Class EMFModelProvider

org.eclipse.core.runtime.PlatformObject

All Implemented Interfaces:

public class EMFModelProvider extends org.eclipse.core.resources.mapping.ModelProvider
This implementation of a ModelProvider will be used to provide the logical model associated with EMF models.

Concretely, an EMF model can span multiple physical resources (fragmented models); this model provider can be used to find all of these associated physical resources. Note that a model can span remote resources that do not exist locally; these will be accounted for when using this model with a RemoteResourceMappingContext.

  • Field Details

    • PROVIDER_ID

      public static final String PROVIDER_ID
      ID of this model provider. Must match the definition from the plugin.xml.
      See Also:
    • CACHE_EXPIRATION

      public static final long CACHE_EXPIRATION
      The expiration timeout for our logical model cache values. This might mean that some of the returned mappings might reflect a stale view of the files' logical models, but we expect said logical traversals not to change that often.

      Basically, the mappings are used by the platform to determine whether a file can be moved, replaced or compared alone or if in the contrary the action's scope must be expanded, and will do so very often in short intervals. We will cache the result in order to avoid multiple identical computation to take place and hasten the whole process.
