   net.sf.saxon.expr.ComputedExpression
      net.sf.saxon.sort.SortExpression

SortExpression
public class SortExpression extends ComputedExpression (Code)
Expression equivalent to the imaginary syntax expr sortby (sort-key)+



Constructor Summary
public  SortExpression(Expression select, SortKeyDefinition[] sortKeys)
    

Method Summary
public  intcomputeCardinality()
    
public  intcomputeSpecialProperties()
     Get the static properties of this expression (other than its type).
public  voiddisplay(int level, NamePool pool, PrintStream out)
    
public  ItemTypegetItemType(TypeHierarchy th)
    
public  booleanisSortKey(Expression child)
    
public  SequenceIteratoriterate(XPathContext context)
    
public  IteratoriterateSubExpressions()
     Get the immediate sub-expressions of this expression.
public  Expressionoptimize(Optimizer opt, StaticContext env, ItemType contextItemType)
     Perform optimisation of an expression and its subexpressions.

This method is called after all references to functions and variables have been resolved to the declaration of the function or variable, and after all type checking has been done.


Parameters:
  opt - the optimizer in use.
public  Expressionpromote(PromotionOffer offer)
     Offer promotion for this subexpression.
public  Expressionsimplify(StaticContext env)
    
public  ExpressiontypeCheck(StaticContext env, ItemType contextItemType)
    


Constructor Detail
SortExpression
public SortExpression(Expression select, SortKeyDefinition[] sortKeys)(Code)




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



computeSpecialProperties
public int computeSpecialProperties()(Code)
Get the static properties of this expression (other than its type). The result is bit-significant. These properties are used for optimizations. In general, if property bit is set, it is true, but if it is unset, the value is unknown.



display
public void display(int level, NamePool pool, PrintStream out)(Code)



getItemType
public ItemType getItemType(TypeHierarchy th)(Code)
Determine the data type of the items returned by the expression, if possible a value such as Type.STRING, Type.BOOLEAN, Type.NUMBER, Type.NODE,or Type.ITEM (meaning not known in advance)
Parameters:
  th -



isSortKey
public boolean isSortKey(Expression child)(Code)
Test whether a given expression is one of the sort keys



iterate
public SequenceIterator iterate(XPathContext context) throws XPathException(Code)
Enumerate the results of the expression



iterateSubExpressions
public Iterator iterateSubExpressions()(Code)
Get the immediate sub-expressions of this expression. Default implementation returns a zero-length array, appropriate for an expression that has no sub-expressions. an iterator containing the sub-expressions of this expression



optimize
public Expression optimize(Optimizer opt, StaticContext env, ItemType contextItemType) throws XPathException(Code)
Perform optimisation of an expression and its subexpressions.

This method is called after all references to functions and variables have been resolved to the declaration of the function or variable, and after all type checking has been done.


Parameters:
  opt - the optimizer in use. This provides access to supporting functions; it also allowsdifferent optimization strategies to be used in different circumstances.
Parameters:
  env - the static context of the expression
Parameters:
  contextItemType - the static type of "." at the point where this expression is invoked.The parameter is set to null if it is known statically that the context item will be undefined.If the type of the context item is not known statically, the argument is set tonet.sf.saxon.type.Type.ITEM_TYPE the original expression, rewritten if appropriate to optimize execution
throws:
  net.sf.saxon.trans.StaticError - if an error is discovered during this phase(typically a type error)



promote
public Expression promote(PromotionOffer offer) throws XPathException(Code)
Offer promotion for this subexpression. The offer will be accepted if the subexpression is not dependent on the factors (e.g. the context item) identified in the PromotionOffer. By default the offer is not accepted - this is appropriate in the case of simple expressions such as constant values and variable references where promotion would give no performance advantage. This method is always called at compile time.
Parameters:
  offer - details of the offer, for example the offer to moveexpressions that don't depend on the context to an outer level inthe containing expression if the offer is not accepted, return this expression unchanged.Otherwise return the result of rewriting the expression to promotethis subexpression
throws:
  net.sf.saxon.trans.XPathException - if any error is detected



simplify
public Expression simplify(StaticContext env) throws XPathException(Code)
Simplify an expression



typeCheck
public Expression typeCheck(StaticContext env, ItemType contextItemType) throws XPathException(Code)
Type-check the expression
