                         ModelBuilder modelBuilder,
                         DomDocument document)

Method Detail

getDocument

public DomDocument getDocument()

Description copied from interface: ModelInstance

Returns the wrapped DomDocument.

Specified by:

getDocument in interface ModelInstance

Returns:

the DOM document

getDocumentElement

public ModelElementInstance getDocumentElement()

Description copied from interface: ModelInstance

Returns the ModelElement corresponding to the document element of this model or null if no document element exists.

Specified by:

getDocumentElement in interface ModelInstance

Returns:

the document element or null

setDocumentElement

public void setDocumentElement(ModelElementInstance modelElement)

Description copied from interface: ModelInstance

Updates the document element.

Specified by:

setDocumentElement in interface ModelInstance

Parameters:

modelElement - the new document element to set

newInstance

public <T extends ModelElementInstance> T newInstance(Class<T> type)

Description copied from interface: ModelInstance

Creates a new instance of type class.

Specified by:

newInstance in interface ModelInstance

Type Parameters:

T - instance type

Parameters:

type - the class of the type to create

Returns:

the new created instance

newInstance

public <T extends ModelElementInstance> T newInstance(ModelElementType type)

Description copied from interface: ModelInstance

Creates a new instance of type.

Specified by:

newInstance in interface ModelInstance

Type Parameters:

T - instance type

Parameters:

type - the type to create

Returns:

the new created instance

getModel

public Model getModel()

Description copied from interface: ModelInstance

Returns the underlying model.

Specified by:

getModel in interface ModelInstance

Returns:

the model

registerGenericType

public ModelElementType registerGenericType(String namespaceUri,
                                            String localName)

getModelElementById

public <T extends ModelElementInstance> T getModelElementById(String id)

Description copied from interface: ModelInstance

Find a unique element of the model by id.

Specified by:

getModelElementById in interface ModelInstance

Parameters:

id - the id of the element

Returns:

the element with the id or null

getModelElementsByType

public Collection<ModelElementInstance> getModelElementsByType(ModelElementType type)

Description copied from interface: ModelInstance

Find all elements of a type.

Specified by:

getModelElementsByType in interface ModelInstance

Parameters:

type - the type of the elements

Returns:

the collection of elements of the type

getModelElementsByType

public <T extends ModelElementInstance> Collection<T> getModelElementsByType(Class<T> referencingClass)

Description copied from interface: ModelInstance

Find all elements of a type.

Specified by:

getModelElementsByType in interface ModelInstance

Parameters:

referencingClass - the type class of the elements

Returns:

the collection of elements of the type

clone

public ModelInstance clone()

Description copied from interface: ModelInstance

Copies the model instance but not the model. So only the wrapped DOM document is cloned. Changes of the model are persistent between multiple model instances.

Specified by:

clone in interface ModelInstance

Overrides:

clone in class Object

Returns:

the new model instance

validate

public ValidationResults validate(Collection<ModelElementValidator<?>> validators)

Description copied from interface: ModelInstance

Validate semantic properties of this model instance using a collection of validators. ModelElementValidator is an SPI that can be implemented by the user to execute custom validation logic on the model. The validation results are collected into a ValidationResults object which is returned by this method.

Specified by:

validate in interface ModelInstance

Parameters:

validators - the validators to execute

Returns:

the results of the validation.
