This interface allows ITypeInfo to cast to an ITypeInfo2 in performance-sensitive cases. An ITypeInfo can be cast to an ITypeInfo2 instead of using the calls IUnknown::QueryInterface and IUnknown::Release. This casting procedure is not compatible with Windows 95 or Microsoft Windows NT® version 3.51.

Methods

The following table shows the methods for this interface in the order that the compiler calls the methods. Like all COM interfaces, this interface inherits the methods for the IUnknown interface. This interface also inherits the methods for the ITypeInfo interface.

Method	Description
ITypeInfo2::GetTypeKind	This method returns the TYPEKIND enumeration quickly, without doing any allocations.
ITypeInfo2::GetTypeFlags	This method returns the TYPEFLAGS quickly, without doing any allocations.
ITypeInfo2::GetFuncIndexOfMemId	This method binds to a specific member based on a known dispatch identifier (DISPID).
ITypeInfo2::GetVarIndexOfMemId	This method binds to a specific member based on a known dispatch identifier (DISPID).
ITypeInfo2::GetCustData	This method gets the custom data.
ITypeInfo2::GetFuncCustData	This method gets the custom data from the specified function.
ITypeInfo2::GetParamCustData	This method gets the specified custom data parameter.
ITypeInfo2::GetVarCustData	This method gets the variable for the custom data.
ITypeInfo2::GetImplTypeCustData	This method gets the implementation type of the custom data.
ITypeInfo2::GetDocumentation2	This method retrieves the documentation string and other Help-related information.
ITypeInfo2::GetAllCustData	This method gets all custom data items for the library.
ITypeInfo2::GetAllFuncCustData	This method gets all of the custom data from the specified function.
ITypeInfo2::GetAllParamCustData	This method gets all of the custom data for the specified parameter.
ITypeInfo2::GetAllVarCustData	This method gets all of the custom data for the specified variable.
ITypeInfo2::GetAllImplTypeCustData	This method gets all of the custom data for the specified implementation type.
