Method Detail

addToPathMap

Add a representation of this expression to a PathMap. The PathMap captures a map of the nodes visited by an expression in a source tree.

Parameters: pathMap the PathMap to which the expression should be added pathMapNodeSet

Returns: the pathMapNode representing the focus established by this expression, in the case where this expression is the first operand of a path expression or filter expression

checkArguments

computeSpecialProperties

getResolverResults

public static SequenceIterator getResolverResults(SequenceIterator iter, String baseURI, XPathContext context, SourceLocator locator)

getStaticBaseURI

iterate

Iterate over the contents of the collection

Parameters: context the dynamic context

Returns: an iterator, whose items will always be nodes (typically but not necessarily document nodes)

Throws: XPathException

preEvaluate

preEvaluate: this method suppresses compile-time evaluation by doing nothing

Parameters: visitor an expression visitor
