Interface IUserDataType

As a convenience, every type deriving from IUserDataType is "self-described". That is, no descriptor is needed/generated and the object itself is used to describe the type for interop. See also UserData, IUserDataDescriptor and StandardUserDataDescriptor .

Namespace: System.Dynamic.ExpandoObject

Assembly: cs.temp.dll.dll

Syntax

public interface IUserDataType

Methods

Index(Script, DynValue, Boolean)

Performs an "index" "get" operation.

Declaration

DynValue Index(Script script, DynValue index, bool isDirectIndexing)

Parameters

Script script The script originating the request

DynValue index The index.

System.Boolean isDirectIndexing If set to true, it's indexed with a name, if false it's indexed through brackets.

Returns

DynValue

MetaIndex(Script, String)

Gets a "meta" operation on this userdata. If a descriptor does not support this functionality, it should return "null" (not a nil).

These standard metamethods can be supported (the return value should be a function accepting the classic parameters of the corresponding metamethod): __add, __sub, __mul, __div, __div, __pow, __unm, __eq, __lt, __le, __lt, __len, __concat, __pairs, __ipairs, __iterator, __call

These standard metamethods are supported through other calls for efficiency: __index, __newindex, __tostring

Declaration

DynValue MetaIndex(Script script, string metaname)

Parameters

Script script The script originating the request

System.String metaname The name of the metamember.

Returns

DynValue

SetIndex(Script, DynValue, DynValue, Boolean)

Performs an "index" "set" operation.

Declaration

bool SetIndex(Script script, DynValue index, DynValue value, bool isDirectIndexing)

Parameters

Script script The script originating the request

DynValue index The index.

DynValue value The value to be set

System.Boolean isDirectIndexing If set to true, it's indexed with a name, if false it's indexed through brackets.

Returns

System.Boolean
