Constructor Detail

XQueryParserEE

public XQueryParserEE(String queryVersion,
              boolean updating)

Method Detail

newParser

public XQueryParser newParser()

Create a new parser of the same kind

Overrides:

newParser in class XQueryParserPE

Returns:

a new parser of the same kind as this one

getPermittedFunctions

public int getPermittedFunctions()

Get the permitted set of standard functions in this environment

Overrides:

getPermittedFunctions in class XQueryParserPE

Returns:

a code indicating which system library functions are supported in this version of the language

parseRevalidationDeclaration

protected void parseRevalidationDeclaration()
                                     throws XPathException

Overrides:

parseRevalidationDeclaration in class XQueryParser

Throws:

XPathException

parseUpdatingFunctionDeclaration

protected void parseUpdatingFunctionDeclaration()
                                         throws XPathException

Overrides:

parseUpdatingFunctionDeclaration in class XQueryParser

Throws:

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

parseExprSingle

public Expression parseExprSingle()
                           throws XPathException

XPathException - if any error is encountered

checkStreamability

public void checkStreamability(Expression exp,
                      ContextItemStaticInfo contextInfo)
                        throws XPathException

Description copied from class: XQueryParser

Check that an expression is streamable

Overrides:

checkStreamability in class XQueryParser

Parameters:

exp - the expression to be checked

contextInfo - information about the context item

Throws:

XPathException - if the expression is not streamable
