Method Details

lookupStar

public Expression lookupStar(Expression lhs,
 SequenceType type,
 boolean allow40)

Supporting code for lookup expressions (A?B) where B is the wildcard "*"

Overrides:

lookupStar in class ParserExtension

Parameters:

lhs - the LHS operand of the lookup expression

allow40 -

Returns:

the result of parsing the expression

parseRevalidationDeclaration

public void parseRevalidationDeclaration(XQueryParser p)
                                  throws XPathException

Parse the "declare revalidation" declaration (XQuery Update). Syntax: <"declare" "revalidation"> ("strict" | "lax" | "skip")

Overrides:

parseRevalidationDeclaration in class ParserExtension

Parameters:

p - the XPath parser

Throws:

XPathException - if the declaration is invalid or duplicated

parseUpdatingFunctionDeclaration

public void parseUpdatingFunctionDeclaration(XQueryParser p)
                                      throws XPathException

Parse an updating function declaration (allowed in XQuery Update only)

Overrides:

parseUpdatingFunctionDeclaration in class ParserExtension

Parameters:

p - the XPath parser

Throws:

XPathException - if parsing fails PathMapor if updating functions are not allowed

parseExtendedExprSingle

protected Expression parseExtendedExprSingle(XPathParser p)
                                      throws XPathException

Parse an ExprSingle

Overrides:

parseExtendedExprSingle in class ParserExtension

Returns:

the resulting subexpression

Throws:

XPathException - if any error is encountered

processSchemaImports

public void processSchemaImports(QueryModule module,
 List<XQueryParser.Import> schemaImports)
                          throws XPathException

Overrides:

processSchemaImports in class ParserExtension

Throws:

XPathException

parseDeepUpdateExpression

public Expression parseDeepUpdateExpression(XQueryParser parser)
                                     throws XPathException

Parse an update map|array Expression.

Overrides:

parseDeepUpdateExpression in class ParserExtension

Returns:

the parsed expression; except that this version of the method always throws an exception

Throws:

XPathException - if a static error is found
