Package de.uni_trier.wi2.procake.data.model

Class ModelFactory

java.lang.Object

de.uni_trier.wi2.procake.data.model.ModelFactory

All Implemented Interfaces:

Factory

public class ModelFactory
extends Object
implements Factory

This is the factory class to access the implementations to the data model interfaces.

The system contains one default model that can be accessed via getDefaultModel(). It can also manage several other models that can be created by the method newModel(String)}.

Method Detail

bind

public static boolean bind(ModelFactoryObject implementation)

getDefaultModel

public static Model getDefaultModel()

Returns:

The system default Model.

getModel

public static Model getModel(String name)

Parameters:

name - model name defined in composition.xml

Returns:

The model Model with the given name.

getModelPath

public static String getModelPath(String name)

Parameters:

name - model name defined in composition.xml

Returns:

The model path with the given name.

newModel

public static Model newModel(String name)

This method creates a new model and may overwrite an existing models with the same name.

Parameters:

name - The name of the new model. If name equals DEFAULT_MODEL_NAME, the new Model will be the default Model. It is not possible to go back to the previous model.

Returns:

newAttributePath

public static AttributePath newAttributePath()

Creates a new AttributePaththat can be used to resolve attributes in AggregateObjects. For example, via AggregateObject.resolveAttributeValue(AttributePath) the value of the defined attribute path is returned.

Returns:

A new AttributePath object.

unbind

public static boolean unbind(ModelFactoryObject implementation)

reset

public void reset()

Description copied from interface: Factory

This method has to be implemented by every factory in order to allow a proper restart of ProCAKE. For example, this method might reset the default factory object or other stateful variables.

Specified by:

reset in interface Factory

bind

public boolean bind(Object implementation)

Description copied from interface: Factory

Bind an implementation to the factory.

Specified by:

bind in interface Factory

Parameters:

implementation -

Returns:

Returns true if the bind was successful

See Also:

Factory.bind(java.lang.Object)

unbind

public boolean unbind(Object implementation)

Description copied from interface: Factory

Unbinds an implementation from the factory.

Specified by:

unbind in interface Factory

Parameters:

implementation -

Returns:

Returns true if the unbind was successful
