Detailed Description

The FactoryInterface class general placeholder interface for all factory classes in Ilwis.

*The masterfactory stores pointers with this interface. It is a very generic interface so it must be cased toa specific type to become useful

Member Function Documentation

virtual bool Ilwis::FactoryInterface::canUse ( const Resource &  resource ) const

pure virtual

test if a resource can be used by this factory to create something from the resource

Not all factories can create all the objects of course. This method checks if a resource is usefull for a factory

Parameters

resource

the resource to be tested

Returns

bool true if the object type indicated by the resource can be created by the factory

Implemented in Ilwis::AbstractFactory.

virtual QString Ilwis::FactoryInterface::description ( ) const

pure virtual

description

Returns

a brief description whata certain factory is supposed to do. It is optional

Implemented in Ilwis::AbstractFactory.

virtual QString Ilwis::FactoryInterface::key ( ) const

pure virtual

string combinations of type subtype

Convenience method for creating a full type description for a factory

Returns

QString conbined name

Implemented in Ilwis::AbstractFactory.

virtual bool Ilwis::FactoryInterface::prepare ( )

pure virtual

prepare initializes the factory

Returns

Implemented in Ilwis::AbstractFactory, and Ilwis::GeoRefImplementationFactory.

virtual QString Ilwis::FactoryInterface::subtype ( ) const

pure virtual

subtype further specializes the search key for factories

*The subtype usualy limits the factory to a module were this factory is implemented. It is used when they are nameclashes about the type of the factory.

Returns

the name of the subtype;

Implemented in Ilwis::AbstractFactory.

virtual QString Ilwis::FactoryInterface::type ( ) const

pure virtual

type the main type of the factory.

*This member, together with the subtype is used to select factories from the masterfactory.

Returns

the name of the type

Implemented in Ilwis::AbstractFactory.
