Detailed Description

creates ilwisobjects

A general interface for factories for all kinds of ilwisobject. Note that is not needed that a factory can produce all types of objects. For example there exists a projectionfactory that only can produce projection objects. Factories are registered to the kernel and others can request a factory of a certain type from the kernel

Constructor & Destructor Documentation

IlwisObjectFactory::IlwisObjectFactory	(	const QString &	ty,
		const QString &	sub,
		const QString &	desc = ""
	)

constructor for a factory object

The method 2 first parameters are used to choose which factory is used

Parameters

ty	maintype of the factory. The type usualy signifies which kind objects it can produce though there is no special reason for it.
sub	subtype of the factory. Usualy used to make a choice between several types of factories that can produce the same kind of objects
desc	optional description of the factory.

Member Function Documentation

virtual IlwisObject* Ilwis::IlwisObjectFactory::create ( const Resource &  resource, const PrepareOptions &  options = PrepareOptions()  ) const

pure virtual

prototype for the mandatory creation method that all ilwisobject factories must suport

Parameters

resource

a pointer the location of the resource from which the ilwisobject is created

Returns

IlwisObject the created ilwisobject or 0 if something went wrong
