Приватные методы

Метод	Описание
AddStepPattern ( QilNode nd, QilNode input ) : void	Mark the specified node as matching the Step pattern and set the step node and step input arguments.
AllowDodReverse ( QilNode nd ) : bool	True if the DodReverse pattern is allowed to match the specified node.
AllowJoinAndDod ( QilNode nd ) : bool	True if the JoinAndDod pattern is allowed to match the specified node.
AreLiteralArgs ( QilNode nd ) : bool	Return true if all children of "nd" are constant.
CanFoldArithmetic ( QilNodeType opType, QilLiteral left, QilLiteral right ) : bool	Return true if arithmetic operation "opType" can be computed over two literal operands without causing an overflow or divide by zero exception.
CanFoldXsltConvert ( QilNode ndLiteral, XmlQueryType typTarget ) : bool	Return true if XsltConvert applied to a Literal can be folded (i.e. the XsltConvert eliminated).
CanFoldXsltConvertNonLossy ( QilNode ndLiteral, XmlQueryType typTarget ) : bool	Return true if XsltConvert applied to a Literal can be folded (i.e. the XsltConvert eliminated), without any loss of information.
DependsOn ( QilNode expr, QilNode target ) : bool	Returns true if any operator within the "expr" subtree references "target".
ExtractLiteralValue ( QilNode nd ) : object	Extract the value of a literal.
FoldArithmetic ( QilNodeType opType, QilLiteral left, QilLiteral right ) : QilNode	Compute the arithmetic operation "opType" over two literal operands and return the result as a QilLiteral. Arithmetic operations are always checked; in the case of an overflow or divide by zero exception, return the unfolded result.
FoldComparison ( QilNodeType opType, QilNode left, QilNode right ) : QilNode	Compute the arithmetic operation "opType" over two literal operands and return the result as a QilLiteral. In the case of an overflow or divide by zero exception, return the unfolded result.
FoldXsltConvert ( QilNode ndLiteral, XmlQueryType typTarget ) : QilNode	Fold a XsltConvert applied to a Literal into another Literal. If the fold results in some kind of conversion error, or if the QilExpression cannot represent the result as a Literal, return an unfolded XsltConvert expression.
HasNestedSequence ( QilNode nd ) : bool	Return true if "nd" has a child of type Sequence.
IsConstructedExpression ( QilNode nd ) : bool	True if the specified expression constructs one or more nodes using QilExpression constructor operators. This information is used to determine whether the results of a function should be streamed to a writer rather than cached.
IsDocOrderDistinct ( QilNode nd ) : bool	Return true if "nd" matches the Step pattern and the StepType argument is equal to "stepType".
IsGlobalVariable ( QilIterator iter ) : bool	True if the specified iterator is a global variable Let iterator.
IsLiteral ( QilNode nd ) : bool	True if the specified expression is a literal value.
IsPrimitiveNumeric ( XmlQueryType typ ) : bool	Return true if "typ" is xs:decimal=, xs:integer=, xs:int=, xs:double=, or xs:float=.
IsStepPattern ( OptimizerPatterns patt, QilNodeType stepType ) : bool	Return true if "patt" matches the Step pattern and the StepType argument is equal to "stepType".
IsStepPattern ( QilNode nd, QilNodeType stepType ) : bool	Return true if "nd" matches the Step pattern and the StepType argument is equal to "stepType".
MatchesContentTest ( XmlQueryType typ ) : bool	Returns true if "typ" matches one of the XPath content node tests: *, text(), comment(), pi(), or node().
Subs ( QilNode expr, QilNode refOld, QilNode refNew ) : QilNode	Scans "expr" subtree, looking for "refOld" references and replacing them with "refNew" references.
XmlILOptimizerVisitor ( ) : System
this ( XmlILOptimization ann ) : bool	Selectively enable/disable optimizations
