Method Summary

ValueRepresentation

evaluateVariable(XPathContext context)

Evaluate the variable (method exists only to satisfy the interface)

void

explain(ExpressionPresenter out)

Diagnostic print of expression structure.

void

fixup(Binding binding)

int

getInstructionNameCode()

Get the name of this instruction for diagnostic and tracing purposes

int

getIntrinsicDependencies()

TailCall

processLeavingTail(XPathContext context)

Expression

promote(PromotionOffer offer, Expression parent)

Offer promotion for this subexpression.

void

setStaticType(SequenceType type, Value constantValue, int properties)

Method Detail

Evaluate the variable (method exists only to satisfy the interface)

Diagnostic print of expression structure. The abstract expression tree is written to the supplied output destination.

public void fixup(Binding binding)

public int getInstructionNameCode()

Get the name of this instruction for diagnostic and tracing purposes

public int getIntrinsicDependencies()

public TailCall processLeavingTail(XPathContext context)

Offer promotion for this subexpression. This needs careful handling in the case of saxon:assign

Parameters: offer details of the offer, for example the offer to move expressions that don't depend on the context to an outer level in the containing expression parent

Returns: if the offer is not accepted, return this expression unchanged. Otherwise return the result of rewriting the expression to promote this subexpression

Throws: net.sf.saxon.trans.XPathException if any error is detected
