Create an OData filter expression by walking an expression tree.

공개 메소드들

메소드	설명
Create ( Expression expression ) : string	Translate an expression tree into a compiled OData query.
Visit ( Expression node ) : Expression	Visit a node of the expression.

메소드	설명
GetTableMember ( Expression expression ) : Microsoft.WindowsAzure.MobileServices.SerializableMember	Get the table member referenced by an expression or return null.
VisitBinary ( BinaryExpression expression ) : Expression	Process binary comparison operators.
VisitConstant ( ConstantExpression expression ) : Expression	Process constant values.
VisitMember ( MemberExpression expression ) : Expression	Process member references.
VisitMethodCall ( MethodCallExpression expression ) : Expression	Process method calls and translate them into OData.
VisitUnary ( UnaryExpression expression ) : Expression	Process the not operator.

FilterBuildingExpressionVisitor ( ) : System
GetFilterMethodArguments ( MethodCallExpression expression, string methodName, bool isStatic ) : IEnumerable	Returns the ordered collection of arguments for the the given OData filter method given the MethodCallExpression instance.
IsConversionImplicit ( UnaryExpression expression, Type from, Type to ) : bool	Check whether a conversion from one type to another will be made implicitly by the server. This is only considered valid for member references. This relies on the fact that all numeric types on the server are represented as doubles.
MarkVisited ( ) : void	Mark an expression as visited. This method is called when we're finished processing any expression we're accepting as a valid Mobile Services filter. Note that it must be called immediately before returning the expression (because any nested Visit calls will stomp its tracking mechanism).
StripUnaryOperator ( Expression expression ) : Expression	Remove the operator from certain unary expressions like quote or conversions we can ignore.
