TXIMPGetInterface Class Reference

class TXIMPGetInterface

Interface query and type cast helper.

Templated interface query and type cast helper. Capable to retrieve const interface from const source object and non-const interface from non-const source object.

Const interface usage example:

 const MXIMPBase* obj = GetObjectImplementingTheInterfaceLC();

 const MXimpFwTheInterface* theInterface =
      TXIMPGetInterface< const MXimpFwTheInterface >::From( *obj,
                                                          MXIMPBase::EPanicIfUnknown );
 theInterface->DoSomething();

Non-const interface usage example:

 MXIMPBase* obj = GetObjectImplementingTheInterfaceLC();

 MXimpFwTheInterface* theInterface =
      TXIMPGetInterface< MXimpFwTheInterface >::From( *obj,
                                                    MXIMPBase::EPanicIfUnknown );
 theInterface->DoSomething();

From(const MXIMPBase &, MXIMPBase::TIfGetOps)

T *	From	(	const MXIMPBase &	aObj,
			MXIMPBase::TIfGetOps	aOps
		)	[static, inline]

Interface query and type cast.

Encapsulates query of const interface from given const source object. The retrieved interface type is defined with template parameter. KInterfaceId identifier from template parameter, is used to identify the retrieved interface.

Parameters

const MXIMPBase & aObj	Source object from where to retrieve interface.
MXIMPBase::TIfGetOps aOps	Options for interface resolving. Given options are delivered directly to MXIMPBase::GetInterface().
