getQualifiedClassName

Constructor Detail

TargetPlatformMetamodelProviderService

public TargetPlatformMetamodelProviderService()

Method Detail

getIdentifier

public java.lang.String getIdentifier()

Description copied from interface: IMetamodelProviderInstance

Get a textual identifier for the metamodel provider instance

Specified by:

getIdentifier in interface IMetamodelProviderInstance

Returns:

a non-null textual identifier; should be unique over all possible implementations

getPriority

public int getPriority()

Description copied from interface: IMetamodelProviderInstance

A default priority for the provider instance; a lower number means a higher priority. The priority may be overriden through CompoundMetamodelProviderService.

Specified by:

getPriority in interface IMetamodelProviderInstance

Returns:

a non-negative priority number

isGeneratedCodeAvailable

public boolean isGeneratedCodeAvailable(org.eclipse.emf.ecore.EPackage ePackage,
                                        org.eclipse.emf.ecore.resource.ResourceSet set)

Description copied from interface: IMetamodelProvider

Returns true if the generated code is available for the given EPackage, the code uses the given resource set as context.

Specified by:

isGeneratedCodeAvailable in interface IMetamodelProvider

Overrides:

isGeneratedCodeAvailable in class BaseMetamodelProviderService

Parameters:

ePackage - for which the availability of generated code is checked

set - used for context in the checking

Returns:

true, if the generated code for the EPackage is available

getModelPluginId

public java.lang.String getModelPluginId(org.eclipse.emf.ecore.EPackage ePackage,
                                         org.eclipse.emf.ecore.resource.ResourceSet set)

Description copied from interface: IMetamodelProvider

Returns the identifier of the plugin that contains the generated model code.

Specified by:

getModelPluginId in interface IMetamodelProvider

Overrides:

getModelPluginId in class BaseMetamodelProviderService

Parameters:

ePackage - for which the model plugin ID is requested

set - used for context in the searching

Returns:

the model plugin ID or null if it cannot be found

getProvidedMetamodels

protected java.util.Collection<java.lang.String> getProvidedMetamodels()

Specified by:

getProvidedMetamodels in class BaseMetamodelProviderService

getAllMetamodelObjects

public org.eclipse.xtext.scoping.IScope getAllMetamodelObjects(org.eclipse.xtext.scoping.IScope delegateScope,
                                                               org.eclipse.emf.ecore.EObject context)

Description copied from interface: IMetamodelProvider

Returns a set of all available EPackages wrapped into IEObjectDescription for the use of scoping. It uses the IEObjectDescriptions from the delegate scope provider too, this way the EPackages from the XText index will be available too.

Specified by:

getAllMetamodelObjects in interface IMetamodelProvider

Overrides:

getAllMetamodelObjects in class BaseMetamodelProviderService

Parameters:

delegateScope - the delegate scope

context - the context object for the scoping

internalFindGenPackage

protected org.eclipse.emf.codegen.ecore.genmodel.GenPackage internalFindGenPackage(org.eclipse.emf.ecore.resource.ResourceSet resourceSet,
                                                                                   java.lang.String packageUri)

loadEPackage

public org.eclipse.emf.ecore.EPackage loadEPackage(java.lang.String packageUri,
                                                   org.eclipse.emf.ecore.resource.ResourceSet resourceSet)

Description copied from interface: IMetamodelProvider

Loads an EMF package from the nsURI or resource URI of the model, and uses the resource set given as the second parameter.

Specified by:

loadEPackage in interface IMetamodelProvider

Returns:

the loaded EMF EPackage
