공개 메소드들

메소드	설명
ConvertToFieldPredicate ( BinaryExpression expression, AbstractQueryStructureBinder structureBinder ) : Expression	Converts a BinaryExpression to a field predicate expression, if supported and convertible.
GetFieldSelector ( Expression left, AbstractQueryStructureBinder structureBinder ) : FieldSelectorExpression
GetFieldSelector ( Expression left, AbstractQueryStructureBinder structureBinder, BindingSignatureSupport bindingSignatureSupport ) : FieldSelectorExpression	Gets a FieldSelectorExpression from an expression it the bindingSignatureSupport identifies it as supported.
IsConvertibleBinary ( BinaryExpression expression, AbstractQueryStructureBinder structureBinder ) : bool	Determines whether the supplied BinaryExpression is convertible to a binary in the context of the featureset of the Rebel Framework-supported expression tree.
NegateFieldPredicate ( FieldPredicateExpression fieldPredicateExpression ) : FieldPredicateExpression	Negates a field predicate, i.e. reverses its ValuePredicateType for example Equals will be switched to NotEquals.
