Constructor Detail

ApplyImports

public ApplyImports(boolean backwardsCompatible)

Method Detail

createsNewNodes

public final boolean createsNewNodes()

Determine whether this instruction creates new nodes. This implementation returns true (which is almost invariably the case, so it's not worth doing any further analysis to find out more precisely).

display

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

Diagnostic print of expression structure. The expression is written to the System.err output stream

Parameters: level indentation level for this expression out

getInstructionNameCode

public int getInstructionNameCode()

Get the name of this instruction for diagnostic and tracing purposes

Get all the XPath expressions associated with this instruction (in XSLT terms, the expression present on attributes of the instruction, as distinct from the child instructions in a sequence construction)

optimize

public Expression optimize(Optimizer opt, StaticContext env, ItemType contextItemType)

processLeavingTail

public TailCall processLeavingTail(XPathContext context)

promoteInst

protected void promoteInst(PromotionOffer offer)

Handle promotion offers, that is, non-local tree rewrites.

Parameters: offer The type of rewrite being offered

Throws: XPathException

setActualParameters

public void setActualParameters(WithParam[] actualParams, WithParam[] tunnelParams)

Set the actual parameters on the call

simplify

public Expression simplify(StaticContext env)

Simplify an expression. This performs any static optimization (by rewriting the expression as a different expression).

Returns: the simplified expression

Throws: net.sf.saxon.trans.XPathException if an error is discovered during expression rewriting

typeCheck

public Expression typeCheck(StaticContext env, ItemType contextItemType)
