Constructor Detail

ModelImpl

public ModelImpl(String modelName)

Create a new Model with a model name.

Parameters:

modelName - the model name to identify the model

Method Detail

declareAlternativeNamespace

public void declareAlternativeNamespace(String alternativeNs,
                                        String actualNs)

Declares an alternative namespace for an actual so that during lookup of elements/attributes both will be considered. This can be used if a newer namespaces replaces an older one but XML files with the old one should still be parseable.

Parameters:

alternativeNs -

actualNs -

Throws:

IllegalArgumentException - if the alternative is already used or if the actual namespace has an alternative

undeclareAlternativeNamespace

public void undeclareAlternativeNamespace(String alternativeNs)

getAlternativeNamespace

Description copied from interface: Model

Returns the alternative namespace URI for a namespace URI

Specified by:

getAlternativeNamespace in interface Model

Parameters:

actualNs - the actual namespace URI

Returns:

the alternative namespace URI or null if none is set

getActualNamespace

public String getActualNamespace(String alternativeNs)

Description copied from interface: Model

Returns the actual namespace URI for an alternative namespace URI

Specified by:

getActualNamespace in interface Model

Parameters:

Returns:

the corresponding element type or null if no type is defined for the instance

getTypeForName

public ModelElementType getTypeForName(String typeName)

Description copied from interface: Model

Gets the defined ModelElementType for a type by its name.

Specified by:

getTypeForName in interface Model

the element type or null if no type is defined for the name and namespace URI

registerType

public void registerType(ModelElementType modelElementType,
                         Class<? extends ModelElementInstance> instanceType)
