XPath(String xpath, SymbolTable symbolTable, NamespaceContext context)

Constructs an XPath object from the specified expression.

Method Summary

Modifier and TypeMethod and Description
private XPath.LocationPath
buildLocationPath(Vector<E> stepsVector)

Used by the parseExpression(NamespaceContext) method to build a LocationPath object from the accumulated Steps.

private static void
check(boolean b)

Used by the parseExpression(NamespaceContext) method to verify the assumption.

public XPath.LocationPath
getLocationPath()

Returns a representation of the first location path for this XPath.

public XPath.LocationPath[]
getLocationPaths()

Returns a representation of all location paths for this XPath.

public static void
main(String[] argv)

Main program entry.

private XPath.LocationPath[]
parseExpression(final NamespaceContext context)

This method is implemented by using the XPathExprScanner and examining the list of tokens that it returns.

private XPath.NodeTest
parseNodeTest(int typeToken, XPath.Tokens xtokens, NamespaceContext context)

Used by parseExpression to parse a node test from the token list.
