Public Methods

Method	Description
CanConvertFrom ( Type fromType, Type toType, bool toNotNullable, NarrowingLevel level ) : bool	Determines if a conversion exists from fromType to toType at the specified narrowing level. toNotNullable is true if the target variable doesn't allow null values.
Convert ( object obj, Type toType ) : object	Converts an object at runtime into the specified type.
ConvertExpression ( Expression expr, Type toType, ConversionResultKind kind, Microsoft.Scripting.Actions.Calls.OverloadResolverFactory resolverFactory ) : Expression	Converts the provided expression to the given type. The expression is safe to evaluate multiple times.
GetAllExtensionMembers ( Type type, string name ) : MemberGroup	Gets the extension members of the given name from the provided type. Base classes are also searched for their extension members. Once any of the types in the inheritance hierarchy provide an extension member the search is stopped.
GetExtensionMembers ( Type declaringType, string name ) : MemberGroup	Gets the extension members of the given name from the provided type. Subclasses of the type and their extension members are not searched.
GetExtensionTypes ( Type t ) : IList
GetMember ( MemberRequestKind action, Type type, string name ) : MemberGroup	Gets the members that are visible from the provided type of the specified name. The default implemetnation first searches the type, then the flattened heirachy of the type, and then registered extension methods.
GetObjectTypeName ( object arg ) : string
GetTypeName ( Type t ) : string
IncludeExtensionMember ( MemberInfo member ) : bool
MakeCallExpression ( Microsoft.Scripting.Actions.Calls.OverloadResolverFactory resolverFactory, MethodInfo method ) : DynamicMetaObject
MakeContainsGenericParametersError ( MemberTracker tracker ) : ErrorInfo
MakeConversionError ( Type toType, Expression value ) : ErrorInfo
MakeGenericAccessError ( MemberTracker info ) : ErrorInfo
MakeMissingMemberError ( Type type, DynamicMetaObject self, string name ) : ErrorInfo	Provides a way for the binder to provide a custom error message when lookup fails. Just doing this for the time being until we get a more robust error return mechanism. Deprecated, use the non-generic version instead
MakeMissingMemberErrorForAssign ( Type type, DynamicMetaObject self, string name ) : ErrorInfo
MakeMissingMemberErrorForAssignReadOnlyProperty ( Type type, DynamicMetaObject self, string name ) : ErrorInfo
MakeMissingMemberErrorForDelete ( Type type, DynamicMetaObject self, string name ) : ErrorInfo
MakeMissingMemberErrorInfo ( Type type, string name ) : ErrorInfo
MakeSetValueTypeFieldError ( Microsoft.Scripting.Actions.FieldTracker field, DynamicMetaObject instance, DynamicMetaObject value ) : ErrorInfo
MakeStaticAssignFromDerivedTypeError ( Type accessingType, DynamicMetaObject self, MemberTracker assigning, DynamicMetaObject assignedValue, Microsoft.Scripting.Actions.Calls.OverloadResolverFactory context ) : ErrorInfo	Called when a set is attempting to assign to a field or property from a derived class through the base class. The default behavior is to allow the assignment.
MakeStaticPropertyInstanceAccessError ( PropertyTracker tracker, bool isAssignment ) : ErrorInfo
MakeStaticPropertyInstanceAccessError ( PropertyTracker tracker, bool isAssignment, IList parameters ) : ErrorInfo	Creates an ErrorInfo object when a static property is accessed from an instance member. The default behavior is throw an exception indicating that static members properties be accessed via an instance. Languages can override this to customize the exception, message, or to produce an ErrorInfo object which reads or writes to the property being accessed.
PreferConvert ( Type t1, Type t2 ) : Candidate	Provides ordering for two parameter types if there is no conversion between the two parameter types.
ReturnMemberTracker ( Type type, MemberTracker memberTracker ) : DynamicMetaObject	Provides an opportunity for languages to replace all MemberTracker's with their own type. Alternatlely a language can expose MemberTracker's directly.
