Detailed Description

IClassInfo represents meta-class information for a boss class, allowing callers to iterate through interfaces and implementations of a boss class. You can get an IClassInfo interface for a particular boss class from IObjectModel. It provides generic information about all boss objects of a given class: what interfaces they support, what implementations they use, etc.

See Also: IObjectModel

Member Function Documentation

virtual int32 IClassInfo::CountInterfaces ( ) const

pure virtual

Return the total number of interfaces supported by the class.

Returns: number of interfaces supported by the class.

virtual void IClassInfo::FinalizeClassInfo ( )

pure virtual

Forces the Class Info to finalize. Used internally during the first startup. Should not be called by regular code.

virtual std::pair<InterfaceInfo const*, int32> IClassInfo::FindInterfaceInfo ( PMIID interfaceID ) const

pure virtual

Looks up the InterfaceInfo asociated with the specified PMIID. Returns a pair of the InterfaceInfo pointer and interface index. The pair is useful when the caller needs to know the index of this PMIID as well (it avoids and extra lookup). If the class info doesn't support this interface returns a pair of (nil, -1).

virtual ClassID IClassInfo::GetClass ( ) const

pure virtual

Return the ID of the class that this classinfo represents.

Returns: the ClassID of the class

Implements IControllingUnknown.

virtual PMIID IClassInfo::GetIID ( ImplementationID whichInterface ) const

pure virtual

Given the implementationID, find the corresponding IID.

Parameters

whichInterface the ImplementationID of the interface we want to find out about

Returns: the IID (InterfaceID) of the interface, or IID_IUNKNOWN

virtual ImplementationID IClassInfo::GetImplementation ( PMIID whichInterface ) const

pure virtual

Given the interfaceID (IID), find the corresponding ImplementationID

Parameters

whichInterface the IID of the interface within the boss

Returns: the ImplementationID used to implement the interface, or kInvalidImpl

virtual ImplementationID IClassInfo::GetImplementationByIndex ( int32 interfaceIndex ) const

pure virtual

Given the index of an interfaceID (IID), find the corresponding ImplementationID

Parameters

interfaceIndex the index of the interface within the boss(probably from calling GetIndex previously)

Returns: the ImplementationID used to implement the interface, or kInvalidImpl

virtual PMIID IClassInfo::GetInterface ( int32 index ) const

pure virtual

Return the n'th supported interface. Used together with

CountInterfaces, this allows callers to iterate over the interfaces.

Parameters

index the index of the interface within the boss

Returns: n'th supported interface.

virtual PluginID IClassInfo::GetOwnerComponent ( PMIID forWhat = IID_IUNKNOWN ) const

pure virtual

Return the ID of the plug-in that registered the class.

Parameters

forWhat the interface we want to find out about (or nothing to find out the owner of the class)

Returns: the PluginID of the plug-in that added the interface into the boss (or supplied the boss itself, if IID_IUNKNOWN)

virtual ClassID IClassInfo::GetParentClass ( ) const

pure virtual

Return the parent (base) class that this class is derived from, 

or kInvalidClass if there is no parent.

Returns: the ClassID of the parent (base) class
