Public Member Functions
pure virtual TBool	Accept(const CCTTokenTypeInfo &)

Detailed Description

A filter that is used to control which token types appear in a list returned by CCTTokenTypeInfo::ListL().

Each possible token type is offered to the filter in turn, which returns ETrue if it is to be included.

For most clients one of the following three defined subclasses will do what is wanted:

TCTAllTokenTypes -- returns everything
TCTFindTokenTypesByInterface -- finds token types that support all of a supplied set of interfaces
TCTFindTokenTypesByInterfaceAndAttribute -- finds token types that match a particular list of interfaces, and a particular set of attribute/value pairs.

Clients wanting more unusual matching criteria may need to write their own subclasses.
