public final class ModelMappingService
extends org.eclipse.gmf.runtime.common.core.service.Service
implements IModelMappingProvider

This class provides a service to interact with all providers implementing IModelMappingProvider interface, and registered with com.ibm.xtools.mmi.core.IModelMappingProviders extension point. This service provides default implementation for IModelMappingProvider, where in it finds appropiate provider based on ExecutionStrategy.FIRST and delegates the call to that provider.

Method Summary

Modifier and Type	Method and Description
org.eclipse.emf.ecore.EObject	adapt(org.eclipse.emf.transaction.TransactionalEditingDomain domain, java.lang.Object object, org.eclipse.emf.ecore.EClass langKind) Adapts object to an EObject of a given metatype targetKind.
boolean	canAdapt(org.eclipse.emf.transaction.TransactionalEditingDomain domain, java.lang.Object object, org.eclipse.emf.ecore.EClass langKind) Testing mechanism to determine whether this provider can adapt a given object to an EObject of a particular meta-type targetKind.
boolean	canResolve(org.eclipse.emf.transaction.TransactionalEditingDomain domain, StructuredReference vr, org.eclipse.emf.ecore.EClass eClass) Testing mechanism to determine whether this provider can resolve a given vr to an EObject, based on information encoded in StructuredReference.
static ModelMappingService	getInstance() Retrieves the singleton instance of the ModelMappingService.
protected org.eclipse.gmf.runtime.common.core.service.Service.ProviderDescriptor	newProviderDescriptor(org.eclipse.core.runtime.IConfigurationElement element)
org.eclipse.emf.ecore.EObject	resolve(org.eclipse.emf.transaction.TransactionalEditingDomain domain, StructuredReference vr, org.eclipse.emf.ecore.EClass eClass) Resolves vr to a proper EObject, based on information encoded in StructuredReference
static boolean	typeMatches(java.lang.Object object, java.lang.String type) Returns if the specified Object matches the type specified as a String.
