Detailed Description

template<typename ... Classes>
class adtf::ucom::ant::class_factory< Classes >

The class class_factory provides a template based implementation of the IClassFactory interface, that can create exactly one kind of object for the class

Parameters

T.

Template Parameters

T	Class of the Object to create.
EXPLICIT_INTERFACE	If the class implementation T has ambiguous conversion to the IObject use EXPLICIT_INTERFACE to define an explicit cast.

template<typename ... Classes>

adtf::ucom::ant::class_factory< Classes >::class_factory ( )

inline

The Constructor create the class factory for exactly one object.

standard DTOR for the class factory.

Member Function Documentation

CreateInstance()

template<typename ... Classes>

virtual tResult adtf::ucom::ant::class_factory< Classes >::CreateInstance ( const char * strCID, iobject_ptr< IObject > & oObject, const tChar * strNameOfObject = "" ) const

inlinevirtual

Creates a new instance. The CreateInstance method creates a single uninitialized object of the class associated with a specified class identifier.

Parameters

[in]	strCID	Class identifier of the object to create!
[in]	strNameOfObject	ObjectName identifier (will be relevant only if the ClassFactory can handle this).
[in,out]	oObject	Object to create to be used to communicate with the object.

Returns

Returns a standard result code.

Return values

ERR_ERR_INVALID_LICENSE	no valid license found
Return	Value of iobject_ptr<IObject>::Reset() Implements the ucom::IClassFactory::CreateInstance. This Function will create an instance for given parameter class <T> .
ERR_INVALID_ARG	strCID is empty
ERR_MEMORY	the object will be created on heap. out of memory.
ERR_NO_CLASS	Given strCID is not supported by this class factory.
ERR_INVALID_INTERFACE	oObject.Get() is empty after Reseting. This could be possible if the oObject expect another interface.

GetClasses()

template<typename ... Classes>

tResult adtf::ucom::ant::class_factory< Classes >::GetClasses ( iobject_enum< const IClassInfo > & lstOfClasses ) const

inline

Enumerates all classes supported by the class factory and pushes it to lstOfClasses This method should be used for debugging or testing purposes only.

Parameters

[in,out]

lstOfClasses

List to return the class information to. Use object_list or object_vector.

Returns

Returns a standard result code.

See also

object_list, object_vector.

This function will fill the iobject_enum with only one ucom::IClassInfo Object for the class given a template parameter
