be an XSLT-defined variable, a range variable defined within the XPath expression, or a variable defined in some other static context.

Field Detail
binding
Binding binding(Code)



constantValue
Value constantValue(Code)



displayName
transient String displayName(Code)



staticType
SequenceType staticType(Code)




Constructor Detail
VariableReference
public VariableReference(VariableDeclaration declaration)(Code)
Constructor
Parameters:
  declaration - the variable declaration to which this variable refers




Method Detail
computeCardinality
public int computeCardinality()(Code)
Get the static cardinality



computeSpecialProperties
public int computeSpecialProperties()(Code)
Determine the special properties of this expression StaticProperty.NON_CREATIVE (unless the variable is assignable using saxon:assign)



display
public void display(int level, NamePool pool, PrintStream out)(Code)
Diagnostic print of expression structure



equals
public boolean equals(Object other)(Code)
Test if this expression is the same as another expression. (Note, we only compare expressions that have the same static and dynamic context).



evaluateItem
public Item evaluateItem(XPathContext c) throws XPathException(Code)



evaluateVariable
public ValueRepresentation evaluateVariable(XPathContext c) throws XPathException(Code)



fixup
public void fixup(Binding binding)(Code)
Fix up this variable reference to a Binding object, which enables the value of the variable to be located at run-time.



getBinding
public Binding getBinding()(Code)
Get the object bound to the variable



getImplementationMethod
public int getImplementationMethod()(Code)
An implementation of Expression must provide at least one of the methods evaluateItem(), iterate(), or process(). This method indicates which of these methods is provided. This implementation provides both all three methods natively.



getIntrinsicDependencies
public int getIntrinsicDependencies()(Code)



getItemType
public ItemType getItemType(TypeHierarchy th)(Code)
Determine the data type of the expression, if possible the type of the variable, if this can be determined statically;otherwise Type.ITEM (meaning not known in advance)
Parameters:
  th -



hashCode
public int hashCode()(Code)
get HashCode for comparing two expressions



iterate
public SequenceIterator iterate(XPathContext c) throws XPathException(Code)
Get the value of this variable in a given context.
Parameters:
  c - the XPathContext which contains the relevant variable bindings the value of the variable, if it is defined
throws:
  XPathException - if the variable is undefined



optimize
public Expression optimize(Optimizer opt, StaticContext env, ItemType contextItemType) throws XPathException(Code)
Type-check the expression. At this stage details of the static type must be known. If the variable has a compile-time value, this is substituted for the variable reference



process
public void process(XPathContext c) throws XPathException(Code)



promote
public Expression promote(PromotionOffer offer) throws XPathException(Code)
Promote this expression if possible



setStaticType
public void setStaticType(SequenceType type, Value value, int properties)(Code)
Set static type. This is a callback from the variable declaration object. As well as supplying the static type, it may also supply a compile-time value for the variable. As well as the type information, other static properties of the value are supplied: for example, whether the value is an ordered node-set.



simplify
public Expression simplify(StaticContext env)(Code)
Simplify the expression. Does nothing.



typeCheck
public Expression typeCheck(StaticContext env, ItemType contextItemType) throws XPathException(Code)
Type-check the expression. At this stage details of the static type must be known. If the variable has a compile-time value, this is substituted for the variable reference
